These disposable air filters are designed to protect furnaces and central air units in residential and light commercial applications. They function without a retainer by adhering the frame directly to the media which has a light skin.
Designed to Last
Their one-piece frames are made from heavy chipboard to eliminate corner separation. The filtering media inside the frames is made from continuous filament spun glass.
Sealing is accomplished with a resinous hot-melt bonding agent. This bond runs the full perimeter of the frame's upstream and downstream sides to provide rigidity and resistance to media compression.
Tested for Quality
These filters have been tested by Underwriters Laboratories Inc. and are classified as UL 900 Class 2 for flammability. Their UL marking appears on the frame. Complementing their UL listing is their MERV 4 rating.
All of these furnace air filters are priced individually. However they're sold in case quantities only.
