My six-year old has chronic allergies. He has been tested and found to be highly allergic to dust mites. I want to buy an air cleaner for his room so that he will sleep better.
Dust mites are creatures that are related to spiders and ticks.
They are commensal with humans, that is, they live where we do. Their main food supply is skin scales that slough off our bodies and accumulate in bedding, upholstery, and carpeting. These excretions are very large and do not remain airborne for more than a few minutes. Exposures which cause sensitization and symptoms result from disturbances such as bed-making, sleep movements, upholstery and carpet cleaning, etc. Because dust mite allergens settle out very quickly it is highly improbable that an air cleaner will provide any clinical benefit.
