Impact On Indoor Air Quality
Deciding whether to set your AC fan to “Auto” or “On” can affect indoor air quality. This choice influences how pollutants and humidity are managed in your home.
Pollutant Filtration
The AC fan setting impacts how well the system filters pollutants. In “Auto” mode, the fan runs only when cooling or heating. This means the air gets filtered less often.
In “On” mode, the fan runs continuously. This helps filter air more frequently. More frequent filtration can reduce dust, pet dander, and pollen. Cleaner air can improve your family’s health.
Humidity Control
Humidity levels are crucial for indoor air quality. In “Auto” mode, the fan stops when the AC cycle ends. This helps to remove more moisture from the air.
In “On” mode, the fan runs without stopping. This can lead to increased humidity. Continuous airflow can re-evaporate moisture, making the air more humid.
Fan Setting | Pollutant Filtration | Humidity Control |
---|---|---|
Auto | Filters air less often | Better humidity removal |
On | Filters air more often | Can increase humidity |
Choosing the right setting depends on your needs. If you want cleaner air, use the “On” setting. For better humidity control, use the “Auto” setting.
