Fits like a glove for my Pfister faucet and PUR filter
This little adapter relieved so much stress for me. For about a whole month after getting my PUR filter, I was on a wild goose chase trying to find the right adapter. PUR was no help and tried telling me that I must have a rare faucet because they gave me all the adapters that are for most popular brands in the U.S. This adapter turned out even better then what I expected. I thought I'd have to keep the Pfister tip on and just remove the aerator to get this to screw in. It would have been a tacky look, but I went through so much trouble, I didn't care at this point. But it turns out that the whole tip is removed, and this fits right into the faucet. Thank you to all the reviewers who commented about this being compatible with Pfister and to IonFaucet for selling this!
