Filters dont last as long as old zero water filter
on September 10, 2025
Posted by: Candi
Length of ownership:6 months
Ever since the new company took over Zero water, the filters do not last as long before needing to be changed. It used to last 2 months before getting to a "6". The newly designed filter shot up to over 100 reading at a month and a half! The built in meter also is faulty. It is constantly wrong and says a brand new filter is bad, while my old zero water meter says its at zero. The meter is easily damaged by water. It has brown residue all inside the battery compartment. Please bring back the old system!!!

I’m done

Length of ownership:1 year or longer
Been buying these for years and the combo of the ridiculous price and the honest fact that these don’t last nearly as long as they used to—I’m done. Not sure what happened over the years but you’ve lost my business.
No, I would not recommend this to a friend.

Thank you for contacting ZeroWater. We empathize with your situation and we have spoken with many customers with this issue. Some of our customers have used other, traditional filtration systems, such as a Culligan Whole House Filter to treat the water prior to filtering through a Zero Water filter. In many cases that will cut the TDS level down enough to make the use of ZeroWater more economical.
There is very little we can do to extend the life of our filters when the water supply is so high in TDS. Our filters are designed to remove over 99% of dissolved solids; in areas with high TDS readings filter life will be short.

Replacement Filter Issue
on July 7, 2020
Posted by: Susan K
Length of ownership:1 month
I love the way the water taste, but I am going through filters too quickly. When I first purchased the system the filter lasted about a month. I just changed the filter a week ago and now I have to change it again. I'm not sure it's worth the cost.
I would recommend this to a friend!

Tested TDS on tap water it about 108, filter worked 1 week then water is out of the filter has bad flavor. The Zerowater TDS is in the 280 area so makes the tap water worse.
No, I would not recommend this to a friend.

Tastes terrible

Water tastes musty, musky, definitely not great-tasting.
It also tastes very acidic.
Together these are unpleasant.
Returning unused filter.

High Cost and availability

Length of ownership:1 year or longer
I'm tired of paying a premium for ordering 1 or 2 filters at a time. Why can't the larger quantities be ordered?
No, I would not recommend this to a friend.
