Efforts should focus on the home, where 30-60% of time is spent. Patients should clean and dust their homes regularly. [75] If a patient cannot avoid vacuuming, he or she should use a face mask or a double-bagged vacuum with a high-efficiency particulate air filter. If possible, consideration can be given to moving to a higher floor in the house (less dust and mold) or different neighborhood (fewer cockroaches). Active smoking and exposure to passive smoke must be avoided. Room air ionizers have not been proven to be effective for people with chronic asthma, and the generation of ozone by these machines may be harmful to some. Specific factors related to the home include dust mites, animals, cockroaches, mold, and pollen (see Indoor Aeroallergens for more details).
