It isn’t the first year that Canadian wildfires have impacted areas of the United States, with billowing waves of wildfire smoke causing record high ratings of poor air quality and unhealthy conditions. 2023 was one of the worst wildfire seasons in Canada when over 42 million acres burned, turning the New York skyline orange and worsening air quality in areas like Detroit and Washington DC.

With wildfire smoking spreading as far south as the Gulf Coast states, air quality and visibility will be impacted, especially for those at risk like young children and the elderly.

The wildfire season is occurring earlier and lasting longer due to warmer springs, longer summer dry seasons, drier soil and climate change, according to the EPA. The alarming rise in wildfire activity over the past decade has transformed what was once a regional concern into a nationwide health crisis.

As wildfire events become more frequent and intense, having the right protective equipment is essential. From properly fitted N95 respirators to air purification systems, investing in a few key products can help safeguard your respiratory health during what experts predict could be another challenging wildfire season ahead.

Fire weather relies largely on three main meteorological conditions to spread wildfires: relative humidity, temperature and wind. We’ve discussed relative humidity (RH) in our Dehumidifier Guide, which is expressed as a percentage and represents the amount of water vapor in the air at a given temperature. When relative humidity is low, the air pulls moisture from the land and vegetation.

Hotter temperatures will also fuel fire weather, with warmer nighttime temperatures decreasing overnight relative humidity. As for the wind, how can a fire burn without oxygen? Wind also increases evaporation and land dryness, and may carry embers that can rapidly spread fires.

Over 50 million Americans suffer from seasonal allergies, including hay fever, food and skin allergies, and allergic asthma, while over 28 million have asthma, a chronic disease that causes inflammation and swelling in the airways, trouble breathing, coughing and pain.

For those with respiratory sensitivities, the fine particulate matter in wildfire smoke presents a serious health threat, and it doesn’t only come from fires in your area – wildfire air pollution can extend hundreds of miles beyond the flames themselves.

Wildfire smoke is a mix of gasses and fine particulate matter from burning vegetation and other materials. These microscopic particles, measuring 10 microns or smaller (known as PM10) can be inhaled into the lungs, and fine particulate matter that are 2.5 microns or less (known as PM2.5, smaller than the average human hair), can penetrate deep into the lungs and even enter the bloodstream, triggering lung inflammation and potentially leading to long-term health complications. When combined with seasonal pollen—which climate change has also intensified through longer growing seasons—these environmental pollutants create a perfect storm for respiratory distress.

Short-term risks to wildfire exposure may cause coughing, wheezing, difficulty breathing, bronchitis, increased risk of asthma and other respiratory distress. If exposed over days or weeks, you may even see reduced lung function.

According to the CDC, there are a few precautions you can take for proper protection against wildfire smoke.

If you must brave the outdoors during a wildfire event, a proper safety mask should be worn to help prevent lung irritation. Even staying indoors may not be a sure thing, as a certain amount of home “leakiness” will occur during wildfire and allergy seasons due to opening doors or using portable air conditioners that pull in air from outside. Here’s a few products to help protect yourself during wildfire season.

As you shop for mask options, note that KN95 masks are not the same as a N95 mask. N95 masks are generally the most effective protection against airborne particles (and ideal for healthcare and industrial workers), but they are uncomfortable and require a tight fit.

KN95 masks, however, may allow a certain amount of leakage and will have a different kind of certification. Both still require several layers of synthetic material for particulate protection.
