They carry a line of water filter pitchers, dispensers, and accessories. The filter systems are certified by the NSF International to reduce lead, chromium and PFOA/PFOS.

How Does ZeroWater Work?
As mentioned in this ZeroWater review, the brand uses a five-stage filter to remove dissolved solids from tap water. Here’s how it works:
- Stage 1: Coarse Filter Screen – The water passes through a coarse filter screen that removes large particles such as sediment and rust.
- Stage 2: Foam Distributor – The water passes through a foam distributor that spreads the water evenly across the filter.
- Stage 3: Activated Carbon and Oxidation Reduction Alloy – The water passes through a layer of activated carbon and an oxidation reduction alloy, which removes chlorine, metals, and other impurities that can affect the taste and odor of the water.
- Stage 4: Comprehensive Ion Exchange Resin – The water passes through a comprehensive ion exchange resin that removes dissolved solids
- Stage 5: Ultra-Fine Screen and Non-Woven Membrane Layers – The water passes through a final stage of ultra-fine screen and non-woven membrane layers that remove any remaining particles, including microscopic particles that can affect the appearance and taste of the water.
As a result, virtually all total dissolved solids are removed from the water leaving only the purest-tasting water. Zero Water is designed to remove 99.6% of dissolved solids from tap water, which is much more than most other water filtration systems on the market.
To use ZeroWater, simply fill the reservoir with tap water and let it filter through the five-stage filter. The filtered water will collect in the bottom of the pitcher or dispenser and is ready to drink.

“We are very happy with the new design of this dispenser. The indents on the canister designed for carrying make it much safer for moving a filled dispenser. Also, the new dispensing valve is a huge improvement over the old push button valve which was hard to operate, especially for elderly folks and people with arthritis. Thank you so much for the much needed improvements.”
Another said, “Zero water filters are reliable and effective. For treating municipal water with low mineral content (I live in western Oregon), the filters last a very long time (35 ppm municipal water, and a filter lasts several weeks. At $15 a filter for all our drinking and cooking water, that is a good value.”
On Walmart’s website, a ZeroWater pitcher received a score of 4.5/5 stars out of 502 reviews. One consumer stated, “Saw TV advertisement about all of the filtration stages in ZeroWater that results in a “0” result.
