Yes, it is advisable to turn off your air exchanger when there is a nearby wildfire. Air exchangers, also known as ventilation systems, draw in outdoor air and circulate it throughout your home. During a wildfire, the air quality outdoors can deteriorate due to smoke, ash, and pollutants released into the air. By turning off your air exchanger, you can prevent these contaminants from entering your home and potentially compromising indoor air quality.
Closing windows and doors can further help minimize the infiltration of smoke and pollutants. If you have a high-efficiency HVAC system, it might have air filtration features that can assist in reducing indoor air pollution. Once the wildfire threat has subsided and air quality improves, you can resume using your air exchanger and ventilation system.
Remember, the safety of your indoor environment is paramount during a wildfire, and taking precautions to minimize exposure to outdoor pollutants is essential for the well-being of you and your family.
