    The Water You Want. That's Elkay.

    Filtered Water Makes a Difference

    What’s not in your drinking water is just as important as what’s in it. When you drink from an Elkay filtered bottle filling station, cooler or fountain, healthy hydration is at hand. Here’s a look at what our water filters reduce from incoming water and why it matters to your good health.




    Filter Panel

    Cut Your Filter Replacement Time in Half

    Whether you have one water delivery unit or 15, our EZ Filter Maintenance Kit can help make filter changes faster, so you can focus on other things while providing cleaner water in your facility. Cut your filter replacement time in half with this retrofit cooler wrapper that features an integrated side panel that gives quick access to the filter and water shut-off valve. No more removing the entire wrapper to change the filter. Kit is the ideal solution for schools, hospitals and other busy commercial spaces.



    Our filters are tested and certified to NSF standards to reduce harmful contaminants. Different Elkay filters reduce different contaminants (see individual product pages for details). Here’s a look at what our various filters reduce and why it’s important.    



    Lead can enter water through corroded plumbing materials. It’s undetectable by taste, sight or smell. In children, lead exposure has been linked to damage to the central and peripheral nervous system, learning disabilities and more. 



    Cysts enter drinking water from human and animal waste, and can lead to gastrointestinal illness such as dysentery, vomiting and cramps.



    Water can be contaminated at the source and as it travels through piping. Many water companies add chlorine as a disinfectant. It can leave an undesirable taste and smell. 

    Sediment and Particulate

    Sediment and Particulate

    Sediment comes from sand, rocks and minerals, or may consist of organic particles of plants and microbes. They can take on a cloudy and unappealing look in water. 



    Why NSF/ANSI Standards Matter

    IAPMO Logo

    Engineered to meet the high-quality standards written by NSF International, Elkay water filters are tested and certified to NSF/ANSI 42 for the reduction of chlorine taste and odor, as well as Class I particulates.* 

    Similarly, our water filters are tested and certified to NSF/ANSI 53 for the reduction of both lead and cysts. The NSF/ANSI certifications ensure that each sip of water — whether from Elkay’s ezH2O® bottle filling stationswater coolers, drinking fountains or water dispensers — is not only refreshing but also cleaner and healthier.

    Our filters are specifically designed to fit and have been certified for use within Elkay drinking water products. 

    *Certifier and contaminants reduced vary. See individual filter product page for more information.

    Lead often enters water when plumbing materials corrode. It’s undetectable by taste, sight or smell. In children, lead exposure has been linked to damage to the central and peripheral nervous system, learning disabilities, shorter stature, impaired hearing, and impaired formation and function of blood cells.

    Adults exposed to lead can suffer from cardiovascular effects, increased blood pressure and incidence of hypertension, decreased kidney function and reproductive problems in both men and women.




    Two types of common types of cysts are Giardia lamblia and Cryptosporidium. They enter drinking water from human and animal waste, and can lead to gastrointestinal illness such as dysentery, vomiting and cramps. They are not life threatening if treated.  




    Water comes from many sources, including lakes and wells. It can be contaminated at the source. It can also be contaminated with germs as it travels through miles of piping. To prevent contamination, water companies add a disinfectant — usually either chlorine or chloramine — that kills disease-causing germs such as SalmonellaCampylobacter and norovirus. Though chlorine is used as a disinfectant, it can leave an undesirable taste and smell. 



    Sediment and Particulate

    Sediments are naturally occurring particles that develop as earth materials. They break down through weathering and erosion. Sediment comes from sand, rocks and minerals, or may consist of organic particles of plants and microbes. They can take on a cloudy and unappealing look in water.

    What kind of water filter is used in Elkay bottle filling stations?

    Our WaterSentry® filter is a carbon block filter with a polypropylene prefilter that is rated to NSF 42 and 53 for lead, chlorine taste and odor. We offer a 3,000-gallon filter (51300C) for all our bottle filling stations and a 6,000-gallon high-capacity filter (51600C) specifically for our enhanced bottle filling stations.


    What does the filter remove from the water?

    Both the WaterSentry 51300C and the 51600C reduce lead, cysts, sediment/particulate and chlorine taste and odor.


    How long does a filter last?

    Our WaterSentry 51300C filter is rated for 3,000 gallons which is approximately 19,200 20-oz. bottles. Our WaterSentry 51600C filter is rated for 6,000 gallons which is approximately 38,400  20-oz. bottles. Actual filter life depends on usage. We recommend changing the filter at least once a year.


    What do the lights mean on the bottle filling station? How do I know if the water is safe to drink?

    The LED lights on the bottle filling station indicate the filter status.

    Green: Filter is functioning between 0-80% of usable filter life.

    Yellow: Filter has reached 80% of usable life and will need to be replacement shortly.

    Note: When the status is green or yellow, the bottle filler is providing cleaner and fresher drinking water. 

    Red: Filter has reached 100% of usable life and should be replaced promptly.


    How do I reset the visual filter monitor light?

    Enhanced bottle filling stations include FillSafe™ recognition, a feature that detects when a new Elkay filter is installed and automatically resets the filter monitor light from red back to green. Original bottle filling stations require just a few easy steps. Click here to watch our instructional  video.


    How easy is it to change the filter?

    Replacing your filter is as easy.

    1. Turn off the water supply; dispense water to relieve pressure. 

    2. Turn used filter left 1/4 turn to remove from filter head. 

    3. Remove cap from new filter and use to seal used filter. 

    4. Write the date of filter installation on the label. Insert new filter into existing filter head and turn fully right so the label with date is clearly visible. 

    5. Turn on water supply and run water for 10 minutes to purge air and fine carbon particles from filter. 

    6. Reset the filter monitor, if necessary. See the Use Manual for your specific drinking water unit for instructions.

    Do I have to buy the filter from Elkay?

    We recommend using a genuine Elkay filter. Our filters are designed and manufactured to work within Elkay units and provide optimum performance. To purchase filters, click here or call 800-834-4816.


    I ordered a replacement Elkay filter for my Elkay unit, and it is shorter than the original filter? Will it still work? 

    Yes. Our filters were redesigned from 12" to 9" to be more compact. They will still fit your Elkay unit and maintain current filter performance and compliance.    


    Can I add a filter to a non-filtered Elkay bottle filling station, cooler or fountain?

    Yes. Elkay offers filter retrofit kits that can be added to many existing Elkay water delivery products. The EWF3000 Filter System Kit converts a non-filtered bottle filler into a filtered unit. The EWF172 Filter System Kit converts a non-filtered cooler or fountain into a filtered unit. See table below for all retrofit options.

    Where can bottle filling stations be installed?

    Everywhere! Our comprehensive portfolio of bottle filling stations means that we are sure to have a model to fit your needs. Elkay's ezH2O® bottle filling stations are ideal for many environments both indoor and outdoor including education, commercial, health care, fitness clubs and hospitality and more. We provide solutions for wall mount, inwall and outdoor applications and offer a variety of models such as energy efficient, vandal resistant, mechanical, surface mount and architectural.


    Who can install a bottle filling station?

    We recommend installation by Elkay authorized service personnel. Call 800.952.8064 or click here to learn more about the Elkay Installation Services Program. 


    How easy is it to replace existing drinking water fixtures with an ezH2O® bottle filling station?

    It depends on the type, style and location of your current water delivery fixture. We recommend contacting a local sales representative who can provide an assessment of your site and current fixtures and suggest the best option for your specific needs. 


    How long does it take to install a bottle filling station?

    On average, it takes approximately 1-2 hours to complete a retrofit installation using existing plumbing.


    How much water pressure is required?

    ezH2O® bottle filling stations are designed to operate on 20 psi to 105 psi supply line pressure. Our bi-level non-filtered units require a minimum of 40 psi supply line pressure to ensure adequate stream height from each bubbler when activated simultaneously. Bi-level filtered models, regardless of supply line pressure, cannot provide adequate stream height from each bubbler when activated simultaneously. Please consult our specification sheet for the detailed specifications for the model you are considering.

    What is lead? Where does it come from?

    For centuries, lead has been widely used in plumbing systems that transport water. Despite changes in plumbing codes making it illegal to use lead pipes or solder, lead is still found in older pipes, solder and brass fittings in existing plumbing systems. Lead is toxic and continuous exposure can cause a variety of health problems, especially in infants and children. Please visit to learn more.

    Do your products reduce lead?

    Select WaterSentry® filtration systems reduce lead to meet the requirements necessary to achieve our NSF/ANSI 53 certification, making the water cleaner and healthier.

    Water delivery product examples include:

    • Elkay Filtered Bottle Filling Stations.
    • Elkay Filtered Water Coolers.

    Our filters are also sold separately and can be retrofitted onto any existing Elkay or non-Elkay branded water cooler, fountain or bottle filling station with Elkay’s vandal-resistant retrofit filtration kit. Kits are available with and without a filter status monitor and alert.

    Do your products contain lead?

    No. Our drinking water products have been lead free for more than two decades. They are certified to NSF/ANSI 372 as lead free by the Water Quality Association.

    How does Elkay test its filters?

    Elkay tests and certifies our filters to NSF/ANSI Standard 53."NSF/ANSI Standard 53 for Drinking Water Treatment Units is the nationally recognized standard for evaluating and certifying drinking water treatment systems for the reduction of contaminants from drinking water. Water filters are tested and certified to NSF/ANSI 53 to ensure they reduce contaminants, including lead, per the requirements of the standard" (Certified Product Listing, NSF).

    What type of maintenance and cleaning is required?

    See Care and Cleaning.

    How can I tell if the bottle filling station is being used?

    You can tell how much water is being consumed from data provided by the Green Ticker™ feature on the unit. The Green Ticker counts the number of 20 oz. single-use water bottles saved from waste by using reusable bottles and cups at the ezH2O®.

    I’m getting an error message scrolling across my bottle counter area (Green Ticker™). How do I know what it means?

    In your user manual, there is a table that explains each error code and what the cause of that particular error code is for repair purposes. You can find a copy of your user manual by searching your specific SKU on our website. Simply type the SKU into the search box in the upper right corner. When the page appears, click on the Downloads tab to access your user manual.

    Where is the data tag located on the bottle filling station?

    The serial data tag is located on the bottom of the cooler. Previously, there was a separate tag for the bottle filler and an additional one on the cooler. We have consolidated it into one tag on the underside of the cooler basin.
