Elkay WaterSentry VII Replacement Filter, 1,500-Gallon Capacity, EWF172

Elkay WaterSentry Standard-Capacity Replacement Filter for Low to Moderate-Use Facilities

In facilities with lower or more predictable water usage, high-capacity filters may not be necessary and can increase upfront costs without added benefit. Instead, these environments require a reliable replacement filter with a manageable capacity and consistent maintenance cycle.

The Elkay WaterSentry VII EWF172 is a 1,500-gallon replacement filter designed for Elkay bottle filling stations and water coolers in low to moderate-traffic environments. Compared to high-capacity options like the 3,000-gallon filter, this model supports shorter, more controlled replacement intervals, making it a practical choice for facilities with steady but lower usage.

Built with activated carbon and ATS lead-reduction media, this filter helps reduce lead, chlorine, particulates, and odor—supporting water quality compliance while improving taste. The integrated prefilter mesh captures larger sediment to help protect the filter media and maintain performance.

A ¼-turn quick-disconnect installation with automatic shut-off valve simplifies replacement, reducing maintenance time and minimizing disruption. The visual filter monitor clearly indicates when replacement is required, allowing facilities teams to maintain a proactive maintenance schedule.
