10 Cup Water Filter Pitcher, Blue/White

😱😱😱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 2 pound furbaby. I cleaned it 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! WHAAAT 😱😱😱 Yep, the filtered water from the BRAND NEW 52 CUP unit that just arrived yesterday and I just set it up the night before, it was emitting the most awful smell that's even hard to describe other than musty moldy rotten raw fish smell. Our tap water tests between 80 and 110, which is not bad at all, but we always get about 4 to 5 months out of each Zero Water filter. Every Zero Water product we have always brings our tap water TDS level down to absolute ZERO. We change the filters faithfully when it reaches 006 in whatever container or pitcher it's in. I have been on autoship of 12 packs of genuine Zero Water filters so we always have them 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 91. Tested tap water again with another TDS meter (we have several) and it too showed tap water at 91ppm. 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 got the package deal to get a extra Zero Water filters so we had 6 total filters with this new container since the container itself automatically comes with 2 inside the box. So I tested the stinky fish water and I was in total shock 😲 because the newly filtered water had TDS reading of 247ppm!! 😲 🫢 😲 HOW IS THAT EVEN POSSIBLE WHEN THE TAP WATER GOING INTO THIS BRAND NEW UNIT WAS 91???!!! 😱 The filtered water coming out was almost 3 TIMES the level it was going in!! So I emptied out the entire 52 cup container and tried again with the same 2 filters that came with this new large 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 300 at 316ppm!! HOW 🤔 So I threw those 2 filters away that came with the 52 cup container and used 2 of the 4 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! 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 filters I had on hand from my many years of being on autoship for 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 just like we've always been accustomed to! I don't know how or why the filters that came with the 52 cup container and 4 extra filters ended up with TDS readings like they were, but obviously something somewhere happened to the filters since my 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. Sure, flukes happen all the time with production of ANY item, but to have brand new sealed filters cause tap water to turn into rancid fish water at nearly 3 times the pollution level AFTER 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. I'm still baffled 🫢 AND DISGUSTED at the smell and super high 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! 1 bad filter is a one-off, 4 bad filters.....there's a HUGE problem somewhere on your end. I won't even consider using the remaining 2 filters that I got in this bundle since 4 of them have already proved to be defective and dangerous! I assume the only way that could of 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 HUGE LOSS financially with 6 wasted/bad filters and those genuine zero water filters aren't cheap by any means! However, the 52 cup container itself is great!
