Title: Pur Problem
Review: Others have noted an apparent quality control problem with the replacement filters. After a short while, well before the filter is due for replacement, the water takes hours if not days to drain through from top to bottom. It seems to be an issue with the activated carbon in the filter, which appears to break down and block the outlets. Shaking the filter restores operation but only temporarily. Too bad, because this was a good product. However, the filter problem renders it useless. I would recommend trying a different manufacturer.
