Product review (3 stars): Why the change from PUR filters?
Cheaper than old PUR replacements for Whirlpool filters, but I have had several failures with this filter. In order to get the water to flow to ice machine or water dispenser when water flow stops, I need to eject and re-install. Not sure why the filters were changed, but this has design issues not found in previous PUR filters. Waiting to see if I get the same life expectancy from drop filters when compared to PUR filters. I have not done a water test to see if the level of contaminants is better or worse that old PUR filters.
