Do-it-yourself air filters are safe, effective and can be used to protect your lungs from California wildfire smoke.
Wildfire smoke is harmful and can stretch hundreds of miles. The smoke from the 2021 Dixie Fire in California was felt as far as Denver, The New York Times reported. Here are two safe options, according to the University of California, Davis, the U.S. Environmental Protection Agency and the California Air Resources Board.
WHEN SHOULD I USE AN AIR FILTER?
Good air filters can remove dangerous smoke particles from your home. According to the California Air Resources Board, indoor air cleaners help filter out small particulate matter that can cause health concerns.
Wildfire smoke produces harmful air pollutants that can aggravate existing health problems and increase the risk of heart attack or stroke.
The resource board recommends using a certified air cleaner whenever the air quality index is at an unhealthy level, which you can check at AirNow.gov. The agency also says if a board-certified commercial system is not an option for your home, a DIY is an OK alternative.
“These temporary air cleaners should be used with extreme caution, and only if other air cleaning options are unavailable,” the board writes on its website. It says never leave the device unattended and only use box fans manufactured in the last 10 years (after 2012), as those fans “will have a fused plug, which will prevent electrical fires if the device is knocked over.”
