Input: The carbon filters are too large to sit as they should without curling or bulging inside the HEPA filter. There is a gap at the top of the HEPA filter itself, which makes me wonder how much air is passing through unfiltered. I would not recommend these as an alternative to the normal filter. I have not noticed any strange odors as some reviewers have reported.

The carbon filters do not fit into the HEPA filter
