PM2.5 is at 104ug/m3 indoors with an open window.
with an open window.
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.
Just tacking on that box fan filters are really easy to make and do a solid job in my experience. Use high quality filters (like MPR 1900+/Merv13+), duct tape them into a cube (air direction facing inward in my case) and duct tape it to the intake side of the fan, I use 4 filters with the bottom being a cardboard blank, but there's a ton of designs out there.
This is what I came up with.
There's a HEPA in the magic blue box. Closed off all other windows that could act as air intake. Turned on the bathroom and kitchen fans. They take air from the inside and exhaust it outside. We're doing ~600 CFM at the intake pipe. The HEPA is tiny in comparison to what a Corsi-Rosenthal box uses but it's compensated by having a high static pressure fan that can pull much more air through it. If it didn't work I was gonna go to CT to get some filters and a fan. :D

Do you mean it's somehow worse than sitting next to a burning fire?
We had a few years of fire smoke from 100s of miles away, I could not see the house across the street. Much different than sitting beside a campfire
Yes! A single camp fire can only put out so much wood smoke, but wildfires cause all the air around you to be saturated with smoke. The smoke can contain heavy metals and all other kinds of bad shit to breathe, because it’s not just dry wood the way camp fires are. The contents of any homes or cars that have burned are also now floating around in the atmosphere.
TL;DR: don’t breathe this
I don't like the things you're saying. 😂😔 I'm gonna look into a filter now.
I’m glad, stay safe! Grab some N95 or KN95 masks for outdoor use too while you’re at it 👍
I got a steady cache of Moldex 2600 for viral particulate reasons. 😂
Last night was bad (far east side of toronto... like Durham Region). It was over 180 and not only could I smell the smoke from inside the house, but my eyes were burning, too.
After closing the windows, the CO2 in here doubled. Lose, lose.
I can't imagine being <1000km away from those fires.

Having flashbacks to the fires from a couple of years ago. We were nowhere near (these were the Quebec fires IIRC) but outdoor AQI was bad for weeks, regularly topping 300 and peaking at 4-500. Had everything closed up, AC and multiple HEPA purifiers running, and it was still awful indoors.
Yeah, I remember that. We had HEPA filters running then, too. I couldn't go cycling during that time because of how bad the air quality was. Not good for anyone with sensitivities or lung/breathing problems.
All those buildings over the tree line should be fully visible.
Reaches 125 on the balcony.
That's downtown, indoors with all windows closed.
Looking at this week, it seems like today is indeed the worst day so far.
Is this Canada or HomeAssistant?

Actually, AQ Air is giving me 164 😬
