Air pollution generated from wildfires is significant and can well exceed the total industrial and mobile source emissions in the San Joaquin Valley, overwhelming all control measures and resulting in periods of poor air quality that can cause significant impacts to public health. In a well-sealed indoor environment (e.g., windows and doors closed and sealed tightly), High Efficiency Particulate Air (HEPA) filtration devices can reduce particulate matter indoors by more than 90 percent. The District encourages the use of air filtration devices during wildfires events. The use of air filtration devices to create “clean air rooms”, such as a bedroom, will ensure that the home has a dedicated space with safe indoor air quality during smoke events.
To help mitigate the harmful health effects of wildfire smoke on Valley residents, and in particular the District’s most vulnerable populations, the District has developed the Clean Air Rooms Program to provide residential air filtration units FREE to Valley residents in disadvantaged communities.
If you are ineligible for the Clean Air Rooms Program, the District encourages you to purchase your own home air purifier or make your own.
The District also encourages you to create a clean air room inside your home during poor air quality attributed to wildfire smoke.
