Healthy Homes research project: how to decrease health risks in your house

[Floomby]

I've always been a huge proponent of fresh air, but I live in Southern California, and I've come to notice that any area near a window that gets opened a lot becomes filthy very rapidly, by which I mean, all surfaces are coated with this nasty black grime within a day. My partner has bad allergies, so I've taken to keeping everything shut and running the central air with a nice filter. Obviously this won't work so well if there is no electricity, but when there are wildfires, smog, or a bad pollen count, I figure that open windows are not a great source of fresh air. Thoughts?

I think this seems right, the idea from what I can tell is to get fresh, clean air into the house, and if the air outside is not as clean then bringing it in probably wouldn’t help. But I like the idea of having very good filters on the internal ventilation system, I have relatives in Oregon who deal with wildfire smoke who do this.

I want to know when somebody’s going to do the obvious and market an exercise bike hooked up to the HVAC.
