What You'll Learn
Stay indoors with windows and doors closed
When air quality is poor due to smoke-filled pollution, it is recommended to stay indoors with windows and doors closed. This is because outdoor pollutants can easily find their way inside and worsen the indoor air quality. Even with closed windows and doors, indoor air can be polluted by outdoor sources, so it is important to take measures to limit this.
Firstly, it is important to keep indoor air as clean as possible. Avoid activities that increase indoor pollution, such as burning candles, incense, or using gas stoves. If you have an air conditioning system, set it to "on" so that air is being filtered constantly. If your system brings in fresh air from outside, close the fresh-air intake so that it operates in recirculation mode. Install a high-efficiency filter (MERV 13 rating or higher) with a MERV rating as high as your system can handle, based on manufacturer recommendations. Alternatively, consider using a CARB-certified air cleaner to reduce indoor particle levels.
If you do not have access to air conditioning, the Washington State Department of Health recommends closing your curtains and blinds and turning on a fan. If possible, you could also consider going to a family member's or friend's house with air conditioning.
It is also important to be aware of the risks of being outdoors during smoky conditions. Exposure to smoke can have a range of health effects, from eye and respiratory tract irritation to worsening heart and lung disease. If you must be outdoors, consider wearing a NIOSH-certified N95 respirator mask to reduce your exposure to smoke.

Avoid exercising outdoors
When air quality is impacted by smoke, it is important to consider whether it is safe to exercise outdoors. Smoke from wildfires can contain harmful pollutants, including fine particles (PM2.5) that can be detrimental to your health. These particles are often invisible and can infiltrate your lungs, and even enter your bloodstream. As such, it is recommended to avoid exercising outdoors during smoky conditions.
The risks associated with outdoor exercise in smoky conditions depend on several factors, including the duration of exposure, the level of exertion, the current air quality, and your overall health. Individuals with existing respiratory, lung, or heart conditions are particularly vulnerable and should take extra precautions by limiting their time outdoors and consulting their doctor about wearing a respirator mask.
Even for healthy individuals, it is generally advised to refrain from outdoor workouts when the Air Quality Index (AQI) reaches unhealthy levels. This is typically indicated by an AQI of 151 or above in the United States, but sensitive individuals may experience health effects at lower AQI levels. To make informed decisions, it is essential to monitor air quality using reliable sources such as the Air Quality Health Index (AQHI), special air quality statements, or air quality forecasting apps.
If you choose to exercise outdoors during smoky conditions, opt for high-intensity but brief workouts rather than low-intensity, prolonged ones. However, it is crucial to recognize that there is limited research on the health effects of short-term exposure to wildfire smoke during exercise, and the potential risks may vary depending on individual factors.
To maintain your physical activity levels while avoiding outdoor exercise, consider finding alternative indoor spaces with cleaner air, such as a gym or community centre. Prioritize keeping the indoor air as clean as possible by closing windows and using air filters or air purifiers. Additionally, listen to your body and be mindful of any symptoms that may arise, even when exercising indoors.

Wear a respirator mask if you go outside
If you must go outside when there is smoke pollution, it is advisable to wear a respirator mask. Wildfire smoke is a mix of gases, particles, and water vapour, and the main health risk comes from fine particles (PM2.5) that can get deep into the lungs and even pass directly into the bloodstream. These particles are not visible to the human eye, and there is no known safe level of exposure.
Wearing an N95 mask is an effective way to protect yourself from smoke pollution. N95 masks filter out 90-95% of particles, and they were commonly used during the coronavirus pandemic. It is important to ensure that your N95 mask is NIOSH-approved, well-fitting, and has no gaps. If you have a heart or lung condition, consult a doctor before using a respirator mask, as it can make breathing more difficult.
If you are unable to obtain an N95 mask, a dust mask is better protection than a cloth mask. Cloth masks do not provide adequate filtration against smoke particles. It is also important to remember that masks are not a substitute for limiting your time outdoors during smoke pollution. If you start experiencing symptoms like wheezing or shortness of breath, head indoors or to an area with better air quality.
In addition to wearing a respirator mask, you can take other precautions when venturing outside during smoke-filled pollution. Check local air quality advisories and the Air Quality Health Index (AQHI) to assess the risk level in your area. If possible, find indoor alternatives for activities that would usually be done outdoors. If you must be outdoors, avoid strenuous activities that will increase your exposure to polluted air.

Keep indoor air clean
Keeping indoor air clean is of utmost importance during smoke-filled pollution. Here are some ways to do so:
Firstly, staying indoors with windows and doors closed is crucial when outdoor air quality is poor due to smoke. If possible, avoid spending time in areas without proper ventilation or air filtration systems. If you have a central HVAC or air conditioning system, ensure it is set to "on" for constant air filtration rather than "auto," which operates intermittently. Additionally, if your system brings in fresh air, close the fresh-air intake or set it to "'recirculate'" mode to prevent outdoor smoke from entering your home.
It is also important to use high-efficiency filters in your HVAC or air conditioning systems. Look for filters with a MERV 13 rating or higher, based on manufacturer recommendations. Upgrading your filters can significantly reduce indoor particle levels. If your system cannot accommodate a MERV 13 filter, consider using the highest-rated filter it can handle.
Portable or DIY air cleaners can also be effective in improving indoor air quality during smoke events. Commercial air cleaners may be difficult to obtain due to limited availability or high cost. In such cases, instructions and materials for creating your own air cleaner are provided by organizations like the EPA and other nonprofits. These DIY solutions involve attaching an air filter to a box fan with tape, brackets, clamps, or a bungee cord. However, there are concerns about the potential for box fans to overheat when used with a filter, which could pose safety risks.
While plants have been touted for their air-purifying abilities, recent research suggests that even a dense collection of houseplants has a minimal effect on indoor air quality. Instead, focus on taking preventive measures, such as those mentioned above, to ensure indoor air remains as clean as possible during smoke-filled pollution.
