Product Overview
The official replacement filter for ZeroWater systems was designed specifically with use in compatible ZeroWater pitchers and ZeroWater systems. This replacement filter works using a combination of a 5 stage filtration process including an ion exchange process to remove dissolved solids from your tap water, which can help make your tap water taste better.
The parts that make up the filter housing are all constructed out of BPA free materials, and they are food grade safe. With its ability to significantly lower total dissolved solids when you're using it in a compatible ZeroWater system, many people rely on this type of replacement filter to provide them with clean drinking water for their every day needs (coffee/tea/etc.).
Customers Say
Many consumers have stated that this water filter has a noticeable effect on improving the quality of taste in their tap water, reducing any mineral or metallic aftertaste. Consumers have reported that the filtered water tasted better and that it worked extremely well when making coffee and tea.
Consumers are also pleased by the ability to measure the performance of the filter using a TDS Meter. A number of consumers have reported significant drops in dissolved solids from higher readings down to nearly zero when the filter was new.
The most common complaints regarding this product are related to the life expectancy of the filter and its reliability. A few consumers have reported that they were unable to achieve the same longevity in the later replacement filters as had been achieved in the early replacement filters. Additionally some consumers have reported a drop off in effectiveness in addition to receiving poor quality and broken filters at times.

Bottom Line
The Zero Water Official Replacement Filter is a good choice to remove much of the dissolved solids and make the taste of your water better if you have a Zero Water pitcher or dispenser at home. The two best things about this filter are its 5 stage filtration process and ability to measure how well it reduces TDS in your water. The worst thing about this filter is it can be expensive to replace and may not last as long based on what type of contaminants are in the water where you live.
