We have used Culligan filters for many years. The redesigned D-30A has improved filtration, but the pressure has been significantly reduced, similar to the pressure reduction of the old D-40 filter. Today we see many inferior fridge water filters listed at Revain and elsewhere. Fake filters usually don't actually filter and have an open water bypass. Found out by opening a few. Good filtering is too important to use fake filters.
