New filter just put in has a reading of .11 and tastes bad.

stars-rating-full stars-rating-full stars-rating-full stars-rating-full stars-rating-full

A new filter did not read below 0.06. They immediately said no problem and are sending a new one.

No hassle. Great company.

User's recommendation: This is a great company that quickly answers any questions and resolves issues immediately. You actually get to speak to a live agent!

Poor performance and even worse customer service

stars-rating-full stars-rating-full stars-rating-full stars-rating-full stars-rating-full
AI Highlights
  • - Disappointed with ZeroWater and its replacement filters.
  • - Refund requested; not recommended due to quality concerns.
Updated by user Jun 24, 2026

Customer service so far has been beyond horrible. 6/24.

Original review Jun 24, 2026
I am extremely disappointed with ZeroWater and its replacement filters. What was marketed as a premium water filtration system has turned into a complete waste of money.
The replacement filters barely last anywhere close to what customers would reasonably expect.

In many cases, the filters begin failing after a very short period, resulting in poor-tasting water and TDS readings that quickly rise again. Given the high cost of replacement filters, the value proposition is simply unacceptable.
What is even more frustrating is that customers are forced to continually purchase expensive filters that do not perform consistently or last nearly long enough to justify their price. A filtration system is supposed to provide reliability and peace of mindnot constant frustration and recurring expenses.
I purchased this product expecting quality and durability. Instead, I received a system that requires frequent filter replacements and delivers inconsistent performance.

This experience has left me feeling misled and disappointed.
I am formally requesting a full refund for both the filtration system and the replacement filters. A product that fails to meet reasonable expectations for performance and longevity should not leave customers absorbing the financial loss.
I cannot recommend ZeroWater to anyone based on my experience and would strongly encourage the company to address these ongoing quality and durability concerns.
Loss:
$2500

Preferred solution: Full refund

User's recommendation: DO NOT BUY

Terrible product lasted less than 2 weeks with one person using it in the WDC burbs

stars-rating-full stars-rating-full stars-rating-full stars-rating-full stars-rating-full
AI Highlights
  • - Product lasted less than two weeks and stopped filtering.
  • - Water is undrinkable without trace minerals.

Completely ridicules solution The product lasted less than two weeks. The water is undrinkable without trace minerals and only got worse as I used it.

My water is between 200 and 220 from the Potomac River and the water filtration plant on river road in Potomac MD I am the only user and its been less than two weeks

my meter showed 001 on Friday its now Tuesday and it stopped filtering. I took it out and gently tapped the sides and turned it upside down and it is now filtering with a new reading of 003.

User's recommendation: Don't buy it

Filters are no good since Culligan took over

stars-rating-full stars-rating-full stars-rating-full stars-rating-full stars-rating-full

The last dozen+ filters I've bought have been bad. I just installed a brand new filter, right out of the box - purchased recently - and the water tastes like plastic, same as when the filter is old.

This never happened before Culligan took over. I can only assume they are responsible for the poor quality.

I opened a water filter and it was full of ants. I had to throw it away. I want it replaced.

  • - A replacement filter is being sent.
  • - The service rep was friendly and said the replacement would arrive in five days, and the company stands behind its products.

Pros:
  • Water tastes freat
Cons:
  • Filters are expensive and do not always last too long even with the same uae

User's recommendation: Call them is you have any issues. They will help you.

New filter does not work.

stars-rating-full stars-rating-full stars-rating-full stars-rating-full stars-rating-full
AI Highlights
  • - New filters do not work.
  • - Eight replacements sent; still not working.
  • - Customer service offered four solutions; none helped.

New filters do not work. Sent 8 replacements and they don't work.

I called customer service and received 4 different ways to solve problems, which keeps me busy but not gives any solution. I have used Zero Water for more than a year; this is a new problem. Surely they have figured it out by now. When sending replacements, they don't request the old filter.

How can they learn what is happening? Are they sending lots that are defective?

Loss:
$60
Pros:
  • When working filters well
Cons:
  • Very difficult to get working

User's recommendation: I’m losing faith in product, to much work.

New filters not working

stars-rating-full stars-rating-full stars-rating-full stars-rating-full stars-rating-full
AI Highlights
  • - Spent days trying fixes (shaking, pounding, partial fill) to release air bubbles; filtration remains nominal after 24 hours and the issue recurs.

Spent days repeatedly shaking the filter, pounding on the side, and partially filling the reservoir, allowing air bubbles to come out. Give me a foolproof method to get this filter to work.

It only has nominal filtration in 24 hours. This is a recurring problem in the past 6 months.

Pros:
  • High degree of filtration
  • When working
Cons:
  • Very difficult to get working

Preferred solution: Foolproof remedy, what has changed with product. I have used zero water for 2 years, there is a difference

User's recommendation: Requires Hugh amount of patience, an even after 4 days of effort, may never work

Functioning of filter system

The representative informed me that there were more than likely air bubbles trapped in the filter after tapping it aggressively on all sides I am now attempting to see if that resolves the issue

Tainted filters

AI Highlights
  • - Pitcher is faulty; filters weren’t the issue, they aren’t sold anymore.
  • - Zero Water offered a replacement, but only smallest pitcher was available.

Turns out its not the filters(already threw away) but the pitcher is faulty and I see they dont sell them anymore. Also confused as to the difference between culligan and zero water.

I thought it was the same company? So person at zero said they would replace the pitcher but they only had the smallest one available which really does me no good but I wasnt given a choice:(

Question about about newest product

AI Highlights
  • - Customer cannot reach live agent and keeps getting Josh.
  • - Customer ordered from Amazon, got a ZeroWater unit, and seeks confirmation on newest model.
Updated by user Apr 19, 2025

I’m nice I was s as now to talk to them, it was good.

Original review Apr 12, 2025

I'm thinking of choosing another company as you cannot talk to a live agent and get Josh over and over. My son has a ZeroWater system and told me he got an email that a new one is out.

I ordered and received one from Amazon. I want to know if Amazon has the newest model. I can't tell from the Amazon website, but Josh tells me they do.

Please tell me how to proceed. I prefer Amazon because there is no shipping cost.

User's recommendation: One because of inability to speak to human in customer service

  • - Filters are expensive and time consuming; tester unreliable.
  • - Changed filter after one month.
  • - Water tasted like lemons.

My zero water filter takes hours to filter a pitcher of water. I find the filters to be very expensive and time consuming, I might just return it and get something more affordable.

I had to change the filter after only one month, the water tasted like lemons. I tested the water the day before and it was 0, the next day it was 254.

The tester is not reliable. Bottom line is this thing is a time and money consuming pain in the a

  • Water tastes good and device does show zero pds

ZeroWater introduces water filtering system that removes almost anything from the water, lead, perchlorates, antibiotics, hormones and other contaminants.
