Review on Enhanced TIER1 Undersink Replacement Filter: Unbeatable Quality and Performance by Gabriel Tomato

I am so sad. I've used these filters for the last couple of filter changes but according to Discount Filters they will not be replaced again. Please look at the photos. Old model on the right. Left is new. The UPC and label are the same, but note that the "screw" at the top is missing the gap that holds the filter in place. Inside, the filters look completely different. The new one has a central plastic ring and a black gasket. When installed, the old filters do not flow. The new filters have a slight leak at the top, but when pressure is applied (tap closed) they slowly unscrew and make a huge mess.
