It may seem like an overstatement, but these are the worst water filters I've ever used and they're essentially useless. But maybe I just came across filters from a bunch of inferior filters. I've had a water filter for decades and have used both the hard fiber and thread types (like this one). I've never had any problems. But they just don't fit in the filter canister, they lean back and fall to the side and don't snag on the top port. In other words, they won't be stuck in the canister no matter how carefully you handle it and screw it into the filter housing receptacle. The first sign something was wrong was when I noticed that the first one never got dirty. I suspected that it might have leaned forward and didn't snap properly into the top inlet of the filter housing, allowing water to bypass it, although this has never happened to me. Naturally! That's exactly what happened. I removed the old (clean) filter to inspect and decided to put in a new one even though the old one was as good as new. I spent 45 minutes screwing the canister onto the filter connector without pulling the filter tip out of the way and out of the water. 45 minutes after this filter tipped over and leaned against the side of the filter canister as I carefully screwed it in, I gave up. My wife said she wanted to try it, so I told her to go ahead. Twenty minutes later she too has given up and is going to the store to return her as I write this. The ends of this filter are different. One has an inner plastic tube that sticks out a bit and the cord overlaps the other end of the tube. Logic will tell you that this end should be such that it acts like a funnel to center and hook the inlet onto the top of the filter housing, although I've never had a filter that goes in with a specific end up had to, but after inspection I tried to install it with the end of the funnel. Vain. I've tried the other way, also without success. I'm just lucky that my filter holder is clean, otherwise I would never realize that this filter keeps flapping to the side and not getting caught in the inlet. I don't know if it's just a bad batch or what. As I said, I've used both types of filters - solid and "filament" and I never had a single problem until I got them. If you have a clear housing, carefully inspect after screwing the canister into the top of the filter housing. Look from all sides. If it's tilted to either side, it won't filter the water. If you replace that filter and find that it's almost as clean as new, you'll find that it was tilted to one side and not filtering the water. I suspect there are many people using this filter who don't know it doesn't work. My wife and I tried unsuccessfully to install the filter for over an hour and we both gave up. . This is possibly more time than I've spent replacing ALL the filters in decades and we could never get the filter to stay upright. It just wobbles and falls to one side of the canister when you unscrew the canister. Very frustrating. All of the other filters I've used over the decades, both cord and solid fiber types, stay fairly stable in the filter housing so they don't dangle or fall off the side of the filter when screwed into the filter receiver. Working with this is like trying to balance a coin on its end on a plate and then walking around with the plate and turning around without letting the coin fall on its side. The only thing I can think of is that the plastic cylinder that fits over the short post at the bottom of the filter canisters is wider than the other filters, so it doesn't lock down enough to hold the filter steady when grabbing hold of and screwing the filter into the canister pickup. Update: My wife just got back from Menard's in Naperville, Illinois where we bought it. Even though we paid over $30 for ten of them, Menard's only refunded 1p each! They said they had a coupon sale at one point for 1 cent each and would only refund an amount equal to the lowest price they've ever sold at. My wife then asked if she could swap them out for similar hard fiber filters that cost less than strings, and she declined as well. So my wife just threw them in Menard's trash can. I have no doubt that Menard's will put them back on the shelf and sell them to another unfortunate person. (Of course, this isn't a review by Menard, but I just thought I'd mention it.) Pros: My wife took a hardboard, also made by Omni, and I put it in and it filtered. Water literally within 20 seconds. Like all water filters, it stuck to the bottom of the filter canister and didn't tip over when I screwed the canister in.
