How to find an air sensor for fireplace smoke?
I have neighbors that use their fireplace from time to time, rendering the air around them unbreathable if you care about lung cancer and other respiratory ailments. I'm hoping to convince them to cease but its hard when people are used to doing something they enjoy and it saves them money in heating costs. I thought if I could show them air quality readings it might help a lot, especially if they were concerned a little themselves. Am I looking for the PM2.5 reading? Something else? So many air quality devices are concerned with dander/pollen/allergy issues. I couldn't care less about those. Just smoke. I thought if all I need is smoke detection the cost might be much less.
