HEPA Filter, uh, filter: AskMeFi is awash with general references to HEPA filters. How about some more specific advice? My books, which really own the house, would like a HEPA filter for the main library (11 x 22). I've been looking at the various Kenmore brands, for starters, as well as the usual consumer ratings sites. Price is a moderate object--a whole-house filter is out of the question right now, but a room-size portable can be done. Any recommendations from experience?
