Well said. I'm not the first to say it, but: common sense ain't so common.

Here's some recommendations from our household, related to my previous battles with mold-related illness:

RabbitAir hepa-level air purifiers. Pricey, but worth it.

Dr. Bronner's soaps. We use them for showering, washing hands and dishes. No dishwasher here; our son has taken responsibility for it, in exchange for our fascilitating his chess-oriented lifestyle.

7th Generation laundry detergent. Unfortunately, we have to use a public laundramat, so we're getting some of the polluted stuff washing through the machines' detergent/softener resevoirs, but the poor have no choice.

We keep the windows closed during rush hour timeframes, and I keep watch on wind directions and know where the fresh air comes from.

We also try to get out into green space away from traffic and get a walk in or just let the teens knock the soccer ball around a bit.
