Actual Size: 19 1/2 x 21 x 3/4 inches

Media: 100% synthetic non-woven, proprietary media that can be recycled. Engineered with a gradient density composition that achieves it's MERV rating using the mechanical method of particle capture. Media does not rely on an electrostatic charge to capture particulate, since electrostatic charged filters dissipate over time.

Frame: Heavy-duty, two piece, moisture-resistant frame with diagonal support members. Frame is bonded to the media at all points of contact for unsurpassed frame strength. Interlocking corners and positive media-to-frame seal reduce the possibility of air bypass.

Support Grid: Expanded metal is continuously laminated on the air leaving side to provide pleat stability during operation. Pleat shape is maintained allowing full media utilization which improves dust holding capacity.

Replace: Recommended 90 day changeout

Removes: MERV 13 rating reduces up to 95% of airborne particles including dust and lint, dust mite debris, pollen, pet dander, mold spores, bacteria, microscopic allergens, virus carriers, most smoke, smog, oil smoke, as well as lead dust. Hospital-grade air filtration provides maximum protection for your home or business.
