So when I bought my jug I got "normal speed" pure filters, they took a while but it was ok. After about 3 months it stopped filtering water completely (I suspected it was clogged but that took a while). I bought the quick version of Pur so I didn't have to wait long for my pitcher to be full. It was fine for the first week but now I'm on my second week and it won't filter the water unless it's over the "T" part of the filter and even that barely works now .
