ZeroWater

Our southern Arizona water is undrinkable without filtration, and these do nicely, When they offer specials and you buy in quantity, the cost comes down to about $14.00 per filter, and one can last 30-45 days, depending on usage. Unfortunately, the company doesn't seem to offer specials any longer. (I thought they'd gone out of business.) But now that I'm down to my last filter, I think I'll look elsewhere for a water filter solution. Last year, they had a security breach and didn't really handle it well, in my opinion. (I was notified BY MAIL even though I order online. The notice that my card could be compromised arrived on a Saturday. Nice.)

I bought a zero water pitcher and after using it twice the water tasted like vinegar and kept getting worse. I went to buy new filters and they're double the price of Brita and Pur. I called the company to complain about the filter and after the call I kept getting a lot of"spam" calls and I'm still getting them, I think they gave out my number

The zerowater does what it is suppose to do so long as it has a clean filter.
My prolem is with the pitcher. The pitcher is poorly designed. At the very top of the handle it cracked so you cannot use the handle to pour out the water.
I called and emailed the company... no response.

I have been using the small pitcher and the bigger 40 cup holder for over a week now and the frequentency in which the units cloggs down and needs to be squezzed to get unplugged is just ridiculous. I don't recommend this product. It's filter life expectancy is overated. Cost vs. time of use, not really worth my books.

I bought stuff directly from its company (not Amazon). Slow and rude email responses, and what a diminishingly rude tone of speech over the call. It was super unprofessional. I'd probably get better service from McDonald's.
Avoid this company and install an RO filter. Or buy stuff and make sure you won't interact with them. So sad to see how this type of business can run like this. Maybe this business isn't serving great products after all. You can tell what's the inside look like from what the outside looks like (aka CS). It's all rotten, like fungi. And I got no business dealing with a fungi-like company, especially when it's supposed to serve clean water.

We moved into an apartment complex that had bad tasting water. I saw the commercial on TV, so I thought "here is my answer!" So in August 2019, we purchased the 4.6 Cup Zero Water Pitcher that came with a water quality meter and one filter.

Out of the box, the meter didn't work; it registered 334 on the water. The water tasted better, so I didn't worry about the meter. Over the next 11 months, we purchased 10 additional filters. Sometimes the water was better, and sometimes the water tasted so terrible that I discarded the filter and used a new one.

Contemporaneously, we had a problem with instant coffee and hot tea. When we added milk to our hot drink, it appeared like the milk curdled, and the drink would get thick. It was like we had added a thickener. We tried all sorts of things to figure out what the problem was. Never once did we even consider it might be our filtered water.

In October 2020, I put in a new Zero filter, but it had a metallic smell right out of the box. So that morning I used regular tap water. The milk didn't curdle. The light went on in my brain. It was the chemicals in the Zero filter. I tried making one more cup of instant coffee with the stinky filtered water; the milk curdled. I made a second cup with tap water; the milk did not curdle.

So my evaluation is P U.

I was given a new Zero Water dispenser. There is a button to press to dispense the water. The button has to be pressed for the duration of water dispensing, and it is hard to hold. The filters are ridiculously expensive and don't even last that long. The water doesn't taste as good as it should. After about 3 months, the water wouldn't drain out of the reservoir into the dispenser at all. I'd had enough, threw it out, and replaced it with old faithful.
