MervPlus™ Pleated Filters

This high quality Merv 11 pleated filter is made of a polypropylene filter material and framed in a rigid glossy cardboard frame.

The filter material incorporates a metallic mesh that permits the filter to fold into an aerodynamic accordion shape. The frame is made of waterproof cardboard.

The MervPlus is an excellent choice for replacing low performance fibreglass or polyester furnace filters.
