Mildew-Resistant Pleated Panel Air Filters

A compound inhibits mildew and mold growth. These filters have pleats that create a large surface area for filtering without reducing airflow, and they have a tacky surface to retain particles.

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

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.
