FAQs

Contaminants

[H4] What contaminants do Elkay residential water filtration systems reduce?
Elkay filters reduce lead, chlorine taste and odor, particulates, cysts, pharmaceuticals, and select PFAS chemicals. Some models also reduce microplastics. Always review the product specification sheet for detailed contaminant reduction claims.
[H4] Does Elkay residential filtration remove PFAS?
Yes. Select Elkay filters are tested to reduce PFAS compounds like PFOS and PFOA. Look for models featuring Elkay Pro Filtration™ or those meeting NSF/ANSI 53 and 401 standards.
[H4] Do Elkay residential filters remove lead?
Yes. Elkay filters certified to NSF/ANSI 53 standards reduce lead from tap water, helping protect families, especially in older homes with aging pipes.
[H4] What contaminants do Elkay filters remove?
Elkay filters are certified to reduce lead, chlorine taste and odor, and select filters also remove microplastics, cysts, and PFAS chemicals.
[H4] Are Elkay filters NSF certified?
Yes, Elkay filtration systems are tested and certified to NSF/ANSI 42, 53, and 401 standards, ensuring reliable performance against harmful contaminants.
[H4] What are PFAS? What are forever chemicals? Where do they come from?
Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonate (PFOS) are the two most prevalent forever (PFAS) chemicals used to make nonstick cookware, personal care products and many everyday items. When the remains of these products are discarded, PFOA/PFOS leak into our soil and water because they don’t degrade easily, which means we end up ingesting these harmful chemicals.
Total PFAS: PFAS are long-lasting synthetic chemicals used in everyday products, such as personal care, nonstick cookware and water-repellant clothing, that break down very slowly. Due to their widespread use, PFAS end up in the environment — in our water, the air, fish, soil and food. PFAS have even been found in human and animal blood. Scientific studies have shown that exposure to some PFAS may be linked to harmful health effects, such as cancer, fertility issues and child development delays. But Elkay offers an Elkay Pro Filtration filter that is tested and certified to NSF/ANSI 53 to reduce Total PFAS.* See performance data sheet for complete details. Source: *epa.gov/pfas/our-current-understanding-human-health-and-environmental-risks-pfas
[H4] Lead
More than 9 million water service pipes in the U.S. are made of lead, and when they corrode, lead can leach into the water. Because you can’t smell, see or taste lead, it’s not easily detectable and harmful, especially to children. Lead exposure can damage the brain, spinal cord and nerves, cause learning disabilities and more. Source: EPA.gov
[H4] Cysts
Cysts are parasites that enter drinking water from human and animal waste, which can lead to gastrointestinal illness such as dysentery, vomiting and cramps. Source: EPA.gov
[H4] Sediment & Class I particulate
Sediment comes from sand, rocks and minerals, or may consist of organic particles of plants and microbes. Not only is sediment undesirable to consume, but too much of it could reduce flow rate.
If you live in an area where sediment pollution is high, consider adding one of our universal sediment prefilters for a two-stage filtration process. Not sure if you live in a high-sediment area? Stay up to date on your state’s water quality or visit your city’s public water site. Source: Water Systems Council
[H4] Turbidity
Turbidity is the cloudiness or haziness of water, which is caused by particles that are generally too small to see. High turbidity means water appears very cloudy or muddy, and can also be an indicator of water quality, suggesting the presence of pollutants and contaminants. Turbid water looks dirty and is unappealing, which may deter people from drinking it. Elkay Pro Filtration filters are tested and certified to NSF/ANSI 53 to reduce turbidity in drinking water.
[H4] Asbestos
Due to its fiber strength and heat resistance, asbestos was used in building construction for insulation, in pipes and cement, and as a fire retardant. While asbestos is banned now, it may be present in older homes and buildings. As these buildings age and deteriorate, and as asbestos-containing material is discarded during demolition and reconstruction of old homes, asbestos fibers may be released into waterways. Exposure to asbestos fibers increases your risk of developing lung disease. Asbestos may be found in textured paint, coated hot water and steam pipes, attic and wall insulation, vinyl floor tiles, roofing and more — but can ultimately end up in the water we drink. Source: https://www.epa.gov/asbestos/learn-about-asbestos#asbestos
[H4] Antiscalant
Antiscalant helps minimize filter maintenance, keeping yours working effectively.
[H4] Chlorine taste & odor
Water can be contaminated at the source and as it travels through piping, which is why many water companies add chlorine as a disinfectant. However, it can leave an undesirable taste and smell. Source: CDC.gov
[H4] What are microplastics? Where are they found?
Plastic is found in countless everyday items, such as obvious items like disposable plastic containers, but also in car tires and even laundry detergent. This plastic ends up in the environment and breaks down or weathers into smaller plastic particles. These microplastics that are smaller than 5 millimeters end up everywhere — in our waterways, seafood, milk, chicken, the list goes on. This means we could be ingesting tiny bits of plastic daily.
[H4] How to minimize microplastic consumption?
Although it’s almost impossible to avoid microplastics because they’re everywhere, there are ways to minimize exposure. Instead of plastic shopping bags and single-use plastic bottles, opt for tote bags and reusable water bottles. Fill reusable bottles with filtered water — Elkay filters are tested and certified to NSF/ANSI 401 to reduce microplastics. Heat food in glass containers instead of plastic ones, which can release millions of microplastic particles in your food.

WaterSentry Filters

[H4] Are Elkay filtration systems compatible with all Elkay bottle filling stations?
Most Elkay filters are designed to fit standard Elkay bottle filling station models. Always check the model number for compatibility.
[H4] Where can I buy Elkay replacement filters?
Replacement filters are available directly on Elkay.com, through subscription, or via authorized distributors.
[H4] How do I know when to change my Elkay filter?
Many Elkay bottle filling stations have a filter status light (green, yellow, red). Red indicates it's time to replace the filter.
[H4] How do I know what replacement filter to order for my Elkay bottle filling station, cooler or fountain?
Click here to use our Filter Selection Tool to find your filter.
[H4] What kind of filter is used in Elkay filtered bottle filling stations, outside the Elkay Pro Filtration collection?
Our WaterSentry® filters are carbon block filters with a polypropylene prefilter that is tested and certified to NSF/ANSI 42 and 53 for lead, chlorine taste and odor. We offer a 3,000-gallon filter (51300C) for all our original bottle filling stations and a 6,000-gallon high-capacity filter (51600C) specifically for our enhanced bottle filling stations. We also offer a 2,250-gallon filter (71300C) for our enhanced bottle filling stations that reduces PFAS (PFOA/PFOS), two prevalent PFAS chemicals.
[H4] What do Elkay WaterSentry Filters reduce from water?
Both the WaterSentry 51300C and the 51600C reduce lead, Class 1 particulates, cysts microplastics, and chlorine taste and odor. The 71300C reduces PFAS (PFOA/PFOS), lead, Class 1 particulates, cysts and chlorine taste and odor.
[H4] How long does a filter last?
The 51300C filter is rated for 3,000 gallons which is approximately 19,200 20-oz. bottles.
The 51600C filter is rated for 6,000 gallons which is approximately 38,400 20-oz. bottles.
The 71300C filter is rated for 2,250 gallons which is approximately 1,400 20-oz. bottles.
Actual filter life depends on usage. We recommend changing the filter at least once a year.
[H4] What do the lights mean on the bottle filling station? How do I know if the water is safe to drink?
Green LED: Your filter is working.
Yellow LED: Your filter should be changed.
Red LED: Filter has reached end of life and may no longer be effective.
Flashing Red: Only applies to P-SKU’s.
[H4] How do I reset the visual filter monitor light?
Enhanced bottle filling stations include FillSafe™ recognition, a feature that detects when a new Elkay filte
