This week we've had heat,
and smoke from fires,
so we had the AC running at night for the first time,
and it was pulling in some smoke

the outside AQI was 160 for PM2.5 last 2 nights
which is about 7 cigarettes per day worth of PM2.5

the air was leaking in through the front door
and furnace door , so both had to be gasketed with garbage bags,
using a credit card

I started sealing with ducktape around the outside of the door frame,
but that wasn't gonna last,
and it was kinda clumsy and slow to deploy

front door had weather stripping gasket job from years ago,
which worked good enough against occasional winter time high winds,
but it was never tested against the AC like this week
