smaller. Breathable air particles can include pet
dander, bacteria, mold, chemicals from cleaning
products, building materials, fuel-burning equipment
such as furnaces, upholstered goods, cooking,
sweeping, copy machines, skin flakes, clothing fibers,
combustion, cooking, smoke, dust, dirt, spores, and
pollen. Sources vary seasonally.
