Wildfires lead to widespread damage and billions of dollars in suppression costs yearly. Per the National Interagency Fire Center, over $4 billion was spent suppressing wildfires in 2021, roughly twice as much as the previous year. Aside from property damage and the inherent dangers associated with large-scale fires, these events can also lead to a dramatic drop in air quality. Poor air quality can lead to cardiovascular and respiratory issues and may even impact your mental health. If you live near an area prone to wildfires, you must understand which devices can help you clear your home of wildfire smoke.

How do wildfires impact air quality?

Various factors, including volatile organic compounds, ozone, noxious gases and particulate matter worsen air quality. Particulate matter is the primary offender in wildfire smoke, as these events produce tiny particles that can enter your lungs or bloodstream. According to the California Air Resources Board, “health problems related to wildfire smoke exposure can be as mild as eye and respiratory tract irritation and as serious as worsening of heart and lung disease, including asthma, and even premature death.”

The recent wave of Canadian wildfires has led to large plumes of smoke blanketing New York City, resulting in a massive drop in air quality. On Wednesday evening, the air quality in New York City was 484 on the Air Quality Index; anything over 301 is considered hazardous. New York City officials have asked that residents wear N95 masks to protect their health.

What to do if you’re affected by the wildfires

Wildfire smoke tends to enter the home through openings in windows and doors. Try to keep your windows and doors closed as often as possible. Applying weather strips will help keep smoke out of your home. Of course, if there is an active air quality issue in your area, try to limit the time spent outside applying these strips and ensure you wear a mask. It’s important to note that heat can pose a serious health risk if there is a nearby wildfire, so you may have to open a window temporarily to cool your home. Alternatively, you can run your air conditioner on its recirculating setting to cool your house down without drawing in air from outside.

Consider replacing your home’s HVAC filter with a high-efficiency filter for particulate matter. Per the Environmental Protection Agency, anything with a MERV rating of 13 or higher can capture up to 50% of particles between 0.3 and 10 microns.

If you have pets, you may want to consider setting up an area in your house for them to use the bathroom. Although this can enforce bad habits, it will help keep them safe. If you do take them outside to use the bathroom, try to limit the amount of time you spend in the smoke and wear an N95 mask. It’s essential that you put the mask over your mouth and nose and don’t leave room for the smoke to enter your lungs.

Air purifiers are a must-have for those living in areas prone to wildfires. These devices clean the air in your home and can remove some of the particulate matter from your indoor environment. Consider an air purifier with a HEPA filter, as these generally remove more particles from the air than a traditional model. If you have a large home, you may want to buy multiple units, as they have a limited range.

It’s also a good idea to place a few air quality monitors around your home. These devices let you know when the air in a particular room is unsafe to breathe. These can be an excellent way to identify the safest room in your home while knowing where your air purifier is needed most.
