Elkay Water Filters: Engineered for Performance


Elkay water filtration solutions are engineered for performance. Choose from WaterSentry® Plus, WaterSentry VII, WaterSentry Fresh, Aqua Sentry, WaterSentry Plus Residential or WaterSentry Plus Commercial. Our water filtration systems are point of use, meaning they’re conveniently installed right where drinking water is being used for a reliable and sustainable way to reduce lead and other harmful contaminants.

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.





What is NSF/ANSI Certification, and Why Is It Important?

Nationally recognized as the gold standard for evaluating and certifying drinking water treatment systems, products with these designations have been certified to reduce certain contaminants from drinking water.


NSF/ANSI 42 addresses non-health-related contaminants that may cause aesthetic effects to drinking water, including chlorine, taste and odor, and Class 1 particulate (particles sized 0.5-1 microns, such as dust, rust or sand). NSF/ANSI 53 certifies to reduce health-related contaminants, such as lead.


Elkay filters are specifically designed to fit and have been certified for use within our drinking water products. The NSF/ANSI certifications ensure that each drip and sip of water — whether from Elkay’s ezH2O® bottle filling stations, water coolers, drinking fountains or water dispensers — is not only refreshing but also cleaner and healthier. 






Easy Installation and Replacement


Elkay filters are self-contained replaceable cartridges, limiting exposure to contaminated media. The filter status light indicates when it’s time to replace your filter (on select water delivery products). Filter replacement needs vary and are dependent upon product type and filter gallon capacity.
