5-Stage Ion Exchange Filtration

ZeroWater’s patented 5-Stage Ion Exchange Filtration system removes 99% of all Fluoride and other inorganics, such as nitrates. Your water will first pass through a coarse filter screen to remove any suspended solids such as rust and dirt that make your water appear cloudy, and then a foam distributor will remove any additional suspended solids. Next, a multi-layer activated carbon and oxidation reduction alloy will remove organic contaminants such as Mercury, Chlorine, Chloramine, pesticides and herbicides while stopping bacteria from growing. The Dual Comprehensive Ion Exchange Resin will then remove inorganic compounds such as metals, non-metals and even radiological contaminants. Finally, an ultra-fine screen and non-woven membrane layers will remove any remaining solids. IAPMO certification proves the filter reduces PFOA/PFOS (“forever chemicals”), Lead, Chromium and Mercury, rest assured your water is of the highest quality.

Stress-free, quality water filtration

It is not uncommon for UK tap water to contain TDS (Total Dissolved Solids) between 100-500 PPM. You can worry less about water quality when using authentic ZeroWater replacement filters. After passing through ZeroWater’s patented 5-Stage Ion Exchange Filtration system your water will have “000” PPM (Parts Per Million) leaving you confident in the quality of your drinking water. Please note that it is normal for this measurement to increase as the filtration system ages while still filtering your water to an immaculate degree. Use your free laboratory-grade water metre included with the purchase of any ZeroWater filtration device to check your TDS levels and once the metre reads “006” or above, replace your filter to ensure you are maintaining high-quality water filtration.
