Product review (5 stars): Received Aprilaire branded product in factory packaging
Arrived as described, Aprilaire OEM filter on Apriaire box.

The box has clear instructions and it skills to switch out this new filter with your old one. It's about as hard as cleaning the lint filter in your dryer- the difference is you just toss out the old filter and replace with the new. From start to finish, it takes about three and a half minutes.
