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.

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.

Quality notably declining

I've used these filters for 6-8 years, they used to be so good. But for the past year or so, every time I get them, they last for shorter and shorter time. They discontinued the twist off cap for a soft plastic, which started out ok but they have also gotten worse. The latest batch that I purchased leaves glue and plastic residue all over the top. Just very frustrating, it's pushed me to make the leap to a under-sink filter instead of using these.

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

High Cost and availability

I'm tired of paying a premium for ordering 1 or 2 filters at a time. Why can't the larger quantities be ordered?

Verified Purchase:Yes
Water taste sour after a short period of time this never happened when your product first came out is this how you get customers to purchase more filter before they need too? Time for me to switch brands☹

Thank you for contacting ZeroWater. After Zero Water filters have been exhausted and have not been changed, the water produced from the filter may have a distinct smell or taste and the TDS reading may be higher than your tap water. This is a result of the water passing over the “spent” Ion Exchange Resin beads. We have gone to great lengths in reducing that taste/smell in product development however this is simply a characteristic of filtering water with a Dual-Ion Exchange system.
In order to avoid a change in the taste of the water it is important to test the water regularly and change the filter when the digital meter reads 006.
If the life of your filter has changed recently this may be due to a decrease in the quality of your tap water causing the filter to expire faster than what you are normally use to.
