Be sure you have measured your existing filter before placing an order, some manufacturers undercut filters so you should never base it off the label. Exact/custom filters are not eligible for returns or exchanges. Manufacturing tolerances of plus 0, minus 1/8" will be observed on overall width and length of filter. Picture is used as a reference, sizes will vary. Filters larger than 25x30x1 are considered a double filter where there is additional strength down the middle of the filter. It's our policy to list the smallest dimension first. When the filters arrive the label will be displayed as such, this will not impact compatibility - it's just a matter of how you hold the filter. If you have questions or concerns please contact us.

MERV Rating: MERV 11

Nominal Size: 18 x 20 x 1 inches

Actual Size: 18 x 20 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 11 rating reduces up to 90% of airborne particles as small as 1 micron including dust and lint, dust mite debris, pollen, pet dander, mold spores, bacteria, virus carriers, as well as most smoke and smog.

Quantity: 12 Filters

Part Number: MERV 11 - 18 x 20 x 1 - E
