From Culligan
Filter quality dramatically dropped recently
I've noticed these filters don't last as long as they used to before the water starts tasting off and the TDS numbers skyrocket. This started a couple months ago and I find it hard to believe the tap water quality has gotten so bad the filters last 1-2 weeks when they used to last 4-6 weeks. The amount of time the filters last has decreased dramatically in the past 6 months from 6 weeks to 4-6 to 3-4, and now 1.5-2 weeks. Less than 2 weeks is ridiculous.

Beware of Microplastics from Zero Filters
The plastic packaging at the top of the filters flakes off into the water....

Air bubbles
Would RecommendThese work very well most of the time. Lately I’ve been having difficulty with all of the water filtering down. It seems like air gets trapped in the filter. I have to tilt the pitcher until I get the air bubbles out before all the water can filter.
From Culligan
The new filters leak in my pitcher.
Would Not RecommendThe new filters are useless. They do not seal in my pitcher - only in my 5 gal unit. My old filter seals just fine in my pitcher, so it's not my unit. I knew when Culligan took this over the quality would drop.

Not bad
Would RecommendLike the ZeroWater system very much, but from time to time the filters just won’t filter the water.
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...
These only last a week?
Would Not RecommendIve been using these filters for a while but the last box of 6 I ordered are horrible. Each filter has only lasted a week before the water starts tasting terrible.
From Culligan
We apologize for the short life on your last box of filters, we have placed an order to have them replaced for you.
You're STILL the BEST!
I have been using ZeroWater for a couple of years now and I must say the water definitely tastes better than the "other major brand". Thank you ZeroWater!

Awesome 5 stage water filter
Would RecommendAwesome 5 stage water filter! I have used Zero water filters for years- I use it both at home and at our cabin. I have tested our water at home both before (meter read 371) and after ( meter read 000) filtering. I won't use any other water filtering system
From Culligan
Slow filtering
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
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...
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.
From Culligan
My favorite filters
Would RecommendBest filter for the best tasting water. Can't live without it.
