Can anybody recommended a device for testing home CO2 levels? I tried to do a quick search, but there is a wide range of products across many price points and it's hard to make sense of it.
the most accurate readily available for CO2 seems to be the "Laser Egg+ CO2" for $200 https://shop-usa.kaiterra.com/collections/frontpage/products... which uses SenseAir S8 but looks and sounds a little silly
and the $150 "Awair Element" https://wiki.liutyi.info/display/CO2/Awair+Element+inside which uses the Amphenol Telaire T6703-5K
