Review Summary

People have become a lot more concerned with the quality of their drinking water, thanks in part to very prominent quality control failures that spent a lot of time in the headlines. The result is that people don’t entirely trust their local water systems to deliver them safe drinking water.

Zero Water’s five-stage filtration system seeks to offer consumers some assurance, by providing a redundant filter to remove yucky things like lead and other metals that municipal systems let slip by. We got our hands on one of its 10-cup filters to check it out. We also gave it a quick side-by-side comparison test to the standard Brita filter pitcher we’ve used for years.

A Quick Look:

Pros
  • Great performance
  • Delicious water quality
  • Good ingredient for other drinks
  • Good value
  • Compact
  • Quality materials
Cons
  • Filters a bit expensive
  • Pouring can be a bit messy the first times you use it

Pouring Water

First Impressions

The Zero Water system is a bit more complicated to put together than a Brita, because rather than slipping the filter in, you screw it into place. This is intended to create a complete seal to prevent water from seeping through the cracks, unfiltered. When our Brita filters water faster than normal, we often suspect this is the case.

The pitcher also takes a lot longer to let the water flow from the filling chamber down into the pitcher. When it comes to filtering water, if it’s moving slowly, it’s because it’s seeping through something with pretty small pores. The time for concern is the minute that the water is through the filter right after you pour it.

We went to pour some filtered water into our cold brew system, and the lip on the lid wouldn’t budge, so water came out from all over it. We attributed this to it being new, so it was given a wiggle. It still stuck. The pitcher comes with a dispenser at the back bottom, so you can fill a glass with the push of a button.

TDS Test

Zero Water advertises that this system can remove every solid particle from your drinking water through the filter. It included an electronic tester so you can see this for yourself. We compared the results we got from the Zero Water filter, our Brita with a new filter, and unfiltered municipal water. The Zero Water filter gave us a score of 002, the Brita was a 397, and municipal water was more than 400.

The literature that came with it said that the tester measures total dissolved solids, including lead and chromium. We’ll take their word for it. If nothing else, now that we have a base score for what unfiltered water looks like, we can have a pretty good idea what the numbers of a filter in need of replacing will look like.

Taste Test

We recommend that you take the time to educate yourself on what’s in your municipal water and demand that your local water authority deliver clean, safe drinking water. If your water has lead in it, don’t buy a filter. Hector your local and state governments until they get rid of it. If it’s unsafe, don’t drink it under any circumstances.

The only thing that matters for these tests is how water tastes, or what it does to the tastes of things you make with it.

We drank a glass filtered through the Zero Water filter and one filtered through the Brita. We could taste a difference. The Zero Water product was cleaner. The Brita water tasted like it had just a little something extra to it that reduced the experience. We also did another test by reversing the order. We got pretty much the same results.

We also made some cold brew coffee with it. We tasted lots of coffee, and very little water additive. Not only does the Zero Water system improve the taste of water, it improves the experience of drinking things made with its water.

Cost

If you go this route, you’ll pay extra. The pitcher itself is a little more. The filters are quite a bit more expensive than the Brita. Based on the taste test results, the little extra is worth the investment. So, it’s a bit more expensive, but that extra carries pretty good value.

Conclusion

We’re fans of Zero Water’s five-step filtration system. It’s not something we’re going to rely on to keep us safe – we pay attention to the city’s water quality reports for that – but it does deliver clean, delicious water that doesn’t pass along a lot of additive flavors to things we make with it. For that, we can look past our quibbles over filter price and its clumsy pouring.
