What Customers Are Saying
The ZeroWater filter system receives mixed reviews. Many users praise its ability to effectively filter water and produce clean, great-tasting results. However, a significant number report issues with the filters not lasting as long as advertised, often only 1-2 weeks before the water starts tasting off or the TDS reading rises sharply. Some users also experience a recurring fishy or metallic taste, making the water undrinkable. Overall, the product can be highly effective when working properly, but there are quality control and consistency issues with the filters that undermine the product's reliability.

Filters are very slow. It takes several hours to filter the water. I’ve tried shaking the filter but it didn’t fix it.
From Culligan
Plenty of Room for Improvement
Would Not RecommendRoom for Improvement because proper seal of filter needs work.
From Culligan
Thank you for contacting ZeroWater. Apologies for the issue with the filter. Please try removing the filter, drying off the threaded area of the filte...
Allergic Reaction
Would Not RecommendEver since I started drinking the filtered water, I’ve had allergic reactions. Dry mouth, inflamed tongue, sore and inflamed throat. I’m not sure what’s in the filters so I’m frustrated that I can’t find out which ingredient is making me have allergic reactions.
From Culligan
There is coconut in our filters, this information is listed in the frequently asked questions section on our website.
Filters are suddenly less effective
Would Not RecommendI’ve been using zero water filters for the past 7 years. Since Culligan has purchased them their filters are no longer lasting more than 3-4 weeks before the tds meter starts to read above a zero. It’s not cost effective to have to replace the filter every month

Improvements made since previous purchase!
Would RecommendArrived in tact in less than a week, assembly and changing to new filter easier than it was for a while. The silicone ring around circumference of filter fits well and threads without problem. Water is filtered into pitcher in just a few minutes - no back log. Basically tasteless, which is desirable indicator of minimum ppm.

My favorite filters
Would RecommendBest filter for the best tasting water. Can't live without it.

I eat only organic whenever possible and drink no other water than Zero...this is the best we can do in this day-and-age of so much pollution and we should all take responsibility to keep our bodies as healthy as possible.

Filter Effectiveness
Would RecommendVery effective at removing errant tastes from tap water.
From Culligan
A bit disappointed
I was disappointed and surprised that the water that first came out was black. It took several rinse to get through it. I never experienced that before. Also, sometimes some air bubbles get stuck and the tank stop filling up.
From Culligan
Thank you for contacting ZeroWater. An order has been placed for a replacement filter as this is not the norm for our filters. We apologize for the in...
Better off getting cases of bottled water
Would Not RecommendLasts less than a month at a minimum. It seems like it gets clogged and then I end up changing a filter out because the water won’t get filtered out.
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...
Doesn't Allow Water to Go Down
Would Not RecommendEver since zero was bought from the original owners (brand new) filters don't allow the water to go down. It used to be only once in a while now it's 1 out of every 3 filters.
From Culligan
We certainly apologize for the continued frustrations with the filters, typically this is an easy and quick fix, simply remove the filter from the con...
Design a reusable container to encapsulate filter
great filters but would zerowater please design a product (i.e. the white plastic container that encapsulates the filter) that we can reuse and NOT just throw into the landfill after one use. Other brand water filtration tanks already do this. thank you.

Long use customer
Would RecommendWe have used zero water for many years and are very pleased with the clean taste and the confidence in knowing it is clean from chemicals.
From Culligan
Always good water!
I have used Zero Water for a few years now and the water is so clean, clear and tastes great!
From Culligan
ZeroWater brings the water into range
Would RecommendHere in New Mexico, the water is really harsh, full of minerals and all sorts of things that basically register 'way off the ZeroWater gauge for "normal." We rely on ZeroWater filters to provide us with water that doesn't just taste good but which is safer for consumption.

Would RecommendI have been using your product for years. It does a fantastic job of filtering out all chemicals in my drinking water.
