Product review (5 stars): no need to add water beforehand or anything else like other brands were asking to do
Didn't want to pay 45 dollars for the "official" filter so I bought this one. Was a little scared after the 1 star reviews but decided to try. Very simple to install (just screw it in place), no need to add water beforehand or anything else like other brands were asking to do. I have been using it for a week on my whirlpool fridge and the water tastes great, and water pressure is as high as it was when my original filter was brand new.
