No, you’re not imagining it. If you live on the East Coast, you’ve probably noticed the smoke in your area or have received an air quality alert. Wildfires in Canada have created dismal air quality conditions for several states from New England and as far south as Atlanta. While the smoke is expected to clear over the next few days on the East Coast, it may be uncomfortable to be outside in the meantime, particularly if an individual has a pre-existing condition such as asthma.
If wildfire smoke reaches your area, you may be wondering what your options are when it comes to protecting yourself. Here’s what you need to know about wearing masks during wildfire season and what else you can do to protect yourself when exposed to smoke and smog.

What are wildfire smoke and smog?
Wildfire smoke is a mixture of gases and fine particles which contain several toxic air pollutants such as benzene and formaldehyde, that are released when wood and other organic materials burn, according to the EPA.
Filippelli says the microscopic fine particulate matter, specifically, is the “most dangerous” component of the smoke. “When you see a lot of air quality warnings, a lot of that is based on how much of that particle matter is in the air.” These particles can work their way into your eyes and respiratory system which can lead to irritation like burning eyes and illnesses like bronchitis. The particles are especially irritating for those who have asthma or people who are at risk of heart attacks or heart failure.
Smog is described by the EPA as “a mixture of pollutants made up mostly of ground-level ozone” such as transportation emissions. Ground-level ozone is linked to health problems like diminished lung function and emergency visits for asthma, according to the CDC.
Can disposable face masks or cloth masks provide protection?
Albert Presto, research professor for the Department of Mechanical Engineering at Carnegie Mellon University and a member of the Center for Atmospheric Particle Studies (CAPS), explains that the cloth or disposable face masks that you already own may help to block some particulate matter, but it’s most likely not enough to rely on as protection for your lungs. As far as blocking out ground-level ozone found in smog, masks aren’t much help there, says Presto.
For wildfire smoke protection, Presto says you can think of masks as a “ranked order.” Some masks outperform others in terms of efficacy, which may be comparable in the use against particulate matter. As far as masks to avoid completely, the EPA states that you should not rely on dust masks or bandanas as protection against smoke. Similarly, Presto says neck gaiters also offer no protection in this situation.
N95 respirators and KN95 masks are the best options as far as masks go in protecting yourself from inhaling any particulate matter from wildfire smoke.

How to protect yourself from wildfire smoke while outdoors
It’s important to note that the best protection from unhealthy air quality levels is reducing the amount of time spent outdoors if possible. The EPA recommends avoiding strenuous activity outdoors, such as mowing the lawn or going for a run, if the air quality is poor.
In the event that the air quality is so poor that local health officials recommend staying inside, it’ll be useful to have a supply of food, water and other essentials at home. The EPA recommends stocking up on emergency supplies like canned food, medications, and bottled water. An at-home tool that can help mitigate smoky conditions inside your home is an air cleaner, also known as an air purifier. Air purifiers can significantly reduce exposure to harmful particles found in wildfire smoke inside your home. In addition, they offer some protection from VOCs, allergens and more.
If you have to go outside for some reason, the EPA recommends donning an N95 respirator if you have one. These respirators are also great to have if you encounter other emergency situations, such as cleaning up a flood in your home, when you’ll want to avoid inhaling contaminants.
Make sure you monitor your area’s air quality index (AQI) to understand the pollution level and potential health hazards that may accompany it. Sign up for public health alerts or warnings in your area so you can stay in the know about any air quality changes.
