ZeroWater Official Replacement Filter - 5-Stage 0 TDS Filter Replacement - System IAPMO Certified to Reduce Lead Chromium

Great filter, preforms as advertised. We have been using this filter for over 5 years. We are completely satisfied with how well it removes the hardness. It greatly improved the taste of our coffee. Read more

Hands down the best water filters you can buy. See the Project Farm review. I was going through two of these filters every 2-3 weeks (running them in parallel), which was getting expensive. But our water was always undetectable on my Apera TDS meter after running through ZeroWater filters. Our tap TDS is 350. I bought an Express Water RO+UV, which lowers the tap to about 12-15 TDS, then I polish it with dual ZeroWater filters in parallel. Now they last months. I still replace them every 2 months, even though the water stays at 0 TDS the whole time. That puts me at 1 box of 12 per year. And our water is perfect. I love the taste (or lack thereof) of 0 TDS water. I use it for my distiller (for CPAP and NasalFresh MD), which never needs cleaning. Tea, coffee, and pasta have more taste because the water is so pure. And everything I put it in stays spotless. This is how you do water. Even my dogs love it. Read more

One of the few times I have been disappointed. The filters did not perform as well as usual on my last purchase. 2 were defective, did not produce clean water at all ,the water stayed dark and cloudy in the pitcher had to throw them out and one filter lasted only half the time before water would not go into the pitcher and the water tasted foul. First time that happened over several purchases of otherwise reliable filters. I really need these because of the poor quality of water in my area. Read more

This is the only filter thar removes lead, or at least reduces it. Brita doesn't. This is my go to water filter from now on. The water tastes cleaner and the price of the filter is worth it! Read more

I test my drinking water often. These filters are a bit costly, but they keep my water cleaner than the less costly ones for longer. You don’t have to replace them as often. Read more

I used the zero water filter for about a year before moving and getting a different water filtration with the house we bought, and I’ve got to say, it was wonderful. The water tasted great and the filters seemed to do a good job. They filter pretty quickly too. The ONLY thing. You MUST replace the filters somewhat regularly if you are refilling your tank multiple times a day. Don’t go over 1-2 months or your water will start to taste like lemon and that is bacteria!!

😱😱😱 I absolutely hate to leave a 1 star review because I have used Zero Water products for more than 10 years with absolutely ZERO issues....until now! As I stated, having more than 10 years of top notch performance from all the pitchers, large containers and genuine Zero Water replacement filters, I am extremely knowledgeable about Zero Water and how well it's worked for us for more than a decade. We wanted a larger container to add to our plethora of pitchers and various sized containers, so we opted for this large 52 cup model. It does hold a great deal of water and we loved the idea of it using 2 filters at once because we go through about 5 gallons of water daily for just our family of 2 plus our furbaby. I cleaned the 52 cup container and it was easy to snap in the spigot and the TDS meter, making it ready for filling and filtering. It does take a while to allow the filters to properly filter the water, which is a good thing since it would be quite useless if it ran water through the filters quickly, as that would be indicative of poor filtering IMHO. All together, to fill the entire container full, it probably took a little over an hour which was fine. I went to fill my morning glass water bottle and as I approached the unit, this absolutely 😱HORRID, MUSTY, FISHY, MOLDY 😱 smell just reeked! I didn't even fathom it could be the new Zero Water container water, so I looked and sniffed around trying to find the source. To my absolute HORROR, that putrid stink was in fact coming from the brand new Zero Water container with brand new Zero Water filters! WHAAAT 😱🤔🧐🤷‍♀️Yep, the filtered water from the BRAND NEW 52 CUP unit with BRAND NEW ZERO WATER FILTERS, it was emitting THE most awful smell that's even hard to describe other than musty moldy rotten raw fish stink😱 Our tap water tests between 80 and 110, which is not bad at all, but we always get about 3 to 4 months out of each genuine Zero Water filter. Every Zero Water product we have ALWAYS brings our tap water TDS (Total Disolved Solids) level down to absolute ZERO (000 on the TDS meter). We change the filters faithfully when the TDS level reaches 006 in whatever Zero Water container or pitcher it's in. I have been on autoship of genuine Zero Water filters for many years, so we always have genuine Zero Water brand filters fresh and on hand when they're needed in one of our 6 different containers or pitchers (7 total now with this new 52 cup container we just received). I tested the tap water, it was reading 091ppm (parts per million) on the included TDS meter. I tested the tap water again with another TDS meter (we have several) and it too showed our tap water at 091ppm. I then tested the stinky fishy water that had JUST filled up the night before from this new 52 cup container, which came with 2 Zero Water filters and we selected the bundle deal to get extra Zero Water filters, so we had 6 total Zero Water filters with this new container since the container itself automatically comes with 2 Zero Water filters inside the box. So I tested the stinky fish water and I was in total shock 😲😱 because the newly filtered water had a TDS reading of 247ppm!! 😲🫢😲😱 HOW IS THAT EVEN POSSIBLE WHEN THE TAP WATER GOING INTO THIS BRAND NEW UNIT WAS 091???!!! 😱🤷‍♀️🤔🤯 The filtered water coming out after filtering was almost 3 TIMES the level it was going in!! HOW?! 🤔🤷‍♀️🤯 So I emptied out the entire 52 cup container of filtered water and I tried again with the same 2 filters that came with this new large 52 cup container. After waiting and allowing it to filter and finish filling up the container completely, I again was in disbelief and shock 😲 because the same rancid disgusting fish smell was back. This time the reading of the filtered water was over 300ppm at 316ppm!! HOW???!!! 🤔🤔🤔🤷‍♀️ So I threw those 2 Zero Water filters away that came with the 52 cup container and I used 2 of the 4 Zero Water filters that I received with this new bundle. Same process, fill and wait. The nasty fishy smell wasn't AS BAD but it was still sickening! The filtered water in these 2 newly installed filters tested at 193ppm. I wasn't about to use the last 2 filters that came with this selected bundle, so I went to the closet and got out 2 of the Zero Water filters I had on hand from my many years of being on autoship of genuine Zero Water filters. Wouldn't you know it, those filters I had on hand worked like they're supposed to and the same tap water filtered down to absolute ZERO (000ppm) just like we've always been accustomed to! I don't know how or why the Zero Water filters that came with the 52 cup container (and the 4 extra filters bundle) ended up with TDS readings like they were, but obviously something somewhere 🤷‍♀️ happened to the filters since my Zero Water filters I had on hand worked like they were supposed to, making super clean smelling AND tasting ZERO WATER with 000ppm! I have recommended Zero Water to numerous friends and family, and I have turned so many people into fellow Zero Water supporters/fans but I must say I'm quite leary to keep doing so if this is the type of filters that are now being put out by Culligan. Sure, flukes happen all the time with production of ANY item, but to have brand new sealed Zero Water filters cause tap water to turn into rancid fish water at nearly 3 times the TDS pollution level AFTER Zero Water filtering, that's totally unacceptable! I ALWAYS make sure that my Zero Water filters are in their factory sealed bags, otherwise I would not use them. I have never had any of the Zero Water filters from my autoship subscription to ever be opened, torn or not work as intended, bringing our tap water TDS levels down to absolute ZERO (000ppm). I'm still baffled 🤔🧐🤷‍♀️🤯 AND DISGUSTED 🤮 at the smell and super high TDS level of the newly filtered water 😱 Sorry Zero Water, I've lost faith in what I had been a faithful customer of for over a decade! ONE bad Zero Water filter is a one-off, 4 bad Zero Water filters.....there's a HUGE HUGE HUUUUGE problem somewhere on your end. I won't even consider using the remaining 2 Zero Water filters that I got in this bundle since 4 of them have already proved to be defective and dangerous TDS levels! I assume the only way that could have happened when they were all in factory sealed bags is exposure to some kind of contamination along the way (Truck exhaust?, Warehouse storage issue?, Old filters?). Baffling 🧐🤔🤷‍♀️ and a HUGE LOSS financially with 6 wasted/bad Zero Water filters (those genuine Zero Water filters aren't cheap by any means!). 😱😱😱 USE WITH EXTREME CAUTION DUE TO ZERO WATER TDS PPM FILTER ISSUES AS STATED ABOVE 😱😱😱 Read more
