In a study by Wood , excluding cats from the bed room and using HEPA filters had been found to be efficient in reducing cat allergen levels; however, there was no reported improvement in asthma or allergic rhinitis symptoms. Van der Heide , carried out a -month HEPA filter intervention research in pet-sensitized kids with bronchial asthma and demonstrated important reductions in bronchial hyperresponsiveness but no differences in symptom scores or treatment use in pet-sensitive asthmatic children. These outcomes were not replicated in an identical research. Reisman found reductions in bronchial asthma/rhinitis symptoms during energetic HEPA filter use. Macintosh , additionally found WHF to be efficient in eradicating fantastic particles from indoor air. Lanphear , carried out a double-blind randomized control trial of asthmatic children with identified second-hand tobacco smoke exposure. The intervention group obtained HEPA filters and the control group received sham air filters. It was demonstrated a reduction of airborne nicotine particles and in the number of unscheduled asthma visits in a -month follow up interval within the intervention group.
