This study aims to establish whether air filtration units used in homes with pets cause a dramatic fall in airborne pet allergen levels, and if so, what effect this has on human and animal health.
Background Domestic air filtration units have previously been shown to cause a dramatic fall in airborne pet allergen levels in homes with pets. Clinical trials of air filtration units, however, have failed to reveal a significant beneficial effect. Personal pet allergen exposure during air filtration unit use has never been measured.
