Title: Did not fit
Review: I bought several of these, but they did not fit. I failed to notice the word "Aftermarket" in title, which apparently means that they are not really FAPF01/FAPF02 3M filters, but instead a filter made by someone else. They did not fit in my filters, and do not contain the same quality of filter materials as the original 3M Filters.
