You can get a pretty cheap sensor that works well. I got a laseregg.
Indoors was consistently better for outdoors for pm 2.5....except when cooking. Then, pm 2.5 is often 20-100x worse. Exhaust fans help but are not nearly sufficient. Often opening all windows is required to even get the number down.
Co2 is higher indoors, you can measure that with a separate sensor. It is a proxy for various VOC’s which are harder to measure directly with consumer available devices.
- phyzome 6y agoCooking will reliably send CO2 over the 3000 ppm threshold that my sensor can detect and report. I always use the extraction fan now.
- graeme 6y agoCo2? You must have a gas stove. Note that this effect doesn’t apply to stoves that don’t involve directly burning carbon. Normal cooking produces pm 2.5 but not co2.
- phyzome 6y agoYep, natural gas. I feel so mixed about it. I grew up with electric, and the responsiveness of gas is wonderful. But piping an explosive substance into the house such that a leak can destroy this house and the neighboring ones is pretty dodgy! I think there's something to be said for its energy efficiency (it doesn't suffer the same transmission losses, right?), although of course if you can get electricity from renewables, electric is better. Best would be having a local biogas digester. I find it a little silly that you say "normal cooking" doesn't burn carbon. Normal cooking is over wood fire, don't you know. :-)
