Disposable Fiberglass Air Filter, 18 x 36 x 1 in.

This disposable fiberglass air filter is designed for commercial and industrial users needing filtration for light- to medium-duty applications. It helps support routine air-quality maintenance by capturing airborne contaminants as air moves through compatible filter openings.

Measuring 18 x 36 x 1 inches, this filter uses progressively dense glass-fiber media, with coarser fibers on the air-entry side and tighter fibers on the air-exit side to promote depth loading across the media. A non-migrating adhesive coats the fibers. The media is secured on both sides to a one-piece moisture-resistant craft-board frame with thermoplastic sealant, while interlocking mitered corners add strength. No additional metal support is used.

Key Features:

• Progressive-density media: Uses coarse-to-tight glass fibers to support depth loading and fuller use of the filter media.
• Adhesive-coated fibers: A non-migrating adhesive helps enhance filter performance.
• One-piece frame: The moisture-resistant craft-board frame provides strength and supports installation.
• Mitered frame corners: Interlocking corners add durability for commercial and industrial handling.
• Sealed media-to-frame bond: Thermoplastic sealant on both sides helps prevent air from bypassing the media and adds rigidity.

Choose this 18 x 36 x 1 inch disposable fiberglass filter for light- to medium-duty commercial or industrial filtration needs where a framed, easy-to-install replacement filter is required.
