Product review (4 stars): Perfect fit for my Whirlpool refrigerator
Perfect fit for my Whirlpool refrigerator. Always feel more comfortable purchasing OEM. The filter does always have a little bit of charcoal residue when you take the temporary seal off in preparation of installing it. I always rinse it off before installing. Simply open up the housing inside of the refrigerator (fridge, upper right in my model). Begin by untwisting the old filter counter clock wise, then twisting on the new one clockwise. Then just find a large container and start filling it up until the water starts coming out smooth and clear. You are back in business.
