Two years ago, I participated in a rocis.org study cohort. It was very informative. Participants are given a collection of monitors (particulate, CO2, radon, and one other I can't remember). We are given three air particulate monitors. participants collect the data and send it back to rocis.org. Here were some of the main takeaways personally. Note that I live in Pittsburgh which doesn't have great air. A. The idea that you should "open your window to let in fresh air" is false. The outdoor air is 10x worse at my house and I don't live it a "polluted" neighborhood but in the burbs. B. Monitoring is very insightful. I put one monitor outside, one in the living room, and one in my bedroom. The outdoor air like I said was 10x worse than indoors. Indoors wasn't so great either. I replaced my furnace electrostatic filters with quality HEPA filters (they make box filters the same size as electrostatic panels and they are beasts). The indoor air quality improved by about 30%. I added a Blue HEPA filter to the bedroom. It runs continuously at the middle fan setting. Bedroom air quality improved by about 50%. C. Cooking is the biggest contributor to indoor pollution. When you monitor in real-time this becomes obvious. Induction is the way to go. Of course, the high-end appliance manufacturers are going to continue to make you covet that gas range. But if you're building or renovating a kitchen, go inductive.
