I purchased the "new model" Pur 2-stage filter without the U-shaped usage indicator. I was very interested in the "change" in design and how it affected usage. I use the Pur water pitcher in a very unusual manner that is NOT typical of most users. Firstly, I use a Premium 10-Stage water filter manufactured by Enviro-Products as a pre-filter for my little Pur 2-stage water pitcher! I only water run through the little Pur Water Pitcher because I think that the final product that I get tastes a little better that than when I don't use it. It's very subjective, but that's how I feel! I have run the old Pur Filters with the U-indicator on a daily basis for as long as a year without replacement. Obviously, I would not recommend this for anyone, but understand that it ONLY sees pure pre-purified water. After purchasing the "newly designed" Pur 2-stage filter I noticed that after approximately 60-days, water flow was being significantly reduced to a point where it was alarming to me. I couldn't be a matter of the filter media being clogged because it ONLY sees perfectly clean water. We'll out comes my little Dremel cutting tool, - - and I carefully remove the top dome in a effort to determine the source of the problem. Low and behold the whole top section of the filter is crammed with a product that appears to be Cellulose fibers similar to what you would find in a single stage filtered cigarette. Anyway, Pur is using this cellulose type product as a "roughing filter" or strainer before the water reaches the lower filter media. The fiber, whatever it is, has swollen to the point where it will no longer past ANY WATER. How about that, - - a couple of months of use and the water filter is useless! I further checked on the technical attributes of Cellulose fibers and discovered that they have a strong affinity for water and that they swell up when exposed to water and then shrink when allowed to dry out. I find it particularly interesting that Pur would choose to use a cellulose type filter as a roughing filter (and clogging agent) in front of the other media within their device while full well knowing that it would eventually choke off the water supply to the filter in a relatively short period of time and render it useless! The only thing that's left for you to do with your clogged filter is to go out and purchase another one that will also clog in a short period of time. I really feel sorry for the "poor Pur" people and all the new replacement filters that they keep selling to uninformed consumers. ie. "suckers" Shameful, - - really shameful. Yes, I'll place them on the "Wall of Shame". One Star! I've made modifications to my Pure 2-stage filter, but that's another story!
