can furnace run without filter

 

Yes, a furnace can technically run without a filter, but it is not recommended. The filter in a furnace serves an important purpose by trapping dust, debris, and other particles that would otherwise circulate through the air in your home. Without a filter, these particles can accumulate in the furnace’s blower and other components, potentially causing damage or reducing the system’s efficiency. Additionally, the lack of a filter can lead to poor indoor air quality, which can have negative health effects, particularly for those with allergies or respiratory problems. Therefore, it is important to regularly replace or clean your furnace filter to ensure proper operation and maintain good indoor air quality.
