The replacement filters are ridiculously expensive at something like $75 each for the paper/charcoal combo. As far as the automatic outside/recirculated air switching, it does seem to work. It is pretty unobtrusive, and the only reason I know it works that way is that I looked it up in the owner's manual when it seemed to be switching to recirc mode randomly. After reading the owner's manual, I noticed that it switches to recirc when I'm behind a diesel or an oil-burning car for any length of time, like sitting at a red light. Yes, I'm guilty of not reading the owner's manual, but the manual for the car is something like 400 pages long with another volume several hundred pages long for the navigation system so I tend to only look at it when I can't figure something out on my own. I'd hate to diagnose or pay for repair parts if the system breaks, but so far, it has been trouble free. -- Ray O (correct punctuation to reply)

They would use charcoal impregnated filters that had 6 grams of carbon, for example. That was why we got into the Austin Air models for the house and car. ( I have NO financial interest in them! ) We have 3 of their HM400's in the house and they have HEPA and about 17 lbs of carbon media ( dont recall if there was purafill in them too ). The HM200 that I mounted a seat belt bracket on top of, and put behind the drivers seat of the Corolla, and run off an inverter, has about 7 lbs of charcoal in it, and really helps how we feel when we drive. Needless to say, ANY filter is useless if someone smokes in the car and we're both non-smokers and only drive with the windows closed ( otherwise it also would render a filter useless ) and the vents shut ( recirculate ). In fact with the 2002 Corolla we just bought, I noticed I was getting sick on the drive home and figured out how to put it in recirculate mode. Seems the button light has to be on, for it to do that. I figured it out by turning the AC fan off. When recirc was off, the vents were open and air was coming out of the vents anyway, even with the AC fan shut off. And I could smell the outside fumes from traffic. When I pushed the button so the light lit up, the air stopped coming out when the fan was in OFF mode, so the vents must have closed then.
