1/12/2026 UPDATE: After I posted this review, I went to the Culligan/zero water customer service site looking for an email address. Which I found and I in essence posted my review to customer service. They actually responded back to me, apologized and sent me two new filters which arrived today. Right now I feel as though customer service was given, and I’m happy with the outcome. I purchased zero water because I trusted Culligan. I liked that it advertised particular removal and taste improvement. The first filter I had which was included in a box that I bought the countertop container worked fine. I was very happy although I did think it lasted less than a month and I’m one person. I purchased a pack of two replacement filters paid a little bit more than $40 total and neither one of them perform like the first. I followed all troubleshooting suggestions from Culligan and zero Water sites. I submerged it for 15 minutes totally to try to get air out of both in the event that there was air because that was suggested. I rinsed and re-soaked refilled, and still had the same taste of carbon or metallic. The filter gauge attached to the countertop dispenser said 000 for both filters after both problem-solving. It’s still tasted awful. Never thought to be more prudent in looking for a guarantee or warranty, but I was told there’s a 30 day guarantee for the filters, but you have to have your receipt. I should’ve just stuck with Brita.

Listen to all of the other reviews. First filter lasted 3 weeks, it is now down to one filter a week. I live alone and drink 24 oz per day. At 27ppm the water tastes terrible. I will use up the rest of the filters and toss the large capacity tank I purchased. Going back to Lifestraw

The replacement filters used to come with a blue cap on top. Now it comes with a plastic seal. This is so hard to get off and leaves plastic particles in the top of the filters. It has taken me about 10 minutes to remove most of it. I can’t get it totally off. Please go back to blue caps. Much easier and cleaner to remove.

Although the product is good and convenient I am finding the filters are not as good as they used to be. They stop filtering after a week, despite the meter reading being fine. They said to tap the filter to release the air, and tighten the connections, which I’ve done numerous times, but the water is still not filtering through. I’m considering trying a different system as the filters are not cheap.

I live alone and drink approx 1.5-1.8 litres per day after 2 weeks water has a distinctly unpleasant taste. The TDS meter reading is 001, so should be okay to use. This now seems to be a constant problem with these filters. I've been using zero for a few years. I'm sure they are now made to last a lot less than before. I'll buy a table top reverse osmosis device & ditch ZeroWater

Well I should have listened to the recent reviews. The filter lasted 2 weeks. It’s very expensive, it went up on price. I’ve been using zero water for a few years, I have never come across this problem before. Before it would last about 2months. They are trying to make more money, but actually they’re going to lose customers. I am currently looking for new options. I feel cheated.

I would give a BIG Zero stars if i could. This company is horrible. I bought the Extreme Life filter that attaches to your sink faucet. It cost me 80 dollars. Before my filter needs replacement I thought I will order some more filters. The product is already discontinued without notice and now I am stuck with this product. What a waste of money. I called customer service and they don't care at all and wouldnt even offer to replace it with one of their cheap pitchers or other product. This is a horrible company. I will never purchase anything from this company again. What a very bad experience.. Zero stars.. and certainly Zero Customer Appreciation.

Paul, from customer service, turned a somewhat disappointing experience into a phenomenal experience. Absolutely incredible company, I would rate this 10 out of five stories if I could.
