About Air Filter Efficiency Ratings

The pleats create a large surface area for filtering without reducing airflow. These filters are typically used as replacement filters in HVAC equipment. The cardboard frame is treated to resist humidity, and the galvanized steel grill prevents sagging.

These filters meet UL 900 flame retardance requirements. Actual size is up to 5/8” less than trade size.

Panel Air Filters

These filters are typically used as replacements in HVAC equipment.

All meet UL Classified flame retardance requirements. Actual size is up to 5/8” 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.

Mildew-Resistant Snug-Fit Panel Air Filters

A compound inhibits mildew, mold, and fungi growth on these filters. The filter material extends beyond the frame for a tight fit, creating a seal to prevent air from bypassing the filter around its edges. A tacky surface on the filter retains particles.

These filters meet UL 900 flame retardance requirements. Actual size is 3/4" greater than trade size.
