Prefilter Panel Air Filters

These filters are an economical choice for protecting more expensive filters that catch finer particles. They are typically used as replacement prefilters in HVAC equipment.

They meet UL 900 flame retardance requirements. Actual size is up to 5/8" less than trade size.
