Product review (4 stars): easy installation
I installed this on my Whirlpool refrigerator. Installation was very easy. Just open the filter door on the fridge, the old filter pops out. pull the old filter out and insert new filter. Close filter door. Then flush 4 gallons through get rid of any trapped air. 6 months lifespan is probably conservative unless you drink a ton of water. I plan on keeping for at least a year before replacing.

Price was better on Amazon than home depot
