I have an old Pur water filter pitcher so it's difficult to find replacement filters on store shelves. They fit as they should and although I rinsed and soaked with water first, the first two jugs of water still had a bad taste reminding it's time to change the filter but after that the water was fine - so I know it works, it goes through a "warm up" phase. The tap water in my area is safe, but it can have a slightly musty taste and stale smell. I've been using the Pur Filtration System for years and have always been very satisfied - glad I can still get these filters as I drink a lot of lemon water and boil water for tea almost every day.
