I have an AirVisual Pro, which is quite expensive, but my half finished air quality monitor project had been on the bench for much too long. I have windows open all the time, air conditioning on too often, and dehumidifiers and HEPA filters as well. It is not efficient or particularly environmentally friendly... but I want a CO2 level My next half baked idea is figuring out a way to have a sealed home and an applianc…

Bubbling air through quicklime slush is an easy way of removing CO2. You can turn the calcium carbonate that forms back into quicklime by applying heat. But it's probably better if you invested into a counterflow heat exchanger for ventilating your home. You can recover a large part of the heating/cooling energy.

I have a cheap pm10 meter and ran it continuously for a few weeks. Next too cooking meat the other activity that stood out was blowing out the birthday candles. The pm10 rose to 300 and only was backs to healthy levels (below 50) several hours later. I was as surprised as you are. Next time I'll definitely open a window

Not all particles are equally toxic. If I had to guess, the smoke from a recently-extinguished candle is probably condensed wax vapor rather than PAHs and heavy metals.

The biggest pitfall I see with this is we’re extrapolating from large doses of air pollution to very tiny ones. Clearly we have enough evidence to say that smoking a pack a day or living in a smog-filled city will cut years off your life. But we would need truly gigantic samples to show that blowing birthday candles or broiling fish once a week will cut weeks off your life. Instead these conclusions are being derived…

Could you give some citations for studies on radiation workers? The permissible doses in most countries are extremely low and there are not that many people working in the industry. This makes me wonder they manage to achieve statistically significant results.

Is there any evidence that people who live in areas with better air have better health outcomes overall? Hong Kong average life expectancy is 85. Iceland is 83. Hong Kong has poor air quality and Iceland has some of the best. I'm for better air quality but it's just part of the puzzle.
