ezH2O Bottle Filling Station in Hallway

    Healthier Hydration is Within Reach

    Healthier Hydration Made Easy

    We are in the business of delivering drinking water wherever you need it. Enhance this experience by providing cleaner and healthier drinking water when you choose an Elkay drinking water solution with filtration. Engineered for performance, our water filters are tested and certified to NSF/ANSI 42 and 53 for the reduction of harmful contaminants. This is important because contaminants, such as lead, cysts and Class I particulates, can’t be detected through sight, smell or taste. Elkay water filters give you confidence that you know what’s NOT in your drinking water.

    Made with activated carbon to improve taste and odor, Elkay water filters are NSF/ANSI 42 and 53 certified — allowing you to deliver cleaner, healthier drinking water wherever you need it.

    How It Works

    Elkay water filters help reduce contaminants for cleaner, healthier water. How do we achieve this? Radial flow-thru design and ATS-treated activated carbon effectively treat incoming water, while the spun polypropylene prefilter mesh prevents large, coarse sediment and particles from entering and clogging filter media.

    Our Retrofit Filtration System Kits enable you to convert your unfiltered drinking water product into a filtered solution. This easy conversion maximizes your existing water delivery solution.

    How Elkay Filters Work



    NSF Logo

    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 varies; check individual product page for more information.



    Easy Installation and Replacement

    Elkay water filters are point-of-use filtration solutions, meaning they can be installed anywhere your Elkay drinking water product is installed. Radial flow-thru design and ATS-treated activated carbon effectively treat incoming water, while the spun polypropylene prefilter mesh prevents large, coarse sediment and particles from entering and clogging filter media. Retrofit Filtration System Kits allow conversion of an unfiltered drinking water product into a filtered solution.

    Replacement filters are self-contained replaceable cartridges, limiting exposure to contaminated media. Quick-disconnect, quarter-turn installation makes filter replacements easy, while an automatic inlet shut-off valve closes when the filter is removed to minimize spills.

    Water delivery products with a filter status indicator light will let you know when it’s time to replace your water filter. Filter replacement needs vary and are dependent upon product type, filter gallon capacity and usage. Refer to our Water Filtration Selection Guide for details.

    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. It is rated for 3,000 gallons.

    What does the filter remove from the water?

    Elkay’s WaterSentry® Plus filter reduces aesthetic chlorine, taste and order, Class 1 particulate and lead. The filter has a rated capacity of 3,000 gallons.

    How long does a filter last?

    Our WaterSentry® Plus filters are rated for 3,000 gallons which is about 24,000 16-oz. bottles. Actual filter life depends on your water conditions. 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: The filter is doing its job, providing you with a cleaner, fresher drink.
    Yellow: The water is still being filtered but will need to be replaced shortly.
    Red: The filter has reached 100% of its 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 back to green. Original bottle filling stations require just a few easy steps. Click here to watch our instruction video.


    How easy is it to change the filter?

    Replacing your filter is as easy as 1, 2, 3!

    1. Turn off the water supply; then dispense water to relieve pressure (through either the bubbler or the bottle filler).
    2. Turn the used filter clockwise, a 1/4 turn to remove from the filter head and dispose. Remove red cap from new filter.
    3. Insert the new filter into the existing filter head and turn fully, counterclockwise. Make sure you can read the blue label on the front of the filter once installed.

    Enhanced models feature our FillSafe™ filter recognition that automatically identifies when a new filter is present and updates the LED light back to green. Click here to view the video tutorial.

    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 epa.gov/lead to learn more.

    Do your products reduce lead?

    Our WaterSentry® Plus and WaterSentry VII 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.
