Wildfires have long been a part of the warm-weather months around the globe, but extreme heat and a worsening drought across much of North America is making 2021 a dangerous year for wildfires. Smoke from wildfires consists of harmful gases and fine particles that can travel thousands of miles and impact the air you breathe right in your backyard, even if it doesn’t feel like you live in a fire zone. This can compromise the air quality in your area so severely that officials will alert people that it is not safe to go outside or to limit your exposure to outdoor air.

Wildfire smoke can be especially harmful to the elderly, pregnant women, children and those with chronic heart and lung diseases. Because children breathe more air per pound of body weight than adults and their airways are still developing, they may experience more severe symptoms. To avoid the impacts such as difficulty breathing, eye irritation, headaches, sinus infections and many more harmful effects, the following are a few recommendations to protect yourself and your family when there are active fires near your home, but you are not in immediate danger. If there is an active fire near your house, follow guidelines from your local authorities to determine if you are safest to evacuate.


Air Quality Index Guide

Air agencies across the U.S. use the Air Quality Index (AQI) to communicate about air quality. The AQI is a nationally uniform color-coded index developed by EPA for reporting and forecasting daily air quality. AirNow provides air quality reports down to the zip code to help you make decisions accordingly. Check to track your air quality or sign up for local alerts for health warnings including poor air quality, PSAs, and info for when you are at high fire risk or active fire. 

If you see that it looks smoky outside, avoid strenuous activities, and wear a mask or stay indoors to wait until air quality improves. Smoke levels can vary a lot during the day, so be selective when you choose to open windows or do errands.

Most people need to leave their home even in poor air quality situations like wildfire smoke. When doing so, the easiest way to protect yourself is with a mask that provides the equivalent of N95 protection. The RZ® Mask M2 Mesh is a good option with the easy on and off neck strap so you can throw it on as needed for long or short excursions. Be sure that you fit your mask properly, with a tight seal as that is the only way to achieve 99.9% protection from the smoke and airborne particulates. Keep a mask in your bag, car, and home for use as needed.

Close all vents, doors, windows, garage doors and pet doors to prevent as many smoke particulates as possible from entering your home. If you live close to a wildfire but are not evacuating, designate a “clean room” with as few windows as possible. Stock up on essentials like groceries and medication so you don’t need to go outside when it’s smokey.

Reduce all sources of indoor air pollutants and activities that create more pollutants such as frying foods, sweeping, vacuuming, and using gas-powered appliances, propane or wood-burning stoves, and smoking.

 Limit use of appliances during heavy smoke events.


Portable air cleaners, also knowns as air purifiers, help filter the air in a single room vs. a central furnace or HVAC filter which is designed to filter the air in your home. Air purifiers help reduce airborne particle levels to improve indoor air quality. According to New York Times/Wirecutter guide to air purifiers, wildfire smoke predominantly consists of fine particles in the 0.4 to 0.7 micron range. The best air purifiers for wildfire smoke use a high-efficiency particulate air (HEPA) filter to trap fine particulate matter of this size. They recommend running the purifier on high the first time you use it to clear the room, and thereafter running them on low continuously to keep your air clear. If you have an HVAC system with a fresh air intake, set the system to recirculate mode, or close the outdoor intake damper. If you use a window air conditioner where the damper cannot be closed, do not use it during high smoke periods.

Most people with limited exposure to smoke will not have extreme or longterm health effects. However, if you suffer from allergies or other health sensitivities, these steps will help limit side effects.
