Product review (2 stars): Make sure you have the updated water filter housing bracket or you're in for a mess and a headache
Some modification between one or another series of PureAdvantage water filters from Electrolux changed the way these are seated and held in.  Older model fridges sans some update Electrolux is supposed to offer for free, cause all sorts of headaches.  Make sure your fridge has the current/updated version for the water filter housing/bracket in the fridge-side mount, or you'll have these things popping out and shooting water everywhere when you open the door.
