ezH2O Bottle Filling Station in Hallway

    Elkay Water Filters

    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.

    Why NSF/ANSI Standards Matter

    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

    Easy Installation

    Our water filters are point-of-use filtration solutions, meaning they can be installed anywhere your Elkay drinking water product is installed. Replacement filters are self-contained disposable 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 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. 

    How to Install/Replace an Elkay Filter

    How It Works

    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.
