Would RecommendBest filter for the best tasting water. Can't live without it.
From Culligan
89 year-old:
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.
From Culligan
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
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.

Love zero water
Would RecommendI have been using this system for quite some time and I recommend it to everyone I know! Love this product!
From Culligan
Need a more environmentally sustainable design
Would Not RecommendI really dislike the hard and heavy plastic casing that will last forever in the waste stream. I wish you could come up with something more sustainable. I will soon have a filter at my sink and will stop using your product.
From Culligan
Thank you for your feedback, we do have a recycling program for our filters.
Zerowater and it's filters
Would RecommendWe moved to Florida and the water here is IMPOSSIBLE to drink. I am so grateful that we bought Zerowater while we were living in NJ. We lived in a condo that was built in 1975 and you can imagine what the pipes looked like after 50 years. That's when we bought Zerowater containers, one for the fridge and a large one for the counter to cook with.
From Culligan
Black water
Would Not RecommendAll of the filters in my pack results in black water. What is going on with this brand?!
From Culligan
We certainly apologize for issue with those filters, this is not the norm for our products. A new box of 8 filters has been ordered for you at no char...
Used to be great
Would Not RecommendI am very unhappy with my last 2 orders of these filters. I order in boxes of 2 filters each. Out of 4 filters, 2 were covered in mold on the top of the filter and 1 was making the water black when filtering and tested at an 8 before I even got to use it. That means 3 of 4 filters that I paid for are unusable. These filters are not cheap but I've always felt the expense was worth it because they did such an excellent job with contaminants. However, a 75% failure rate is not sustainable.
