ZeroWater Review

Founded in 2002 in California, ZeroWater is a filtration device that can remove 99.6% of all total dissolved solids from any drinking water. The company’s goal is to reduce common impurities such as lead, chlorine, and other contaminants from tap water.

The brand uses a patented 5-stage ion exchange filter that filters dissolved solids, improving both the taste and appearance of your water. 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.

In this ZeroWater review, I’ll go over the brand’s products, features, how it works, FAQs, and more. First, let’s look through a list of pros and cons.


  • Effective filtration: ZeroWater‘s five-stage filtration system is designed to remove virtually all dissolved solids from tap water, providing you the purest-tasting water.
  • Easy to use: ZeroWater filters are easy to install and use. Simply fill the pitcher or dispenser with tap water, wait for it to filter through the cartridge, and enjoy the filtered water.
  • Cost-effective: Using ZeroWater can be more cost-effective than buying bottled water over time, as the filters can filter up to 40 gallons of water before needing to be replaced.
  • Eco-friendly: Using ZeroWater can help reduce plastic waste by eliminating the need for bottled water, which can be better for the environment.

Overall, ZeroWater can be a good option for those looking for an effective and eco-friendly way to filter tap water, but it may not be the best choice for those who prioritize speed or affordability.

How Does ZeroWater Work?

ZeroWater Review

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:

  1. Stage 1: Coarse Filter Screen – The water passes through a coarse filter screen that removes large particles such as sediment and rust.
  2. Stage 2: Foam Distributor – The water passes through a foam distributor that spreads the water evenly across the filter.
  3. 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.
  4. Stage 4: Comprehensive Ion Exchange Resin – The water passes through a comprehensive ion exchange resin that removes dissolved solids
  5. 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.
