I bought PUR Water Pitcher Replacement Filter - 3 Pack 4 months ago. Water runs through the filter with the same speed as on the first day. It looks like such a filter can be used forever. It's a miracle, it can save tons of money! On the box is "Distributed by Kaz USA, Ink, a Helen of Troy Company", so all the other companies are going to bankrupt. I can't believe Target sells such junk. Target does not care about its reputation of the retailer? They do not value their name?
