In some people, allergies or sensitivity to dust contribute to health problems, especially asthma.
Dust isn t just an accumulation of fine dirt.
It can contain molds, fibers, animal dander, and dead dust mites. Dust mites are microscopic bugs that make their home in fabrics such as bedding, upholstery, and carpets. While they live happily in the warm days of summer they die in the winter. When you see dust particles suspended in that ray of sunshine entering the window, what you are really seeing is dead mites and their waste products. In fact, people who have a dust allergy are actually allergic to dust mite waste.
