What is typically a consideration when selecting HVAC filters?

When selecting HVAC filters, one of the primary considerations is airflow resistance. This factor is crucial because it determines how easily air can pass through the filter. Filters with high airflow resistance can impede the HVAC system's efficiency, leading to increased energy consumption and reduced overall performance. An optimal filter should balance effective air cleaning with low resistance to maintain airflow and system efficiency.

While other factors like filter size and material sustainability are important for ensuring compatibility and environmental considerations, respectively, airflow resistance directly impacts the system's operational efficiency and airflow. Thus, choosing a filter with the appropriate airflow resistance is essential for maintaining the performance and longevity of HVAC systems.
