Mildew-Resistant Snug-Fit Panel Air Filters


Single Panel	Multi-Panel

Limit fungal growth and air leaks. An antimicrobial compound stops mildew and mold from growing on your filter. The filter material wraps around the frame to stop dirty air from leaking around the edges.

Multi-Panel—Also known as link filters. These filters are made of two or more connected panels that slide into one track without gaps. Instead of pushing several single-panel filters into a wide opening, just slide in one of these. They are easy to install in large air handling units, such as those in hospitals, schools, and commercial buildings. When folded, they function as layered filters.

Snug-Fit Panel Air Filters
