Product review (1 stars): Shorter than OEM
This filter is slightly shorter than the OEM Pur Filter 4.  The filter door in my Maytag fridge depends on the filter being the proper length to secure it when pushed up into position.  If the filter is too short the filter does not wedge itself into position and consequently rests on the filter door.  The fastening clip on the filter door does not lock firmly enough to secure the EcoAqua filter resting on it.  Consequently I had to fashion a wedge to fit on the end of the EcoAqua filter to secure it when pushed up into position.  I just installed the filter so I have no opinion how well it filters.
