The filter fit. It will be six months before I can tell if there is any problems, and it is not so clear I could tell then.

All filters are not the same size as on the box

Unfortunately, I did not realize there is a difference in the width even when it says one size. The filters I ordered were 20X20X5 but were really 20X20X5 1/4 and do not fit. The one the furnace servicing company sold me was actually 20X20X4 3/8 and I didn't realize the difference until I went to change the filter at 4 months, as I was instructed. A word to the wise.

My husband suffers from severe allergies, the first night with this filter we were able to get some decent rest.
