The inner or secondary filter acts as an optionally available filtration during servicing of the primary filter. It generally fits inside the outer element. It can also protect the air from airborne particles if the main filter is damaged or replaced.
Designed for high performance under both normal and difficult operating conditions, Minipleated Secondary Filters are appropriate for general HVAC and applications operating with variable air volume, turbulent airflow, and high humidity. The combination of durable construction and high efficiency also makes it ideal for specialized systems such as diffusion filters in paint booths and prefilters in cleanrooms.
