All my cleaning efforts (vacuuming, washing bedsheets, washing moldy shower
curtain, cleaning kitchen) are paying off: the air is cleaner, and I breathe
more easily at home.

My work area is still like a sea of cubicles in a smoke chamber. While the
air has become cleaner outdoors, the smoke, ash, and soot seems to be
trapped inside the building. Perhaps it is because they haven't cleaned all
the HVAC ducts. Perhaps they have not vacuumed the entire area thoroughly.
Anyway, I still need a protective mask to be able to breathe the air inside
my cubicle chamber. I'm thinking about taking my air cleaner to work too.

It is impossible to be in a good mood when one is not feeling well
physically.
