Asthma is a multifactorial disease that develops from various risk factors, many of them environmental. Indoor environments are by far the most influential. Dust, pests, rodents, mold, pet dander and tobacco smoke are all asthma triggers. a.i.r. nyc works with families to reduce these triggers and develop best practices in the home for asthma self-management. Referrals to smoking cessation programs are also part of the a.i.r. nyc model, as well as pro bono legal assistance for major environmental problems involving landlords. 

Outdoor air is also a factor. Pollen, pollution, and other particulate matter can cause an asthmatic episode. Routine use of asthma control medications can help to reduce exacerbations.
