Replacing Gas Stoves With Portable Electric Appliances to Improve Indoor Air Quality and Asthma Control

The goals of this study are to determine if replacing gas stoves with portable electric hot plates and electric toaster ovens will improve indoor air quality and asthma control. Researchers will enroll participants with poorly controlled asthma and provide them with hot plates and toaster ovens to use instead of gas stoves. Researchers will measure indoor air quality about 1-2 weeks before and about 2-3 months after providing portable appliances. Participants will answer questions about their asthma symptoms and take lung function tests about 1-2 weeks before and about 2-3 months after using portable appliances.
