#Aranet PM, CO₂, radon monitored. Windows cracked = radon low. Closed = yikes 😬. Radon pump on hand, not installed. No rush. Heating bill? $75/yr (USDA wood permit). EPA-certified woodstove, dead Uinta NF trees put to use instead of rotting into CH₄ + CO₂.

Why let bad air build up in the first place? It should be a steady constant cleaning and filtering. It is not like trying to determine when your soapy kitchen sink dishwater needs changed. We keep our windows cracked open 2 cm and run air cleaners all day. HVAC is not on auto but runs continiously
