Product review (1 stars): Filtered water tasted weird!!!
Unlike the ones made by PUR , water filtered through these filters tasted somewhat salty and bitter, and gets worse as time goes by.  Ended up threw away the other 2 filters.

UPDATE - Received response from vendor, asking me to "first please run water from the dispenser for 5 minutes about 3 gallons to clear the system and prevent sputtering. And then please reinstall it according to the illustration."  I had ran at least 7 gallons of water from the dispenser through the filter during initial install, using an 1-gallon milk jug, so I am pretty sure that's more than 3 gallons of water.  And, I seriously doubt that removing and reinstalling the filter would fix the problem......

Used to buy the Maytag branded filter, which was made by PR.  Even though it costs some $30 each and it's harder to find now, at least I know its quality.
