Residents across the western United States are being urged to stay indoors due to thick wildfire smoke blanketing the region. Air quality in several regions of California, Oregon, and Washington are listed as “unhealthy” or “very unhealthy,” according to AirNow, a partnership of the U.S. Environmental Protection Agency, National Oceanic and Atmospheric Administration (NOAA), National Park Service, NASA, Centers for Disease Control and Prevention (CDC), and tribal, state, and local air quality agencies.
Why is wildfire smoke so bad for you?
Wildfire smoke can cause your eyes to burn, irritate your respiratory system, worsen chronic heart and lung diseases, and make you more prone to lung infections, including COVID-19, according to the CDC. Smoke is made up of a mixture of gases and fine particles that are created when wood and other organic materials burn, the Environmental Protection Agency (EPA) explains. But the microscopic particles in smoke are the most concerning—they can travel deep into your lungs. That can cause a range of health problems, ranging from airway issues to premature death.
Can an air purifier reduce exposure to wildfire smoke?
Staying indoors when your region has poor air quality due to wildfire smoke is important, but fine particles in the air can still make their way into your home, says Raymond Casciari, M.D., a pulmonologist at St. Joseph Hospital in Orange, Calif. “They can absolutely impact indoor air quality,” he says.
That’s why running an air purifier or air filter can be helpful, says Jonathan Parsons, M.D., a pulmonologist at The Ohio State Wexner Medical Center. “Air purifiers draw in polluted air, trap the particles, then blow out clean air.” Portable air cleaners with high efficiency filters can reduce indoor particle concentrations by as much as 85%, according to the EPA.
That said, they won’t be “universally protective” in areas where high levels of smoke are an issue, Dr. Parsons says.
How to choose an air purifier for wildfire smoke
When looking for an air purifier, the EPA recommends checking the square footage rating of the device to be sure it can clean the space you need it for. It’s also important to look for a high-efficiency or HEPA filter. While they may be more expensive, they are more effective than other filters.
Also keep this in mind, per the EPA: “Air cleaners that cost less than about $200 often do not clean the air as well and may not be helpful for wildfire smoke.”
Finally, if you decide to invest in an air filter, Dr. Casciari says it’s important to use it properly. “In order for them to be really effective, you need to close off the room and run them 24/7,” he explains.
