Most Sustainable Water-saving Faucets and Nozzles: Research, Water-savings, and User Feedback

Water conservation is a foundation of One Community’s open source strategy for building a global collaboration of self-sufficient and self-sustainable teacher/demonstration communities, villages, and cities for The Highest Good of All. One of the biggest ways to conserve water is through modifications to daily habits that use a lot of water. Using water-saving faucets and/or water-saving faucet additions is one way to do this, especially in commercial environments. With this in mind, we have researched the best water-saving faucets and faucet accessories as part of our open source contribution to comprehensive sustainable living. This page is a collection of our initial research and will evolve with our experience. It contains the following sections:

Each company was benchmarked looking at five different categories of sustainability. These consisted of: (1) if there was a sustainability presence on their website (2) if there was a current sustainability report on their website or available to the public (3) what are their sustainability goals (4) what are their sustainability initiatives and (5) what partnerships/collaborations do they have with other organizations. Taking all of this data into consideration, we were able to rank them from most sustainable to least. Sloan was the most sustainable company, but not far behind was Toto. The third most sustainable was Kohler, next was GROHE, Moen, and then American Standard coming in last and as the least sustainable faucet company.

NOTE: New technology is always being invented, check the company websites for their newest models. Even as this page becomes dated, the featured products below can be used as a good base-level starting point for your selection process. We wouldn’t recommend any product that doesn’t meet or surpass the quality and performance of the products listed here. This is how we intend to use this page as we build the Duplicable City Center and 7 sustainable village models. If better products are found when we start making our purchases, we’ll open source share here what they are and our personal experience using them. 

 

#1 MOST SUSTAINABLE FAUCET COMPANY: SLOAN

The two most sustainable companies, Sloan and Toto, were close for the most sustainable company because they both had highly detailed sustainability sections on their websites. They also had current sustainability reports and efficient products with sustainable technologies built into them. Sloan was chosen as the number one choice of these two because they had the most updated sustainability report. It was from the current year and impressively comprehensive. We found Sloan to be a very transparent company that shares a lot about what they are doing in regards to sustainability within their company and in their products technologies. As one example, they use Environmental Product Declarations (EPD) on all of their products to show the effects these products have on the environment through the product’s entire life cycle. They provide individual reports on each faucet with this information. They are also committed to being LEED v4 compliant.

Additionally, Sloan is partnered with Arbor Day, a sustainable organization that plants trees to offset the carbon footprint of the products Sloan creates. Sloan computes the carbon footprint of a product and then Arbor Day offers reforestation credits to offset this footprint. Sloan partners with many other sustainability-focused organizations too, like WaterSense (a program within the EPA), The Water Council, and the Alliance for Water Stewardship. For the full list of Sloan’s partners, take a look at the Benchmarking Tab on our research spreadsheet.

 

TOP SLOAN FAUCET PRODUCTS

Here are the best water-saving faucets we found from Sloan. Keep in mind that these are the best products as of September 2019. New designs are constantly being created but this list can still be used as a baseline for comparison even as it becomes dated. We wouldn’t recommend any new product that doesn’t at least meet the performance standards of the products listed here. We will also add to this page our top choices purchased (best on the market at that time) as we build the Earthbag Village, Duplicable City Center, and other 6 sustainable village models. So expect this page to evolve for many years.

 

#1 :: SLOAN OPTIMA: EAF-350 (CODE #: 3335110)

SLOAN Optima: EAF-350 (Code #: 3335110), water-saving faucets, energy-saving faucets, bathroom faucets, bathroom sink, eco-faucets, sustainable faucets, infrared sensor faucets, timer faucets, green faucets, LEED compliant faucets, Highest Good housing, sustainable bathrooms, bathroom spigot, One Community GlobalWith Sloan ranked as our #1 sustainable company for faucets, it was certainly difficult to pick our top choice from their array of great, sustainable faucets. While Sloan has countless fantastic faucet options that would all be excellent choices, we did a deep dive paying close attention not only to the primary features but also the secondary and tertiary to deduce our #1. After much consideration, we have chosen the Sloan Optima: EAF-350 as our top choice. The greatest edge that this model had over the other Sloan models considered is that this 0.35 GPM model has several customizable features, namely the option to add the carbon offset feature. This boosted its sustainability points in our book. Additionally, this model is battery powered with a battery that has a service life of 3 years at the average usage of 8,000 cycles per month. This model also has an optional power harvesting feature which significantly extends the battery’s service life even further. The EAF-350 comes with a bi-stable magnetic solenoid valve for increased energy savings too. Lastly, we contacted them and confirmed that this faucet has a ‘timeout’ setting (how long it will run continuously with motion present) of 10 seconds and a ‘follow-up’ time (how often the sensor will check to see if a target is present) default set to 1 second and adjustable in the field to be between 0-10 seconds. This is fantastic for eliminating wasted water.

KEY FEATURES
  • Flow Rate: 0.35 GPM (1 Lpm)
  • Spray Type: Multi-Laminar (MLM)
  • Sensor Type: Infrared (IR)
  • Mounting Type: Single Hole
  • Power Supply: Battery (BAT)

#2 :: SLOAN OPTIMA: EAF-200 (CODE #: 3335164)

SLOAN Optima: EAF-200 (Code #: 3335164), water-saving faucets, energy-saving faucets, bathroom faucets, bathroom sink, eco-faucets, sustainable faucets, infrared sensor faucets, timer faucets, green faucets, LEED compliant faucets, Highest Good housing, sustainable bathrooms, bathroom spigot, One Community GlobalThe Optima EAF-200 is almost identical to the Optima EAF-350 that we voted #1. The main difference between the EAF-200 and the EAF 350 is that the 200 is hardwired power supply as opposed to the 350 being battery powered. The EAF-200 also appears to lack the bi-stable Magnetic Solenoid Valve. Since this valve provides energy savings for the EAF-350, and the EAF-200 lacks it, we ranked it lower. Other than this one feature, the EAF-200 is still a fantastic faucet with the all the other amazing features, certifications, and compliances as the EAF-350 (including the carbon offset option, which not many other Sloan faucets seem to have).

KEY FEATURES
  • Flow Rate: 0.35 GPM (1 Lpm)
  • Spray Type: Multi-Laminar (MLM)
  • Sensor Type: Infrared (IR)
  • Mounting Type: Single Hole
  • Power Supply: Hardwired Less Transformer (HLT)

#3 :: SLOAN OPTIMA: ETF-80 (CODE #: 3365321)

SLOAN Optima: ETF-80 (Code #: 3365321), water-saving faucets, energy-saving faucets, bathroom faucets, bathroom sink, eco-faucets, sustainable faucets, infrared sensor faucets, timer faucets, green faucets, LEED compliant faucets, Highest Good housing, sustainable bathrooms, bathroom spigot, One Community GlobalWhat’s unique about the ETF-80 is that the Sloan site actually lets you customize which compliances/certifications you want your faucet to be equipped with. In this regard it is one of the most customizable of the Sloan faucets because it lets the consumer prioritize which compliances and certifications are most important to them. While this is definitely a cool feature, it should be noted that all these Sloan faucets considered do come standard with many awesome and sustainable compliances and certifications, so it is hard to say how much of an edge this is. Other than that, it shares many of the same features as our #1 and #2 choice but lacks the carbon offset option, which is why it has ranked right below those models that do include it.

KEY FEATURES
  • Flow Rate: 0.5 GPM (2 LPM)
  • Spray Type: Multi-Laminar (MLM)
  • Sensor Type: Infrared (IR)
  • Mounting Type: 4″ Centerset
  • Trim Plate: 4″ (102mm) (4)
  • Power Supply: Box Transformer (BOX)
  • Temperature Mixer: Above Deck Mixer (ADM)
  • Finish: Polished Chrome (CP)
  • Factory Default Timeout: 30s
  • Factory Default GPC: 0.25

Compliances/Certifications vary based on customization..

#4 :: SLOAN OPTIMA: ETF-600 (CODE #: 3365773) / ETF-610 (CODE #: 3365166)

Sloan Optima ETF 600, Sloan Optima ETF 610, water-saving faucets, energy-saving faucets, bathroom faucets, bathroom sink, eco-faucets, sustainable faucets, infrared sensor faucets, timer faucets, green faucets, LEED compliant faucets, Highest Good housing, sustainable bathrooms, bathroom spigot, One Community GlobalThese two models are exactly the same except that the 610 has a Plug Adapter power supply while the 600 has a Box Transformer power supply. They are great faucets but have ranked #4 because they don’t have the carbon offset option that #1 and #2 have, and it is not as customizable as #3. With that said, it’s notable (and impressive) that all of our top Sloan faucets are very similar and we have only been able to differentiate them based on the intricate details like these that may or may not be super influential when making a purchasing decision.

KEY FEATURES
  • Flow Rate: 0.35 GPM (1 LPM)
  • Spray Type: Multi-Laminar (MLM)
  • Sensor Type: Infrared (IR)
  • Power Supply: Box Transformer (BOX)
  • Temperature Mixer: Back-Check Tee (TEE)
  • Factory Default Timeout: 30s
  • Factory Default GPC: 0.175

#5 :: SLOAN: SF-2100, 2200, 2300, 2400

Sloan: SF-2200 SF-2100 SF-2400 SF-2300, water-saving faucets, energy-saving faucets, bathroom faucets, bathroom sink, eco-faucets, sustainable faucets, infrared sensor faucets, timer faucets, green faucets, LEED compliant faucets, Highest Good housing, sustainable bathrooms, bathroom spigot, One Community GlobalThese four models are exactly the same to each other and almost exactly the same to #1-4 above. They have only scored lower than the ETF 600/610 because they have less compliances and certifications listed on their respective spec sheets than the 600/610 models. They are all still great products though that offer the same low .35 GPM flow rates, low-lead compliance, and LEED Credits for anyone seeking LEED certification like we are.

KEY FEATURES

#2 MOST SUSTAINABLE FAUCET COMPANY: TOTO

Toto was the second most sustainable company. What made them number two is that they had a less-updated version of their sustainability report and Sloan shared more about their products’ sustainable technology. It was a very close choice though. Like Sloan, Toto has a very comprehensive sustainability presence on their website. From company training to the principles and goals of Toto, they are very focused on the environment. The United Nations’ Sustainable Development Goals (SDGs) are integrated into their practices and they also have many sustainability related company goals they are seeking to achieve. Toto looks at six themes of global environmental activities: (1) Conserving water, (2) Preventing global warming, (3) Conserving natural resources, (4) Keeping the Earth clean, (5) Conservation of biodiversity, and (6) Contribution to local communities. They explain very comprehensively how they address all of these issues through their supply chain manufacturing of their products’ cradle-to-grave sustainable life cycle. Using their due diligence and legal compliance towards the environment, they are working towards being a highly sustainable company. They are also LEED v4 compliant and have earned many philanthropic awards over the years. The company also partners with Sustainable Minds, which is a software and information company that looks to integrate and innovate through environmentally-sustainable product design.

 

TOP TOTO FAUCET PRODUCTS

Here are the best water-saving faucets we found from Toto. Keep in mind that these are the best products as of September 2019. New designs are constantly being created but this list can still be used as a baseline for comparison even as it becomes dated. We wouldn’t recommend any new product that doesn’t at least meet the performance standards of the products listed here. We will also add to this page our top choices purchased (best on the market at that time) as we build the Earthbag Village, Duplicable City Center, and other 6 sustainable village models. So expect this page to evolve for many years.

 

#1 :: TOTO STANDARD ECOPOWER® FAUCET (TEL103 Series)

Toto Ecopower Faucet, water-saving faucets, energy-saving faucets, bathroom faucets, bathroom sink, eco-faucets, sustainable faucets, infrared sensor faucets, timer faucets, green faucets, LEED compliant faucets, Highest Good housing, sustainable bathrooms, bathroom spigot, One Community GlobalWe are a big fan of these Toto products because they use “Ecopower” rather than requiring a hardwired connection, batteries, etc. Ecopower “harnesses the energy of running water to power itself.” It should be noted that all of these Toto products had almost the exact same features on their spec sheets. The only differences that we were able to identify may not actually be very influential in consumer decision-making. Because each of these products are so similar, the most significant difference was cost. Therefore, since they all have the same features, those that offered these features at a cheaper price were ranked higher. Thus we have ranked the Toto Standard EcoPower Faucet as #1 because it is around 30%+ cheaper than other models with identical features. It has a flow rate of 0.35 GPM, uses the flow of water to power itself (Toto’s “EcoPower” — no need for external power source), and is equipped with an infra-red sensor to ensure water is only released when a user activates it. Additionally, the Standard has Vandal resistant aerator housing, which only one other model seems to have (the Libella™ models). Thus since all the top Toto products are almost identical, and the Standard is significantly cheaper, we have ranked the Standard #1.

#3 :: HELIX™ LINE OF FAUCETS

This line of faucets are described as “designed for high-traffic spaces.” Seeing as the key features appear to be exactly the same as the standard also, this must be in reference to the body style. The prices of the assorted models range from about $800-950. See the Faucet Spreadsheet for feature specifics and options.

#3 MOST SUSTAINABLE FAUCET COMPANY: KOHLER

The third most sustainable company was Kohler. This company was chosen for the third spot because they didn’t have the most updated sustainability report, but they still had an abundant sustainability presence on their website. They had many goals towards their commitment to the environment through working towards a net-zero environmental impact by 2035. Kohler also looks to the United Nations’ SDGs and has many community outreach programs focused on water conservation and projects that they have created around the nation. Similar to Sloan, they also have adopted Kohler’s Environmental Product Declarations (EPDs) that create a level of transparency by labeling the products’ life cycle through the entire supply chain. They are also a LEED certified company. A very impressive current initiative they have is a solar panel farm in South Carolina that has more than 4,000 solar panels that produce 1,000 kilowatts of power and offsets the amount of power supplied by their local utility by 9%. That is not a huge contribution, but it is something that shows that they are more committed than many to being a sustainable company. They have many partners, some to note are: WaterSense EPA, Habitat for Humanity, Harvard Center for Climate, Health, and Global Enterprise, The Water Council, and Rotary International. For the full list of Kohler’s partners, take a look at the Benchmarking Tab on our research spreadsheet.

Kohler K-7516-CP Eco-Faucet, water-saving faucets, energy-saving faucets, bathroom faucets, bathroom sink, eco-faucets, sustainable faucets, infrared sensor faucets, timer faucets, green faucets, LEED compliant faucets, Highest Good housing, sustainable bathrooms, bathroom spigot, One Community GlobalAll of the Kohler options listed below have Kohler’s Insight Technology, which is described on their website as “… an adaptive infrared sensor that gathers and analyzes the surrounding area upon installation. After recording these details, Insight calibrates the sensor to filter false triggers and optimize the faucet’s operation.” We like that all these faucets will gather data to decrease the number of times in which the sensor is mistakenly activated. We chose the K-7514 and K-7516 models as our #1 models because they both have a key feature that sets them apart from the other brands, namely that they are the only ones from these top products that are powered by a 30-year hybrid energy cell. They are both .5 GPM faucets though, not as conservation-minded as the .35 GPM faucets above.

KEY FEATURES
  • 0.5 GPM (1.9 l/min) flow rate
  • Factory set 30 second max. continual run cycle
  • Vandal-resistant aerator
  • 24″ (610 mm) flexible supply hoses for easy installation
  • 5-5/16″ (135 mm) spout reach
  • Less drain
  • Less temperature mixer
  • Powered by the 30-year hybrid energy system
  • Insight™ adaptive infrared technology
  • Waterproof shroud protects electronic components
  • Water-saving vandal-resistant 0.5 GPM aerator

#2 :: KOHLER K-7514-CP

Kohler K-7514-CP Eco-Faucet, water-saving faucets, energy-saving faucets, bathroom faucets, bathroom sink, eco-faucets, sustainable faucets, infrared sensor faucets, timer faucets, green faucets, LEED compliant faucets, Highest Good housing, sustainable bathrooms, bathroom spigot, One Community GlobalThe KOHLER hybrid energy system is a first-of-its kind 30-year power solution for touchless faucets. When combined with Insight Technology, this system provides an environmentally-friendly, virtually maintenance-free electronic faucet. We ranked this faucet below the 7516 model because it wasn’t listed as having a “Factory set 30-second maximum continual-run cycle.”

KEY FEATURES
  • 0.5 GPM (1.9 l/min) flow rate
  • Above-counter valve for easy installation and maintenance
  • Vandal-resistant aerator
  • 5″ (127 mm) spout reach
  • Without temperature mixer
  • Includes 30-year Hybrid Energy Cell
  • Less drain
  • Powered by the 30-year hybrid energy system
  • Insight™ adaptive infrared technology
  • Waterproof shroud protects electronic components
  • Water-saving vandal-resistant 0.5 GPM aerator

#3 :: KOHLER “PURIST” K-T11837-CP

Purist K-T11837-CP Eco-Faucet, water-saving faucets, energy-saving faucets, bathroom faucets, bathroom sink, eco-faucets, sustainable faucets, infrared sensor faucets, timer faucets, green faucets, LEED compliant faucets, Highest Good housing, sustainable bathrooms, bathroom spigot, One Community GlobalThe Purist K-T11837-CP is definitely very similar the the #1 option with the main difference being that this one is hardwired rather than powered by a long-lifetime energy cell. The main reason it has ranked lower is because it does have the option to be left on continuously for about 30 seconds, which could be a hindrance to water conservation if abused. It is unclear if this is setting is able to be customized. Also it should be noted that this is the only Kohler faucet from our top selections that has Safe Drinking Water Act (SDWA- Low Lead) compliant in spec sheet. This is not to say that the others do not have this compliance, but this is the only one that explicitly mentions it.

KEY FEATURES
  • 0.5 gal/min (1.9 l/min) flow rate
  • This is trim set only. It requires valve kit to complete the faucet
  • Vandal-resistant aerator
  • 8-1/4″ (210 mm) spout reach
  • Less drain
  • Safe Drinking Water Act (SDWA- Low Lead) compliant
  • On demand on and off. Valve kit is factory set to 30 second max. continual run cycle if it turned on continuously
  • Valve kit has electronic Insight™ Sensor Technology for accurate and consistent activation
  • This trim set can be used with 11830-NA (Hybrid power) wall mount valve or 11843-NA (AC Power) wall mount valve

#4 MOST SUSTAINABLE FAUCET COMPANY: GROHE

GROHE is the fourth most sustainable company on this list. Of the companies that had a sustainability report, theirs was the least updated – from 2015/2016. They are, however, a very sustainable company that has pushed forward with many sustainable innovations for their products and that is why they are ranked at number four. This company takes a comprehensive look at how they can be sustainable through their products and through the workplace. They are committed through their products, processes of creating the products, employees being trained, taking their customers safety and health into consideration with the products, suppliers and service producers of where they get their raw materials for their products, and their level of social responsibility. This company has created “GROHE’s Sustainability Policy,” which looks at policies that consist of principles and guidelines for sustainable action. They have also created the GROHE EcoJoy Technology line that are products specifically designed to conserve water and energy. And on their website they offer a water/energy calculator that computes the costs and benefits of each product. They are also under the LIXIL Net Zero Program that looks to offset greenhouse gas emissions. LIXIL is a Japanese building and housing company that, over the years, has expanded internationally and acquired many companies such as GROHE and American Standard (which is also in this list, but later on).

 

TOP GROHE FAUCET PRODUCTS

Here are the best water-saving faucets we found from GROHE. Keep in mind that these are the best products as of September 2019. New designs are constantly being created but this list can still be used as a baseline for comparison even as it becomes dated. We wouldn’t recommend any new product that doesn’t at least meet the performance standards of the products listed here. We will also add to this page our top choices purchased (best on the market at that time) as we build the Earthbag Village, Duplicable City Center, and other 6 sustainable village models. So expect this page to evolve for many years.

 

#1 :: GROHE EUROSMART COSMOPOLITAN E AND GROHE EUROPLUS E

Grohe Eurosmart Cosmopolitan E, Grohe, Europlus E eco-faucet, water-saving faucets, energy-saving faucets, bathroom faucets, bathroom sink, eco-faucets, sustainable faucets, infrared sensor faucets, timer faucets, green faucets, LEED compliant faucets, Highest Good housing, sustainable bathrooms, bathroom spigot, One Community GlobalLike the other companies, the GROHE top-of-the-line faucets were all very similar to each other. All of the GROHE products evaluated have a battery service life of up to seven years (150 cycles/day). Additionally, they are all easy to switch between lithium battery (6 V) and mains supply (230 V). They also have safety shut-off after 60 seconds, adjustable between two and 420 seconds. They also come standard with a temperature mixer. What sets the Eurosmart Cosmopolitan E and the Europlus E models above the rest is that they have the option to add the GROHE Powerbox. The GROHE Powerbox harnesses the flow of water as an energy supply. This is how it works: “A turbine in the power box is driven by the water supply each time the fitting is operated. This converts kinetic energy into electrical energy and stores it to operate the infrared electronics. Using the generator for as little as 60 seconds delivers enough electricity to power the fitting for 24 hours.” The Powerbox also has a service life of 10 years, this helps reduce required maintenance and lowers operating costs.

KEY FEATURES
  • Faucets group I (DIN 4109)
  • Flow pressure min. 0.5 bar/recommended one to five bar
  • Flow rate 5.7 l, pressure-independent
  • Hot water stop-valve
  • Cleaning mode via sensor
  • Plug and play: easy to switch between lithium battery (6 V) and mains supply (230 V)

  • Battery voltage indicator through sensor
  • Individual setting for automatic flushing and thermal disinfection
  • Protection against scalding – stops automatically when a hand approaches
  • Safety shut-off after 60 seconds, adjustable between two and 420 seconds
  • Program selection (seven programs), manual or remote control
  • Battery compartment in non-visible area below the wash basin for ease of maintenance
  • Can be combined with Grohtherm Micro
  • Vandalism-protected rotation lock (can be retrofitted)

#2 :: GROHE ALLURE E AND ESSENCE E

Grohe Allure E, Grohe Essence E eco-faucet, water-saving faucets, energy-saving faucets, bathroom faucets, bathroom sink, eco-faucets, sustainable faucets, infrared sensor faucets, timer faucets, green faucets, LEED compliant faucets, Highest Good housing, sustainable bathrooms, bathroom spigot, One Community GlobalThe Allure E and Essence E are also really great faucet options from Grohe. Their features are almost exactly identical to each other, with the main difference being the body style. They have a flow rate of 0.5 GPM and are equipped with a sensor that can be configured to shut off as quickly as 2 seconds after a user is no longer detected. They have ranked below the Europlus E and Eurosmart Cosmopolitan E because the Allure E and Essence E are not compatible with the Grohe Powerbox.

KEY FEATURES
  • Faucets group I (DIN 4109)
  • Flow pressure min. 0.5 bar/recommended one to five bar
  • Flow rate 6 l; pressure-independent
  • Hot water stop-valve

#5 MOST SUSTAINABLE FAUCET COMPANY: MOEN

The fifth most sustainable company is Moen. This company is ranked number five because it did not have as robust of a sustainability presence on their website as the other companies observed. Of course, they are still a sustainable company because they made the list, but when being ranked with the chosen companies in this list, they were not the top choice. They do have many initiatives that are noteworthy, such as how all of their faucets are certified to meet the WaterSense EPA standard criteria by using up to 32% less water than a conventional faucet. Their most recent waste reduction and recycling initiatives include recycling nearly 82% of waste from their manufacturing process and almost 20% of all water used. Also, more than 74% of Moen’s production (in dollar terms) was made from raw materials that included some amount of recycled material. In addition to this, recycling more than 13 million pounds of metal, 6.5 million pounds of cardboard, 3.8 million pounds of solid waste, only using recycled paper and soy-based inks for copies.

 

TOP MOEN FAUCET PRODUCTS

Unfortunately the Moen website only offered a few faucet options equipped with sensors, all three of which were kitchen faucets. Thus all the bathroom faucet options have no sensors and would not be able to be set to turn off after a specified amount of time. Additionally, we were not able to find any models that were below 1.0 GPM. Our criteria specified that in order to be considered sustainable the faucet would need to be below 0.5 GPM, or if not, have the ability to add a water saving nozzle. Moen did not meet our standards as it was over 0.5 GPM and did not have sensors, therefore no Moen products were considered.

 

#6 MOST SUSTAINABLE FAUCET COMPANY: AMERICAN STANDARD

The sixth most sustainable company is American Standard. Being a classic faucet company that was formed from Crane Plumbing, a company that was founded in 1906, it is surprising that American Standard would be ranked last on this list. They came short in many different sustainability and environmental areas. For instance, they did have a sustainability section on their website, but it was very small and insignificant. It didn’t explain a lot of what they are doing in regards to initiatives or goals through sustainable measures. Also, there was no specific sustainability report found for this company, which shows that American Standard does not have a commitment to providing a transparent report for its stakeholders and the public to see all that they are doing in the sustainability and environmental arena. The only impressive aspect regarding sustainability that we could find on their website or for their products was water-savings calculators to compute how much you could save commercially and residentially for each product on their website. Also, there were no sustainability partners listed on their website, showing that they are not interested in collaborating with other sustainable organizations for various initiatives, programs, and/or goals. Even though they fell short of the others though, we included them here at the end because we still thought they were sustainable and environmentally conscious enough through good business practices and building sustainability into their workplace and overall company. Just not to the extent that the other five companies were.

 

TOP AMERICAN STANDARD FAUCET PRODUCTS

Being the lowest-ranked company on our list, we only included one water-saving faucet from American Standard. This was their best product as of September 2019. New designs are constantly being created but the product below can still be used as a baseline for comparison even as this page becomes dated. We wouldn’t recommend any new product that doesn’t at least meet the performance standards of the product below though. We will also add to this page our top choices purchased (best on the market at that time) as we build the Earthbag Village, Duplicable City Center, and other 6 sustainable village models. So expect this page to evolve for many years.

 

#1 :: AMERICAN STANDARD 702B305.002 and 7025303.002

#2 :: MELO AUTOMATIC SENSOR FAUCET

Melo Automatic Sensor Faucet, sustainable sinks, sink sustainability, green living, eco-living, Highest Good housingThe Melo Automatic Sensor Faucet was chosen as our #2 choice because it has an adjustable time option, but we don’t consider this as efficient as our auto-off choice above. Like all the choices here, this faucet is completely motion detection operated and the adjustable factory setting comes set to 30 seconds. We liked the “smart” aspect of this faucet, using a sensitive sensor with infrared AI Smart-Chip for a non-dripping design and the ability to self-adjust for its best detection zone as per the color and shape of your lavatory. This faucet can be used commercially or for residential use, has a 360 degree rotating neck, and is ADA compliant.

#3 :: SLOAN OPTIMA SOLIS SOLAR-POWERED SENSOR-ACTIVATED FAUCET

Sloan Optima Solis Solar Powered Sensor Activated Electronic Faucet, sustainable sinks, sink sustainability, green living, eco-living, Highest Good housingWe chose the Sloan Optima Solis Solar-powered Sensor-activated Faucet as our #3 choice because it works with ambient light, like a solar-powered calculator. Its integrated power plant storage cell transforms light from any source into electrical energy. This helps to achieve LEED credit points by conserving energy and water, making it ideal for “green” building. It regulates water flow using an electronic sensor that automatically turns water on/off and has an integral temperature control for hot or cold water operation with integral spout temperature mixer. It does not have an adjustable time or sensor range option though. It’s also from the #1-ranked company identified during our sustainability benchmarking process.

#4 :: KOHLER K-13468-VS TOUCHLESS FAUCET

Kohler Geometric Single-Hole Touchless Faucet, sustainable sinks, sink sustainability, green living, eco-living, Highest Good housing The Kohler K-13468 touchless faucet is #4 on our list because it comes standard with a .5 GPM flow rate, a 30-second max continual-run cycle, and adaptive infrared technology that gathers and analyzes the surrounding areas upon installation, records the details, and then calibrates the sensor to filter false triggers and optimize the faucets operation. Kohler has also been building products since 1873! A waterproof shroud protects electronic components and it is made with a vandal resistant aerator. One possible downside to this faucet is that it requires an AC power supply. It’s also from the #3-ranked company identified during our sustainability benchmarking process.

KEY FEATURES
  • Requires an AC power supply
  • 0.5 gal/min (1.9 l/min) flow rate
  • Factory set to 30 second max continual-run cycle

#5 :: FYEER FN0103S AUTOMATIC TOUCHLESS-SENSOR FAUCET

Fyeer Automatic Touchless Sensor Bathroom Faucet, sustainable sinks, sink sustainability, green living, eco-living, Highest Good housingFyeer has been designing quality kitchen, bath, and bar faucets for more than 20 years and the Fyeer automatic sensor touch-free faucet is no exception. The FN0103S Automatic Touchless-sensor Faucet is #5 on our list because it comes standard with a 2 GPM flow rate and a factory-set 60-second time out for water flow. These mean more water used and less sustainability (and definitely doesn’t qualify for LEED points), but may be desirable settings for others. So we’ve included this faucet here mainly to point out these features as something to be aware of and consider – and keeping in mind that a Faucet Accessory can probably be attached and fix this flow rate issue. Like several of the ones above, the sensor is powered by a 4-pack of AA batteries and the company says these will last for around 7,000 uses, or about 2 years for daily use. AC/DC power connections are available as an option too. It is ADA complaint.

KEY FEATURES
  • It is an automatic sensor touch-free faucet
  • 2 GPM flow rate – may be correctable with one of these Faucet Accessories
  • Factory-set 60-second time out for water flow
  • Sensor batteries last for around 7,000 times
  • AC/DC power is an alternate option if batteries aren’t desired
  • ADA Compliant
PROS/CONS COMMENTS
  • We couldn’t easily find the spec sheet, so it’s not included in the links below
  • “One year later, still working great!”
  • “Great product”
  • “Low price, looks great, performs well”
  • “No need for expensive names here”
  • “Unit looks good”
  • “It’s magic”

BEST WATER-SAVING FAUCET
ACCESSORIES WE COULD FIND

Highest Good society, fulfilled living, enriched life, enriching life, living to live, how to live an enriched life, keeping it all running, sustainable living, social architecture, fulfilled living, thriving, thrivability, emotional sustainability, the good life, a new way to liveOur research also included identifying the best faucet accessories. These are great for upgrading your current faucet and, in many cases, can even be combined with the faucet recommendations above. While we’re talking accessories, it’s helpful to mention that the easiest way save water is to turn it off when not using it. Meaning turn it off while brushing teeth, soaping hands, etc. rather than letting it run. In most households this will save even more water than upgrading your faucet. Upgrading your faucet AND turning the water off when not in use saves even more.

 

#1 :: NEOPERL® MIKADO WATER-SAVING FAUCET AERATOR INSERT

Neoperl® Mikado Ultimate Low Flow Aerator, water-saving faucet attachment, eco-attachment, sustainable living, sustainable water, best water saving faucet insert, faucet insert, Highest Good housingThe NEOPERL® Mikado Water-Saving Faucet Aerator Insert was chosen as our #1 choice because it uses the least amount of water at an impressive 0.35 GPM flow rate and only replaces the aerator part of a faucet. This means saving water and materials because you don’t end up throwing away (or indefinitely storing) your old faucet-aerator housing. This aerator also offers a distinctive flow pattern that the company says “will add elegance to any bathroom.” The replacement aerator fits most faucets with 15/16 in. -27 or 55/64 in. -27 housings and comes in a pack of 6 for $9.32 through Amazon.

KEY FEATURES
  • Impressive .35 GPM flow rate
  • Saves waste by only replacing the inside of the faucet housing, not the housing and the insides
  • More affordable than most because it uses less materials by only replacing the insides
  • Fits most faucets with 15/16 in. -27 or 55/64 in. -27 housings
  • A distinctive flow pattern that “will add elegance to any bathroom”
  • Dual-thread system accommodates both male and female faucet threads
PROS/CONS COMMENTS
  • “Amazing!”
  • “Saves so much water”
  • “Affordable and easy to use”
  • “Five star rating”

#2 :: NEOPERL® MIKADO ULTIMATE LOW FLOW

The NEOPERL Mikado Water-Saving Faucet Aerator Insert, water-saving faucet attachment, eco-attachment, sustainable living, sustainable water, best water saving faucet insert, faucet insert, Highest Good housingThe NEOPERL® Mikado Ultimate Low Flow also provides a 0.35 GPM flow rate, and is thus our #2 choice. Like the insert above, it also “turns the water stream into an eye-catcher when washing your hands. Its extraordinary, grid-like spray pattern – formed by individual water jets – creates a surprisingly clear and harmonious effect in its delicate design idiom. Given that owing to its form the spray loses density as it moves downwards, the force of the jets ranges from pleasantly soft to vigorously massaging. The visual effects of the water stream turn washing your hands into an enchanting experience.” It is also lead free and complies with the reduction of lead in the Drinking Water Act.

KEY FEATURES
  • Impressive .35 GPM flow rate
  • Beautiful and unique flow pattern
  • Pressure compensating design
  • Lead free
  • Variable density spray providing soft to vigorous water
  • Dual-thread system accommodates both male and female faucet threads
PROS/CONS COMMENTS
  • “Extremely PLEASED!”
  • “Nice flow and pattern”
  • “Cool, but very low flow”
  • “Five Stars”
  • “Saves Water but Still an Effective Faucet”

#4 :: NEOPERL MULTIPLE LAMINAR STREAM BATHROOM FAUCET AERATOR

NEOPERL Multiple Laminar Stream Bathroom Faucet Aerator, water-saving faucet attachment, eco-attachment, sustainable living, sustainable water, best water saving faucet insert, faucet insert, Highest Good housingThe NEOPERL® Multiple Laminar Stream Bathroom Faucet Aerator has a flow rate of 0.5 GPM and is pressure compensating. This was our #4 choice because the NEOPERL company does not have the same impressive history of sustainability that Niagara does. Other than that though, it is pretty much tied with our #3 choice. The mini-shower spray pattern it provided may also be preferable for some, it offers full coverage and an even and consistent flow without quite as much force as the “needle spray” of the Niagara.

KEY FEATURES
  • Flow rate of 0.5 GPM
  • Pressure compensating
  • Provides a non-splashing, non-aerated spray
  • Medium-pressure (less than “needle spray”) mini-shower spray pattern
  • Dual-thread system accommodates both male and female faucet threads
PROS/CONS COMMENTS
  • “I actually like these…fits inside existing spouts.”
  • “Good Product and Purchase!!!”
  • “Perfect”
  • “Four Stars”
  • “Water-money savings”

#5 :: ALTERED NOZZLE

Altered Nozzle, 98 percent water savings, water-saving faucet attachment, eco-attachment, sustainable living, sustainable water, best water saving faucet insert, faucet insert, Highest Good housingThe Altered Nozzle has a “Mist Mode” that allows it to save up to 98% of water, making it the most conservation-minded option for washing hands, brushing teeth, etc. It also has a “Save Mode,” which has savings up to 85% of water if someone needs more to fill a glass, pots, or pans. The reason this is our #5 choice though is because our Executive Director purchased this nozzle as part of the original Kickstarter and found it impractical. It works well enough for lightly wetting a washcloth or your toothbrush, but poorly to rinse a toothbrush or fill a glass. Turning it to “Save Mode” fixes these issues but it was difficult to twist back and forth. “Mist Mode” also made things around our sink wet because the mist was so fine, so we tended to leave it in “Save Mode.” After 6 months we switched to the Niagara Conservation 0.5 GPM Low-flow Dual-thread Faucet Aerator that turned out to be #3 on this list. It isn’t as conservation-minded of a choice as this one but we turn our water off between uses, and use so little sink water already, that we rationalized skipping just one shower on a day at home would more than offset the difference. We did that when we switched. 🙂

KEY FEATURES
  • The most environmentally conscious option
  • Has ‘The Mist Mode’ and the ‘Save Mode’ options on this model
  • On ‘The Mist Mode’ it saves up to 98% of water when used
  • On the ‘Save Mode’ it saves up to 85% of water when used
PROS/CONS COMMENTS

  • “They also take a good amount of time washing their hands”
  • “Nice snug fit. No leaking. This is awesome.”
  • “Hard to switch from Mist to Save mode.” – Community Pioneer Jae
  • “Mist mode makes the areas around my sink wet.” – Community Pioneer Jae
  • “Mist mode has extremely limited uses.” – Community Pioneer Jae
  • “Save mode pressure is too high, makes a mess.” – Community Pioneer Jae

FREQUENTLY ANSWERED QUESTIONS

Q: What is GPM and LPM?

GPM is gallons per minute and LPM is liters per minute.

Q: What does OEM mean?

OEM stands for Original Equipment Manufacturer.

Q: What is the difference between a timeout setting and a follow-up setting?

The timeout setting is for the maximum amount of time the faucet will dispense water with a target present. If you wanted a faucet with a timeout setting of ‘0’, it would not dispense any water. The follow-up time is how often the sensor will check to see if a target is present so that it continues to provide water.

Q: Where will you be posting your continued research?

We’ll create individual pages with testimonials and YouTube links with more details. We will then link to all of those pages from this page.

Q: Was One Community paid or incentivized in any way to choose the products we chose?
