Great for bulk purchase of OEM filters
Quick sipping and brand new. I appreciate the bulk purchase option, as it can be a burden to buy too frequently. Will definitely buy again whenever needed.

Filters don’t last long
I have used zero water pitcher for years but ever since Culligan bought it the filters don’t last as long, they have gotten worse. I ordered filters from Zero. I am one person using the picture and it’s at .006 after. 2 1/2 weeks! Filters Use to last 2+ months.

Water as it was meant to be - pure and drinkable
We have used the 12 cup Legacy series for several years. We avoid unfiltered tap water and bottled water at all costs. Our tap water generally registers between 250 and 400 particles, so our filters last between 4 weeks and 6 weeks. Many people complain that sometimes the filters don't drain properly. That is more than likely because they have a bubble of air trappe...

Zero total dissolved solids by measure
I have been using Culligan zero water for about 18 months. The water here locally has 120 to 135 total dissolve solids and zero consistently after filtration. Today it was five and gratefully new filters came. Thank you!

Absolute Scam
The filters last about 7-10 days and then give off a metallic taste, almost like they are designed to fail. In addition, you have to jump through hoops to recycle them.

I'm done too
These filters only last a couple weeks before water starts to taste fishy. Also lots of carbon particles floating in reservoirs. I am the only one in home. For the price of these filters they should last alot 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.

Adding to what everyone has said
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. There's only two individuals using the pitcher and we are not home for the majority of the day. We used the water primarily for morni...

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.

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.
