It is important for people with allergic asthma to clean and dust their homes regularly. Use of a face mask or a double-bagged vacuum with a high-efficiency particulate air filter is recommended.
Typically, improvements in allergic asthma symptoms happen quickly after avoidance of the allergen, although the allergen itself (eg, cat dander) may remain in the environment for months after chief removal of the source. In most cases, a multifaceted approach to environmental control is necessary.
People with asthma must avoid active smoking and exposure to passive smoke. Room air ionizers have not been shown to be effective for people with chronic asthma. Moreover, generation of ozone by these machines may be harmful to some people.
