Elkay WaterSentry Plus water bottle replacement filter — 1 Each, 0.5‑Micron, NSF‑Certified

Elkay WaterSentry Plus is a certified, self-contained replacement filter cartridge that improves taste and reduces lead, chlorine, particulates and microplastics for ezH2O bottle filling stations and compatible Elkay dispensers.

Keep public and workplace hydration stations delivering better-tasting, cleaner water by swapping in an Elkay WaterSentry Plus cartridge. Built to Elkay’s specifications, this filter is a quick-connect, 0.5-micron rated cartridge that fits ezH2O bottle filling stations, Liv Pro dispensers and select WaterSentry systems. It’s independently tested to NSF standards and designed for straightforward maintenance so facilities can minimize downtime and maintain certification integrity.

How does the WaterSentry Plus improve water taste and odor?

The cartridge uses activated carbon media to reduce chlorine taste and odor along with other aesthetic contaminants that affect flavor. Its filtration matrix captures fine particulates down to 0.5 microns, which also helps the water look and taste cleaner.

• Activated carbon removes chlorine-related tastes and smells
• 0.5-micron particle reduction improves clarity
• Helps maintain a neutral flavor for bottles and fountains

Which contaminants does this filter reduce and what certifications back it up?

WaterSentry Plus is independently tested to recognized NSF standards covering both aesthetic and health-related contaminants. Elkay lists NSF 42 and 53 performance for chlorine, particulates and lead reduction, plus NSF/ANSI 401 testing for emerging compounds like microplastics.

• NSF 42: chlorine taste and odor reduction
• NSF 53: lead and particulate reduction for improved safety
• NSF/ANSI 401: evaluated for microplastics and select contaminants

How easy is installation and maintenance for facility staff?

Installation is designed for fast, tool-free replacement: the filter uses a quick-disconnect with a 1/4-turn coupling and an automatic inlet shut-off that stops flow when removed. Elkay recommends replacing the cartridge every 3,000 gallons or once per year to maintain consistent flow and filtration performance.

• Quick-disconnect and 1/4-turn design for rapid swaps
• Automatic shut-off valve prevents leaks during change-out
• Replace every 3,000 gallons or 12 months, whichever comes first

Which systems and models are compatible with this replacement filter?

This genuine Elkay cartridge is made specifically for ezH2O bottle fillers and several Liv and WaterSentry systems. Using the original Elkay replacement helps preserve system certification and ensures the intended flow rates and contaminant reduction.

• Fits ezH2O Bottle Filling Stations (selected LZS and LZST models)
• Compatible with Liv Pro water dispensers and Universal EWF3000 systems
• Using non‑Elkay third‑party filters may void certifications

Who is this for? Facility managers, school maintenance teams, office administrators and building owners who operate Elkay ezH2O or Liv hydration stations will benefit from the WaterSentry Plus filter. It’s intended for sites that require certified contaminant reduction, reliable flow, and a straightforward cartridge change procedure to keep bottle fillers and dispensers performing as designed.
