Would RecommendMy family and I have been using this these filters for years. Great water taste with the added safety from lead and other contaminants!

Awful
Would Not RecommendOne filter used to last me months...now I'm lucky if i can get through a month without having to change it because the filter makes my water taste like rotting fish even though it's still showing zero dissolved solids in the water. Buying bottled water would be cheaper at this point. For the price, this is ridiculous.

Strange citrus flavor develops after 2 weeks
I bought a pitcher plus 3 filters almost 2 months ago and I like the product but I'm on the final filter already. Around the 2-week point of each filter, a strange almost citrus taste develops even though that flavor isn't present in the source water. I'm not sure what volume of water has passed through it at that point but the flavor is strong enough that it's not really drinkable. Which is a shame because the filters seem very effective. Took our 200+ TDS water down to zero.

Bad filter
Would Recommendthis is the first time I have purchased the filters from this site and when I measured the water content it was at 28!!! Not happy with this site so far...
From Culligan
Thank you for contacting ZeroWater. The most accurate way to get reading is to test the water directly inside the pitcher. You can do this by removing...
Could be better
Would RecommendMy filters only last 2 to 3 weeks before the water is nasty again. It's really disappointing and expensive ðŸ˜

Clean water, even in Flint
Would RecommendLove how clean my water tastes. I live in Flint, MI where the warer crisis happened (still hasn't really gone away). My water is still a little discolored, but at least there's "no more lead" and with the filters, I have clean drinking water. It was nice when we got the huge discount during the crises, but since its technically over. Anyway, I dont like the new peel off lid and is there a recycling program or something for the used filters? Other than that, great product and as long as there's n...

Filters quit flowing

Zero Filters Only Last a Week!
Would Not RecommendI’ve had a Zero Water filter for years and loved it. I stopped using for a couple of years bc I moved to an apartment that had a water filter system. I recently moved and started using the Zero Water filter and the new filters only last me a week before the water starts to taste sour. I’m only one person, and it’s completely ridiculous and wasteful that these filters have such a short life. I called Zero Water and they said it depends on the TDS in my area, well I tested it and it’s nothing craz...

If you like fish, these filters are for you.
Would Not RecommendGreat until my water taste like fish. Filters don't last as long as advertised.

Don't just go by the meter on this Filter.
The taste goes bad before the meter shows contaminants.

Thank you for contacting ZeroWater. Sorry to hear of the issue with your meter. An order has been placed for a replacement. Allow 5-7 business days fo...
Great value
Great value, definitely would recommend if some had poor quality drinking water, our municipal water has a string iron and chlorine taste and smell, tested 329 ppm, even through the frudge filter (which was for taste only) it was still in the 200s....now, we have Zero water!
From Culligan
Best filter ever
Would RecommendThis is the best water filter I have ever used. There are two other brands I purchased that were so bad that I threw them out.
From Culligan
Did something change?
I have been using this product for several years. I took a break from it and when I came back it seemed as though the filters took a really long time to filter water. I have had water in the upper reservoir for 12+ hours before. I don't remember that ever being a problem before.
From Culligan
Thank you for contacting ZeroWater. From time to time the filter can develop an air lock, some little air pockets or air bubbles that get trapped down...
great tasting water
Would RecommendI never thought water could taste so good! These filters are amazing and last about 4-5 months here in NYC. I am so glad that I made the switch from Britta to Zero! The only thing that I had trouble with the replacement filter is that it doesn't seal as good as the filter that originally came with the pitcher. I just needed to tighten it a bit more so that it would seal off better. Now all is good.
From Culligan
Product quality
Would RecommendGreat product . Water quality greatly improved by using water filter. Improve the taste as well.
From Culligan
great help, after purchase
Would RecommendWe purchased the large, glass counter top unit, 40 cup... last summer. Then it was time to change the filter. A couple of days ago, we purchased the filter package (of 2) since we save a bit of $ that way. Every attempt to get the one new filter on wasn't working: it always went on slightly crooked. This meant tap water streamed out of the TOP of the filter, before ever going thru all the stages. Ugh! We call & spoke with Tyler. Very nice person. When I to...

Works great for family and pets.
Would RecommendWe have been using Zerowater filters exclusively for many years. For our current household of four adults and five pets we use tap water filtered through a floor-standing water cooler/heater, plus counter-top dispenser, and pitcher. Never had a problem with the filters or a complaint about the taste. Never had an illness or problem from the filtered water. Have used the filters in two different states, NY and FL, where there were sometimes public warnings about tap water. We expect to continue u...
