I can provide some general information about window air conditioners that might be helpful.
Most window air conditioners are designed to recirculate the air within the room they are installed in, rather than pulling in outside air. The primary purpose of an air conditioner is to cool the indoor air by removing heat and humidity from the room, not to bring in fresh air from the outside. These units typically have a closed-loop system where the cooled air stays inside the room, and the hot air is expelled outside through the unit's exhaust or condenser.
To verify if your Frigidaire window AC pulls in outside air or not, it's best to refer to the product's user manual or contact Frigidaire customer support directly. The user manual should provide information about the unit's airflow and ventilation system, including whether it uses outside air or operates in a recirculation mode.
If you are concerned about smoke or other outdoor pollutants entering your home, you can use the window AC in combination with an air purifier to help improve indoor air quality. Air purifiers are designed to filter and clean the air, removing particles such as smoke, dust, and allergens, which can be particularly beneficial if you live in an area with poor air quality.
Again, for specific information about your Frigidaire window AC model, consult the product's user manual or reach out to Frigidaire's customer support. They will be able to provide accurate and detailed information regarding your unit's ventilation and airflow system.
