Product review (5 stars): Perfect replacement for our LG fridge
Bought this to replace the filter in my fairly new LG fridge. It's fairly straight forward; the instructions to pop the old one out are printed on the box that this filter comes in. You open the cover, pull it down, and then it pops right out of the fridge. Pop the new one in, push it upwards into the filter cover, and shut the door. It requires no tools other than your hands and only took me about 60 seconds my first time doing it.

After the new filter is installed, don't forget to do the last step in the instructions, which is to run 2.5 gallons of water through the fridge water dispenser and discard it. 2.5 gallons is actually quite a lot of water (about 5 straight minutes of water pouring out of my fridge) and may be overkill, but I didn't want to risk it and still followed it as they said. You can clearly see in the first couple glasses worth that you discard, that the water is a little "grainy" looking as the filter cleans itself out. After all is said and done though, the water is perfectly clear and tastes great.

All in all, I guess this is a 5 star product since it works as expected and is well designed for ease of use.
