ZeroWater Replacement Filters, 12-Pack

I have been a zero water customer for 3 years. The old filters used to last over a month. The new filters last 2 weeks. They’re insanely overpriced for the longevity. I don’t understand how the new filters aren’t lasting. I will be looking into other options in the future.

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 live solo, so I am the only person using this pitcher. I track my water usage and it's pretty consistent day to day. I have had filters last a little over a week to about 25 days before the water starts tasting fishy or dirty and becomes undrinkable. What's extra frustrating is that my TDS meter never reads above 000, yet the filters still go bad well before the lifespan Zerowater claims they should have. Based on my usage and tap readings, they should last longer than they do. On top of that, I have had multiple issues with filter fit in my pitcher. One filter would not attach properly on the pitcher and water spilled through, so I had to toss it. Two other filters took 3 or 4 attempts before they finally fit snug enough to not leak a lot. One filter didn't even last 9 days before the taste went bad. Between the inconsistent (and shorter than advertised) lifespan and the frequent fit issues, these filters don't feel reliable, which is unfortunate because the water tastes amazing when it actually works.

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 high dose poisonous 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 toxic, causing instant neuroinflammation, migraines and brain fog. ZeroWater is the only filter whose promise matches my biological reality. As a lighthouse is for boats, my body is beacon for hidden chemicals others cant detect but are Irreversible harm to your body , and your children body. The TDS meter doesn't lie. When it reads "000," my body confirms it: zero inflammatory response. When my filter expires in 14 days instead of 40, that's not a complaint. That's a data point. It's a warning that my municipal water must have been loaded with dissolved solids and pollutants and that the filter is doing its job protecting me. That rapid exhaustion is proof. Yes, it's expensive. I have to budget for it like a medical supply. But what is the price of a clear-headed day? What is the value of not triggering neuroinflammation, no brain fog and being able to think without pain? For me, and for anyone living with autoimmune, MCAS, or chemical injury, this isn't a luxury. It's non-negotiable life support. To the company: Don't shy away from this. You aren't just selling a water pitcher. You are selling the only reliable barrier millions of us have against a progressively toxic environment. Market to us, the canaries in the coal mine. We are your most credible witnesses. To potential buyers: If your filter clogs fast, be alarmed but not at ZeroWater. Be alarmed at what's in your pipes. This device is telling you the truth your body hasn't started screaming yet. Listen to it

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.

We have used the ZERO water filter for about 10 years.

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 last filter.

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.

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 label on top. These filters are too expensive to replace every month.

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.

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.

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!!!

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.

You claim it was all delivered - but I only received 8 in one box and the other 4 that was delivered seprate never showed up at my house! I try calling Target and no one answered the phone!

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

I love these water filters. Seriously, cleanest water ever. We’ve used another system for many, many years…swapped to this one and the difference is incredible. But the drawback is the cost, and how often they have to be changed. It’s ridiculous. We have the 23c dispenser. We use the water for drinking only (including for our 4lb dog and 2 small birds). But the filter needs to be changed every 2-3wks. The weeks is pushing it. At the price of the filters, which is a hard pill to swallow regardless how good the water is, it’s just not cost effective.

We love our water filtration system for the most part. The water taste great and cost less than many other filters and works better. However, the pitcher design itself needs work. I’ve broken two pictures already trying to get the plastic piece off so that I could change the filter. It’s very hard to get off without breaking and another thing is it’s very hard to lift the white piece out of the blue picture without breaking it. If the design could be better on the physical product it would be so much better but the filters themselves really work. Also I just wanna say that I live in birmingham,Alabama on your website it says our TDS reading is around 112. My water reads 179. Birmingham has one of the most abysmal water filtration systems in the country. They’re probably giving you that number because they don’t want anyone to know how absolutely terrible of a job they doing cleaning our water.

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