I will be conducting an asthma study this summer in the Colonial Heights area.  This will regard middle school aged children.  I am going to go to their homes and survey the air quality factors that I believe may relate/worsen their asthma and breathing habits.  Some factors are but are not limited to

How often the air filter is changed?

Do people smoke in the home?

Are pillow covers used? What about mattress condition/materials?

Indoor Pets?

Overall cleanliness of home... i.e. dust?
