During periods of wildfires and smoke, it's generally advisable to keep your windows and doors closed to prevent the entry of smoke into your home. As for your air conditioner, it depends on the type of system you have.
Central Air Conditioning: If you have a central air conditioning system with a properly functioning and well-maintained air filter, it can help filter out some smoke particles. However, it's important to ensure that the filter is clean and in good condition. If you have a high-quality filter such as a HEPA filter, it may be more effective at capturing smoke particles. However, keep in mind that air filters in standard residential air conditioning systems are not specifically designed to remove smoke particles, and their effectiveness can vary.
Window Air Conditioners: Window units generally do not provide effective filtration of smoke particles. If you have a window air conditioner, it's advisable to turn it off during periods of heavy smoke to prevent the entry of outdoor air and smoke into your home.
In both cases, if you have a dedicated air purifier with a HEPA filter, it can be more effective at removing smoke particles from the indoor air. Consider running an air purifier in the rooms where you spend the most time to further improve indoor air quality during wildfire events.
It's important to note that if you're experiencing significant smoke infiltration despite taking these precautions, it might be best to seek shelter in a designated clean-air space or follow any local advisories or evacuation orders issued by authorities.
Ultimately, it's crucial to prioritize your health and safety during wildfire events. Stay informed about air quality conditions in your area and follow the guidance of local authorities and health agencies for the best course of action.
