Yep --- Here in bucolic Springwater, NY, able to look at the ashen sun directly, and advised to avoid breathing, unless absolutely necessary. That's been every day for several now and also tomorrow (coming up right now). But I (being myself) am still hiking the State Parks every day, regardless --- coughing up phlegm, sneezing, and "gritty" feeling eyes. Today I mowed for 3+ hours and then hiked 3++ miles before sunset. Disrobed on the front porch; straight to the shower to wash and rinse the grit off, and then check my magnificence for deer ticks... only two this time. I then took some pictures of the flowers by the garage and returned to the house, ate like an entitled pig. The air in the house is HEPA filtered. Now I'll lay me down to sleep. Repeat the entire drill tomorrow. Tom
"HEPA is a type of pleated mechanical air filter. It is an acronym for "high efficiency particulate air [filter]" (as officially defined by the U.S. Dept. of Energy). This type of air filter can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm). The diameter specification of 0.3 microns corresponds to the worst case; the most penetrating particle size (MPPS). Particles that are larger or smaller are trapped with even higher efficiency. Using the worst case particle size results in the worst case efficiency rating (i.e. 99.97% or better for all particle sizes)."
