zero water pitcher reviews

ZeroWater has made a name for themselves in recent years for their wide range of inexpensive, consumer-friendly water filtration units. A long-running rivalry with the popular BRITA brand filters continues to this day.  ZeroWater’s main claim is that they filter out more impurities than their primary competitor, offering a 5-stage filtration system (compared to the 2-stage systems found elsewhere).

In this guide, we’re going to take an extended look at several of the company’s main water pitchers, outlining the good (and if necessary, the bad) in order to help you make a more informed buying decision. After that, we’ll also answer a few questions frequently asked by our readers, so be sure to stick around for that.

ZeroWater 10 Cup Pitcher Review

zerowatetr 10 cup pitcher

  • Size: (LxWxH): 10.25 x 5.50 x 11.00
  • Capacity: 8 cups in pitcher + two in reserve
  • Filter: ZeroWater Ion Exchange filter
  • Filter Life: 25-40 gallons under typical levels

Filtration System

The ten-cup variant of the ZeroWater pitcher utilizes the company’s flagship Ion Exchange filter. They claim that this 5-stage system is able to remove virtually all (read: 99.6%) detectable dissolved solids, whereas leading competitors remove “up to 50%.” The product is supposed to be able to remove traces of aluminum, lead, zinc, nitrates, and other impurities almost completely, as well as getting rid of the “chlorine” taste commonly associated with tap water sources.

The 5 stages that your water passes through each provide a different cleansing function; let’s take a quick look at each of them:

Stage 1: Coarse filter screen: This first entry point is meant to filter out sediment and other fine deposits of particles too large for the rest of the system to handle. These will usually be visible to the eye, and you may end up needing to clean this out every now and again (in our experience, this isn’t needed very often).

Stage 2: Foam distributer: This large foam section works to more evenly distribute the water across the entire surface of the filters below. This helps to avoid concentrating the water toward the center, which helps with filter longevity and effectiveness overall.

Stage 3: Multi-layer activated carbon & oxidation reduction alloy: The carbon component here is the same one found in almost all conventional filters. It helps to remove a variety of organic impurities, as well as helping improve overall taste in the process. The additional oxidation alloy removes chlorine and other heavy metals while also preventing mold from building up inside the filter over time.

Stage 4: Dual comprehensive ion exchange: This is where the magic happens. This segment of the filter strips the water of any foreign ions, returning the molecules to a purer state than before.

Stage 5: Ultra-fine screen: As one last measure of cleanliness, this ultra-fine mesh removes just about anything solid that the other sections may have missed. This is mainly for particles too small to be seen directly, and by this point, it’s unlikely that it will have much work to do.

The filter has a stated longevity of around 25-40 gallons, provided your contamination levels fall within the national average of 055 to 200 TDS (total dissolved solids). Your individual results may vary, especially if you live in an area with 200-400 TDS or more.

Overall, in our experience trying out the product, it performed admirably; testing our water after treating it, we showed a “000” TDS reading on the treated water. This was to be expected with a pristine review unit, and we’re curious to see how well the various systems hold up over an extended period of time, but for now, we’re impressed with the finished product.

Pitcher

The high quality, BPA-free plastic pitcher itself features several design cues that are worth mentioning. For one, the company claims that it offers the only filter in its class that seals around the top, allowing you to pour water while some of it is still filtering in the top reserve. Having used BRITA filters that do not allow this in the past, we find this to be extremely convenient. It also means that you can keep the reserve filled, allowing for two extra cups worth of space to be stored at any given time.

Beyond this, the 10-cup variant features a small spout positioned at the base of the handle, allowing for a quick fill of a glass without having to physically remove the pitcher from your fridge. This may seem fairly trivial, but we were genuinely impressed with these small examples of attention to detail in the product.

  • One of the most robust filtration systems designed for home use that we’ve ever tested.
  • Removes more dissolved solids than any other leading brand.
  • Stylish designs that come in a wide variety of capacities and colors.
  • Included water testing meter is a very nice addition.
  • Filters must be replaced more often than with other leading brands
  • The 5-stage filtration process is slower than simpler 2-stage filters on the market
  • Some healthy minerals may be removed during the filtration process

ZeroWater 12 Cup Pitcher

  • Size: (LxWxH): 11.63 x 5.93 x 11.00
  • Capacity: 10 cups in pitcher + 2 in reserve
  • Filter: ZeroWater Ion Exchange filter
  • Filter Life: 25-40 gallons under typical levels

The 12-cup variant of the Ready-Pour pitcher series is nearly identical to the 10-cup version, aside from the expanded capacity it provides. You’re still getting the 5-stage filtration, as well as the one-handed pull spout for bottle filling.

ZeroWater 8 Cup Pitcher

zero water 8 cup pitcher

  • Size: (LxWxH): 10.25 x 5.50 x 11.00
  • Capacity: 8 cups in a pitcher
  • Filter: ZeroWater Ion Exchange filter
  • Filter Life: 25-40 gallons under typical levels

Unlike most of the other models on this list, the 8-cup pitcher does not feature Ready-Pour technology, meaning that you cannot pour it while the top reserve is still in the process of filtering water. For some, this may be a non-issue, but we still feel it is necessary to mention for those specifically looking for this functionality.

That said, the 8-cup variant still includes the one-handed spout for filling bottles, as well as the 5-stage filtration system itself. In addition, it comes in a number of finishes, including original blue, clear, and stainless steel.

ZeroWater 6 Cup Pitcher

  • Size: (LxWxH): 10.50 x 4.87 x 9.50
  • Capacity: 6 cups in a pitcher
  • Filter: ZeroWater Ion Exchange filter
  • Filter Life: 25-40 gallons under typical levels

Like the 8-cup pitcher, the 6-cup ZeroWater product is not a Ready-Pour variant, so you’ll need to wait for your water to filter before using the device. It also does not feature the one-handed spout for filling water bottles, as the company mentions it is designed for small spaces such as mini-fridges, as well as for those who simply prefer a lightweight pitcher.

ZeroWater 23 Cup Pitcher

  • Size: (LxWxH): 10.25 x 5.50 x 11.00
  • Capacity: 23 cups in a pitcher
  • Filter: ZeroWater Ion Exchange filter
  • Filter Life: 25-40 gallons under typical levels

The 20-cup ZeroWater pitcher changes the fundamental design of the product in order to accommodate the additional capacity it provides. Though this unit does feature Ready-Pour technology, it is designed to be stationary, with the primary dispensing method tied to the one-handed spout on the front of the device.

Aside from this change, all other features remain on this unit, including the 5-stage filtration system and dedicated water quality meter. The product comes in a clear finish, as opposed to the standard ZeroWater blue found in other capacities.

ZeroWater 30 Cup Pitcher

  • Size: (LxWxH): 15.00 x 5.50 x 10.62
  • Capacity: 30 cups in pitcher
  • Filter: ZeroWater Ion Exchange filter
  • Filter Life: 25-40 gallons under typical levels

The 30-cup ZeroWater pitcher expands on the 20-cup design without altering anything significant, except for the finish (which returns to the standard blue color). The manufacturer claims that it is the largest filtered water device on the market, except for their own 40-cup specialty glass dispenser.
