Turning off the HVAC is remarkably misguided. You want to run HVAC, in recirc mode (close any outside air dampers), and keep running air through your filters.

Any tactical filter upgrades you can do (e.g. putting HEPA filter cartridges in) will of course help too.

If we had just raked the forest, it wouldn't be so smokey.

Some people say.......

Someone told me air in PV is considerably better than lower elevations like Menlo or Palo Alto can someone confirm if this is true. And also is that why PVSD did not cancel class Friday??

Was in PV the last couple days and some folks said they thought it was better up there. I think they're crazy.

Granted, due to the proximity of trees and ridge lines (thus obstructed/shortened views) it wasn't as easy to 'see' how bad it was, compared to being in a spot with a view across the bay, for example.

Those views, or lack of, really highlight the amount of smoke.

Excuse me while I get back to sweeping the forests.

Raking and sweeping, let's get started!!
