Not really insane. The first rule of indoor air quality is to get rid of the source. For example remove the dirty diaper from the house. Don't try to mask the smell.

Insane new research. Scientists gave asthma patients free electric stoves to replace their gas stoves, then checked to see if symptoms improved. Not only did symptoms improve, ditching gas was *better than medicine.* Details in today's newsletter: www.climatecoloredgoggles.com/p/electric-s...

I have instructed 100s of people on making CR box air cleaners (corsirosenthalfoundation.org/instructions/). They are about $100 and easy to make (10 year olds can building them). Most importantly use air cleaners in a small rooms and close internal doors so the clean air stays in your room.
