About Air Filter Efficiency Ratings

These filters are typically used as replacements in HVAC equipment.

All meet UL Classified flame retardance requirements. Actual size is up to 5/8” more or less than trade size.

Prefilters can be used as a standalone filter or a prefilter that guards your main filter. They’re an economical choice for protecting expensive filters that catch fine particles.

Made-to-Order Panel Air Filters

Minimum filter size is 4" × 4". Maximum filter size is 23" × 30". Multiply the length × width to determine square inches. Then, see size ranges for pricing.

Typically used as replacements in HVAC equipment, these filters work as a standalone filter or a prefilter that guards your main filter. They’re an economical choice for protecting expensive filters that catch fine particles.

All meet UL Classified flame retardance requirements.

Also Available: Filters larger than 23" × 30". Please ask for 3884T999 and specify material, thickness, actual length, and actual width.

Reusable Air Filter Rolls

Wash and reuse these rolls. Cut to the size you need.

These rolls meet UL 900 flame retardance requirements.

Polyester pads require no frame--rigid polyester is firm enough to be used without one.
