From a fellow resident of an area with frequent fires… Friend, close the window 😬 You don’t want to be breathing it! Wildfire particles are very tiny and will lodge themselves in your lungs. Do you have air purification going? Please be careful and take care of yourself.
Here are my readings for my outdoor Airgradient Open air and indoor Airgradient One.
Doors and windows are closed since yesterday afternoon and my HVAC uses MERV 13 carbon filters. I have set the fan to run a bit faster in order to filter out more PM. You can also turn off the air exchanger a bit but you need to keep a eye on CO2.
