What do you do for fresh air? We have a very well insulated cabin heated by fire, but find the CO2 builds up, particularly overnight with no doors opening, and if we aren’t very quick to close the fire once it gets going, PM2.5 can jump quickly.

We sleep with the window open in the bedroom, and I air the place each morning. Also, it’s almost too well insulated, as it’s easy to accidentally make it 30C in here while it’s -9 outside - so more often than not we have a window cracked open for some air whilst sat in in the evenings. Our PM2.5 is often a silly number, same reason. I’m considering getting an air purifier, but to be honest, given all the crap I’ve inhaled whilst building the place, and given that I smoke anyway, it’s low on my list.
