    On the 2nd Generation Prius, does air pass through the cabin air filter when on recirculate mode? I assume that outdoor (fresh) air goes through the filter from the detritus that collects in there. I'm asking because I want to know the fastest and most efficient way to clean cabin air when smoke or car exhaust gets inside.

    yes, the fresh air intake is above the filter, and only closes about 80% on recirc iirc

    Thank you. To be clear, are you saying that the portion of the air that is recirculated also goes through the filter (not just the fresh air)?

    correct. when you set it to recirc, it all goes through the filter, but you are still getting some fresh air mix.
