How do temperature changes affect air filter performance?

Temperature changes can significantly influence the properties of filter media, which in turn affects their efficiency in capturing airborne particles. As the temperature fluctuates, the physical characteristics of the filter materials—such as their rigidity, porosity, and surface tension—can change. For instance, higher temperatures may cause some filter materials to become more pliable or less effective at trapping certain sizes of particles, while lower temperatures could make them stiffer or brittle. This alteration in material properties can lead to variations in the air filter's performance, including both its filtration efficiency and its lifespan.

Additionally, temperature can impact the humidity levels within the airflow, which can cause changes in the behavior of dust and other contaminants. Filters may respond differently to moisture based on their material composition, further influencing overall efficiency. Thus, understanding how temperature affects these physical properties is crucial for maintaining optimal air quality and filtration effectiveness in various environments.
