How Bad Was Air Quality This Summer?

I have sleep apnea and use a CPAP machine.

In addition to the regular filters, I have a super-duper one, which starts out white.

Here’s what it looked like when I changed it this fall:

CPAP machine filter after a summer of Canadian forest fire smoke.
Smoke on June 28, 2023, during a trip to Wisconsin for cheaper gasoline.
Smoke June 28, 2023, on an trip north on Route 31 from Crystal Lake.

At least at night I didn’t breathe the smoke polluting our part of North America.

  1. I am glad your CPAP filter kept at least some of the smoke & dust out of your lungs, Mr. Skinner.

    Your photo shows a filter that could definitely use a change.
