I love having access to a filter for PFAS since my area in Michigan has had a LOT of these chemicals discovered in drinking water. I love how quickly I get my filter after I order it, and I love that it works in a Brita pitcher which is super easy to find. I also really appreciate the recyling program for used Cyclopure filters. All in all, I'm really happy with Cyclopure.
