Please note: This product does not include the water cooler base. It is designed to be placed on a compatible base, which must be purchased separately.
Already have a standard water cooler at home or in the office? Upgrade it instantly with the ZeroWater 18.9 liter filtration system and enjoy the benefits of truly purified water without heavy bottle deliveries or refills. This reusable system fits most top-loading water coolers and uses the same powerful 5-stage filter technology found in all ZeroWater products.
While standard cooler jugs simply hold tap or bottled water, this system actively removes up to 99.6 percent of dissolved solids, including heavy metals like lead, chemicals like PFAS and glyphosate, and other invisible contaminants. It is the only cooler-compatible system certified by NSF to reduce lead and chromium.
With a generous 18.9 liter capacity, it is ideal for families, offices, or shared spaces where clean water should always be within reach. It reduces plastic waste, eliminates the hassle of replacing heavy jugs, and provides peace of mind with every glass.

Perfect For:
Advanced 5-Stage Filtration for Superior Water Quality
Unlike most water filters, ZeroWater’s 5-stage filtration system removes 99.6% of all dissolved solids, including harmful substances like lead, PFAS, chromium, and glyphosate. It’s the only pour-through filter that meets the strict certification standards of the NSF for lead and chromium reduction.
Good to Know
ZeroWater filters typically last longer than standard filters, but lifespan depends on your tap water quality. The included TDS meter helps you monitor when it’s time for a filter change. Once your water measures 006 ppm or higher, it’s time to replace the filter for optimal results.
Be careful!
Do not use with water that is microbiologically unsafe or of unknown quality without adequate decontamination. Unless otherwise stated, municipal water is drinkable.
Did you know?
ZeroWater also filters all good minerals from your water, so we recommend adding 2 drops of multi-trace to your water daily for the optimal amount of minerals and trace elements.
