Active Comparator: 1 Community Health Worker Intervention
This is the active control group, which all 150 participants will receive. It consists of visits from trained community health workers, who will provide asthma education, as well as provision of equipment and supplies to reduce indoor environmental exposures for asthma. These will include: vacuum cleaners, mattress and pillow covers, cleaning supplies.
Behavioral: Community Health Worker Intervention
The Community Health Worker (CHW) intervention consists of visits by CHWS to help families reduce children's exposure to common asthma triggers (allergens and irritants) in the indoor environment. The content of the CHW visits and the materials distributed will follow NHLBI Expert Panel Report 2 recommendations. Each household will receive 6 visits over a 12-month period in which the CHW will provide education on environmental triggers (e.g., reduction of dust mites, cockroaches, cat and dog dander, and environmental tobacco smoke); materials including vacuum cleaners with HEPA filters, mattress and pillow covers, and cleaning supplies; social support to the caregivers; and, if indicated, referrals to other services.
Other Name: community health workers
Experimental: 2 Air Filter
The 50 families in the Air Filter Arm will receive an air filter in addition to the standard community health worker intervention. The Air Filter will be installed right after baseline measurements in the home.
Other: Air Filter
Fifty households will receive an Air Filter, in addition to receiving the standard community health worker intervention. These households will receive a HEPA room AF (Whirlpool 510 or equivalent), a relatively high capacity unit that can be quietly operated. Similar to other studies the filter will be placed in the room where the child sleeps. The HEPA AF will be installed at the beginning of the intervention period.
Experimental: 3 Air Filter and Air Conditioner
Fifty families will be assigned to the "Air Filter and Air Conditioner" Arm. In addition to the standard community health worker intervention, they will receive an air filter and an air conditioner (for the warmer months).
Other: Air Filter and Air Conditioner
Fifty households will receive the air filter and the air conditioner, in addition to receiving the standard community health worker intervention. The air filter will be installed at the beginning of the intervention, after baseline measurement. In the spring of the year (2009), a small window AC unit (Whirlpool Designer Style ACQ058MM or equivalent) will also be installed in the room where the child sleeps.

- Reduced Particulate Matter (PM) in the home of the children with asthma [ Time Frame: End of one year intervention ]
