Purchased new pitcher and filters on Oct. 2. Water tasted fine and had no issues. It's Oct. 17 and the water tasted sour. I wished I read the reviews, but it was a sign that I needed to change the filter and the water tester did read 006.

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,...

Defective Filters
I used to love my “Zero Water” pitcher/ filter system. However, I’ve been having problems for over a year with the filter only lasting only a month! It goes from (0 to 5-6 TDS) then continues to rise. Additionally, the water will often times not drain through the filter. I’ve contacted the company at least 3 times before & after Zero became Culligan. I was sent new filt...

Moisture
Like to know why filters I've been buying have moisture inside.
They should not have any type of water inside. This deteriorate the filters while in atirage.

Thank you for taking the time to post a review. We are sorry to hear of your dissatisfaction. Filters are rinsed with purified water before they are packaged. This has no negative impact on filter life. If you have additional questions, please call out Customer Service Team at 800-503-2939, we will be happy to assist you.

Wish filter lasted longer
I had first gen Culligan filter and believed enough in the idea to try their new “longer lasting” 2nd gen filter, bought a new pitcher, etc.
New “longer lasting” filter only lasts 1-2 weeks for our family of four. It’s a lot of hassle and expense to change the filters this often.

Filters dont last as long as old zero water filter
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...

Very short life
It filtered well for about one month, perhaps 20 uses. I was really disappointed. It says it’s 35% longer life but longer than what? Does not seem cost effective if I need to purchase every month.

Not as expected
The new filter provides a reading of 007 instead 000 as expected. Anything above 006 ppm means time for replacement. Not what I expected

Now new filters. That was and isn’t needed.
Zero has always been good to our family, creating affordable filtration that works supremely well, producing great tasting water at affordable prices. But since the Culligan takeover, they’re not Zero anymore. Case in point we have the large glass countertop model that has worked perfectly for years. Now Culligan has changed the filters. Now you can still buy the old...

Cleanest Water on the Market!
I have been using ZeroWater technology for over a decade now and have peace of mind knowing that I am drinking the cleanest and healthiest water I can get on the market. That is until the new Culligan/Zerowater systems came out. I recently upgraded to the new 33 cup Culligan filter system, and I am again impressed with the new filter specifications and operation of th...

Major Filter Design Flaw
Of the 10 filters I've used with the 32 cup dispenser, only 2 have worked properly. Most will work for a week or two, and then stop filtering - or will filter only when the bottom of the filter is above the water line in the dispenser. So frustrating. I just purchased 4 more filters, and the first one won't filter at all. So frustrating. I want a refund so I can bu...

Don’t last long. Water smells even if tester at 0
We’ve been using Zero Water for a few years. Recently, I change the filter and it’s all 0. Then, 2 or 4 weeks later the water from it has an unacceptable odor per my wife and I have to change it again. Our tap water is around 160 - 180

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 mo...

Air bubbles
These 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.

Response from Staples :
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 inside the filter. Typically this is an easy and quick fix, simply remove the filter from the container and unscrew it from the tray. Then hold the filter sideways/horizontal and grip the filter very tightly and shake the filter with some good force side to side and back and forth 8 to 10 times. This will loosen the filter media and break the air lock.

The new filters leak in my pitcher.
The 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.
