We offer NSF-certified replacement filters designed specifically for bottle filling stations, including options like the Elkay 51300C WaterSentry Plus Filter. These filters effectively remove contaminants such as lead, PFAS (PFOA/PFOS), microplastics, and other impurities commonly found in water sources for schools, offices, and facilities.

Our replacement filters are compatible with leading brands including Elkay (e.g., Elkay bottle fillers), Halsey Taylor, Oasis, and Murdock. For example, the Elkay 51300C is tailored for Elkay models to ensure a proper fit and optimal performance.

Filter replacement frequency depends on usage and water quality, but we recommend checking the manufacturer's guidelines for your specific model—typically every 6-12 months for high-traffic areas like schools. Regular replacement ensures continued contaminant removal and maintains peak water flow.

All replacement filters qualify for free shipping across the continental U.S. with no minimum order. First-time buyers can apply code WELCOME10 for 10% off at checkout, and if you're buying more than 2, email support@bottlefillingstations.com for bulk discount pricing.
