ZeroWater Replacement Filters, 12-Pack: BPA-Free, 5-Stage, Pitcher Compatible, Filters Lead & Chlorine, 15 Gallon Life

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

I’ve now gone through three separate ZeroWater filters, and each time, the pattern has been the same: fresh, clean-tasting water at first, followed by a noticeably fishy or metallic taste after just a couple of weeks of normal use. This isn't a subtle issue – the off-putting flavor makes the water undrinkable. I double-checked my tap water, storage conditions, and filter usage, and the result was consistent: something in the filter itself appears to degrade or leach after a short period. It’s extremely disappointing for a product that advertises "purity" and positions itself as premium. This has all the markings of planned obsolescence — filters that degrade prematurely, pushing users to purchase replacements more frequently than seems reasonable. Whether intentional or due to poor quality control, the result is the same: a product that quickly becomes unusable and creates more waste. What’s worse is that ZeroWater doesn't clearly warn consumers that this could happen or provide transparency about lifespan under real-world conditions. A filter that turns your drinking water fishy after 2-3 weeks? That’s unacceptable — and feels like a disgusting business practice for a product that's supposed to improve health and sustainability. Verdict: Avoid unless you’re prepared to replace filters constantly — or tolerate water that tastes like a fish tank.

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 to do is sell you the filter basket, it will fit both old and new generations. So product is good but bean counters reign at Culligan.

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 this new unit. TY Culligan and ZeroWater! Best there is, best there ever will be!

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 buy a product that actually works, but am not holding my breath.

Had this product for years. Although hassle, The purification method works. It’s provided to my dogs, as well as me. We have hard water. A skeptic by nature, I observed using the purified water in my glass kettle. The hard water deposits were NOT in the kettle. Better tasting beverages too. Keep my pitcher in fridge and serve water cold . So, im a believer! Worth hassles and expense for “healthier” water.

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

I so love mine ,use it all the time ,fill mine up every few days

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 months from 6 weeks to 4-6 to 3-4, and now 1.5-2 weeks. Less than 2 weeks is ridiculous.
