Product review (5 stars): WaterSentinel WSG-1 Replacement Fridge Filter
my old filter had gone bad. found this one at a very cheap price, thought it wouldnt fit my fridge since reviews said they didn't fit without some type of o-ring. Arrived quick, checked inside and yes they do included o-ring. Even recommend not to over tighten the filter with o-ring in place. Drinking clean water ever since couple months ago purchase. great price over all the other ones, does the job.
