Product review (4 stars): Purge the filter or just buy the bypass ...
Recently purchased, i don't know how long this unit will last but I thought I could clear up some confusion on these.  Unit has to be purged after installing otherwise you will get this very nasty taste for gallons and gallons of water.  I ran about a half gallon of water through the dispenser, pulled the filter, and shook all the water out in the sink.  Repeated two more times, except dispensed about a quart out before pulling.  Bad taste gone.
I found this out by googling service websites, where i found that Frigidaire makes a bypass valve for these filters.  So if you don't really need the filter, just want the water flow, contact Frigidare @ 706-860-4110 and order part # 242294502.  $34, free ship.  You won't find that part number on their website btw, or that telephone number.  Took a bit of searching and listening to mood music for hours while i was on hold ...but worth the wait. ;  )
