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.

Water as it was meant to be - pure and drinkable

Would Recommend

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 trapped inside the filter. In that case, just remove the filter and turn it sideways and shake it as hard as you can for about 7 - 8 ...

Filters don’t last long

Would Not Recommend

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.

Best option

I have used this product for over two years and have found it to be very good and saves me money and trips to the store for heavy plastic bottles

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!

I have been truly happy with the zero water filter

I have been using the zero water filter for over a year and the water taste so much better than bottled waters

If Your Filter Dies Fast,Your Water is the proble

This Isn't an Appliance; It's My Medical Equipment The Truth Other Reviews Miss: I see the complaints:"Filters only last two weeks!" "Too expensive!" I understand the frustration. But I need you to understand what that short lifespan actually means. My body is a chemical injury survivor. Childhood chemotherapy rewired my nervous system to detect toxins at levels "safe" for others. For me, tap water—and most bottled water—isn't just bad tasting; it's acutely poisonous, causing instant nueroinfl...

I'm done too

Would Not Recommend

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!

I’m done

Would Not Recommend

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

Would Not Recommend

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 morning coffee/tea and pets water bowl. This is not a sustainable product. I will be searching for a better product after I use up my...

Quality notably declining

Would Not Recommend

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.

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 filters (at my expense) but the new ones are doing the same thing. I believe they are what is called Legacy filters with the black l...

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.

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 at zero. The meter is easily damaged by water. It has brown residue all inside the battery compartment. Please bring back the...

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.

True zero water tested!

Very reliable compare to Brita this is true! I will recommend to my sisters and friends.

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

From Culligan

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 Zero filters but if you want to convert to the new filters, you have to buy an entire new container. All Culligan would have t...
