I know there's a smoke situation going on and that filtration is the only possible solution to such smoke. However in the general case I do not want to breath filtered air in buildings, I want fresh air, straight from outside, ideally coming through the nearest window with a screen in front of it to filter the bugs and nothing more. There are two big problems with doing this: allergies and temperature. I think both of these problems are resolved when you simply acclimatize people to outdoor air. Maybe people spend few years uncomfortable until their body gets used to it (and until people learn how to dress appropriately for the season) but in the end we'll all be healthier if we're breathing fresh air instead of stale recycled air.
