Product review (4 stars): good stuff
I have been using pro pure fluoride filters for the last 8 months. They do run about 6 months as the description says. Sometimes it seems they are painfully slow, but I use 2 of the pitchers and fill water cooler bottles out of them. I keep 2 5 gallon bottles and one 3 gallon bottle filled with just these 2 pitchers all the time. While one bottle is on the cooler I fill the empty one. After I got them all filled I have never ran out. You have to clean the filters periodically with the provided sponge. The amount of sediment I find in the bottom of the filter reservoir is amazing and that's even after I fill them with filtered water from my refrigerator most of the time. They are in fact slow, that's why I gave them 4 stars but the water tastes and looks very clean.
