Photographers at a wildland fire may be able to use and tolerate a mask that traps 95 percent of the 0.3 micron particulates in smoke, but the devices are not practical for firefighters. (see photo above)
In case you are wondering, masks and respirators are divided into rating classes: N is not oil resistant, R is oil resistant, and P is oil proof. The number, such as 95, refers to the percent of particles removed that are at least 0.3 microns in diameter.
Be careful out there.

Wildfire Smoke Update
Areas of haze from wildfire smoke to our west will increase a bit tomorrow, especially later in the day. Note, this will be less dense than the smoke we saw this morning. Periods of haze will remain possible into the upcoming week. #utwx pic.twitter.com/TMLroL297p
