(Healthline) – Fires have led to extreme levels of air pollution across California. Experts say those little masks provide some benefits if you use the right one.

Wildfires have erupted across California in recent weeks burning tens of thousands of acres in both the northern and southern parts of the state. The intense fires have stymied fire fighting efforts as they’ve burned through homes and businesses.
And the danger isn’t limited to the immediate surroundings. The fires are also producing enormous smoke plumes which are drifting miles beyond the flames.
As a result, many people — even those dozens of miles away from flames — are at risk for asthma attacks, respiratory distress, and cardiac events due to the increased air pollution.
Across California, the smoke and haze has led some residents to wear masks to protect themselves from the smoke.
How to protect yourself
Dr. Robert Blount, assistant professor of pulmonary pediatric and adult medicine at the University of California San Francisco, told Healthline in an earlier interview that if people can smell or see smoke, they should take steps to protect themselves.
“If there’s enough smoke that you can see it or smell it… then it’s a dangerous level,” he told Healthline.
For extra protection, special face masks called respirators can help.
These masks can provide protection from the small microscopic particles in smoke that can damage the lungs.
Children, the elderly, and people with lung or cardiac conditions are at the highest risk of developing symptoms, Blount explained.
“People need to be pretty careful about heavy smoke exposure,” he said.
Dr. Naveena Bobba, the director of public health emergency preparedness and response at the Department of Public Health in San Francisco, said in an earlier interview that if people start to have symptoms related to the smoke they should stay inside and seek out buildings with filtered air.
“They should also go indoors to a place that has a good HVAC system,” Bobba told Healthline.
If smoke or haze makes its way indoors, Bobba advises running an air conditioner to try and keep out the worst of the pollution. She also said air filters can help clean out the air if a person doesn’t have an air conditioner.
