Should You Run Your Air Conditioner When It's Smoky Outside?


As wildfires continue to impact air quality across the country, many people are wondering whether it is safe to run their air conditioners during smoky conditions. According to experts, running your air conditioner can be beneficial in maintaining indoor air quality, provided that certain precautions are taken to ensure that the system is functioning effectively.


Air conditioning units work by circulating and cooling the air inside your home, which can help to reduce the temperature and provide relief from smoky outdoor conditions. However, it is essential to follow some guidelines to prevent the introduction of harmful particles and maintain a healthy indoor environment.


  1. Check your air filters: Regularly inspect and replace your air conditioning filters to ensure that they are clean and functioning efficiently. Dirty or clogged filters can reduce the effectiveness of your air conditioner and allow pollutants to enter your home.

  2. Use high-efficiency filters: Experts recommend using high-efficiency particulate air (HEPA) filters, which are designed to capture fine particles such as smoke and dust. These filters can help to improve indoor air quality by removing harmful pollutants from the air.

  3. Keep windows and doors closed: To prevent the infiltration of outdoor pollutants, keep windows and doors closed while running your air conditioner. This will help to maintain a barrier between the indoor and outdoor environments and reduce the amount of smoke entering your home.

  4. Consider using an air purifier: Air purifiers equipped with HEPA filters can further improve indoor air quality by capturing and removing airborne particles. Running an air purifier in conjunction with your air conditioner can provide additional protection against smoke and other pollutants.

  5. Monitor air quality: Stay informed about local air quality conditions and adjust your air conditioning usage accordingly. If the air quality is particularly poor, consider limiting your use of the air conditioner and staying indoors as much as possible.

By following these guidelines, you can safely run your air conditioner during smoky conditions and help to maintain a healthy indoor environment. Remember to consult with local health officials and experts for specific advice tailored to your region and personal circumstances.
