I love products that are regulated, like water filters. You can look them up and verify that they meet specifications that make a difference. Right now, I prefer the Brita Elite. Refills available everywhere and it makes my chlorinated tap water taste clean. (Not the same as regular Brita). I tried about 40 brands over the years. Brita Elite is the first one with no drawbacks that make me want to keep looking for something better.
