The Elkay ERF750 WaterSentry residential filter delivers safe, reliable water filtration for your home. Engineered for use with residential Liv dispensers, faucets, and bottle-filling systems, this genuine Elkay cartridge is certified to NSF/ANSI standards 42, 53, and 401, reducing lead, microplastics, chlorine taste & odor, and Class I particulates. With a rated capacity of 750 gallons (or 12 months), the ERF750 balances performance and cost. The ¼-turn quick-disconnect design and automatic shut-off make changing your filter easy and mess-free. Elkay’s activated carbon filter media not only filters contaminants but also improves odor and taste. Counterfeit and third-party filters may look similar but are not tested to these standards and may compromise performance. Genuine Elkay filters help ensure safe operation, maintain certification, and protect the long-term integrity of your equipment.
