Fiberglass air filters are not designed to last very long and therefore are not very sturdy. They do however often come with which help provide them with a bit more rigidity.
Although pleated air filters tend to be more expensive than fiberglass air filters, the total cost difference when the filter’s usable life cycle is factored in is often negligible (most pleated air filters only need to be changed every 90 days).
Here we see that even though the pleated air filter costs more than double the purchase price of the fiberglass air filter, the total cost of usage over one year is less, plus the user gets to enjoy the added benefits of additional protection provided by the pleated air filter.
Disposable fiberglass air filters are simple filters made for home furnace filtration. These filters are formed from a layer of fiberglass bonded between two metal grids. The metal grids provide rigidity to the filter. The filter is encased in either a cardboard or chipboard frame.

Air Filter Media
Koch Supergrade Fiberglass Air Filter Media is available in a wide range of pad and roll sizes. Because all air filtration systems are different, one standard media cannot meet every requirement. With three media depths to choose from it is possible to find the right media for any fiberglass application. Contact your Koch representative for recommendations on your system.
Although 1", 2" and 4" Supergrade Fiberglass Air Filter Medias are designed for different applications, several qualities are common to all three styles:
All Koch fiberglass media consists of continuous filaments of high quality spun glass. These fibers are formed into a graded density blanket to provide maximum depth loading throughout the roll or pad.
Each individual fiber is coated with a specially designed adhesive gel. This adhesive enhances the media’s dust holding ability by creating a “wicking” action not provided by competitive medias.
Color Coded Media
All Koch Fiberglass Media is tinted on the downstream side for easy installation into frames or blanket systems.
1" and 2" Media– White, upstream; Blue, downstream
4" Media– White, upstream; Yellow/Gold, downstream
