Nice, thick charcoal filters
I have a Holmes F220, which requires a filter and pre-filter that don't really eliminate kitchen odors, so I bought these, thinking they might be about the right size and eliminate the smells when the windows can be opened. They're the wrong shape and a bit thick, but I cut them to fit, so that each "pre-filter" is made of 1 1/2 of these filters. It seems to eliminate cooking smells, but I haven't yet done any serious cooking with the windows closed. They're a nice, thick charcoal filter of good quality, but just weren't designed to be in the F220. I think they'll do the job, despite being jury rigged.
