Custom Filters for Custom IAQ

At Air Defense Filters, we have been in the industry for so long; we understand that every HVAC system is unique, so we offer custom air filters to fit any size or shape. You can choose from a range of MERV ratings, starting at MERV 5 up to MERV 13.

In 2020, we invested in new equipment and a new facility to allow us more accuracy in the dimensions of your filter with SUPER fast turnaround. Yet, even with the further expansion and investment, we are EXTREMELY competitive.

Air Defense Filters is committed to providing our residential, industrial, and commercial customers with the best possible air filtration solutions. If you have any questions, please get in touch with us. We are always happy to help!

Custom-size air filters are built to your exact specifications. As a result, these filters may not be returned for refund or credit. All custom-size air filters are built to tolerances of + or - 1/8".

Most air filters are stamped with a size that is NOT the actual dimension of the filter. Please measure the filter yourself to get the accurate measurement you need.

We are one of the only manufacturers that make custom filters starting and ½” up to 8” in depth. Need something other than that? Just contact us. We have a staff of CAD Engineers on hand to help guide you to what you need with the most affordable solution.

Pleat Consistency

PROPRIETARY NON-LAMINATED PROCESS

Air Defense uses intricate techniques in production control that will provide an efficient pleat count, height, shape, and spacing. A proprietary non-laminated process creates a high dust holding capacity with an extremely low-pressure drop.

Durability

VARIETY OF OPTIONS

The pleats have a moisture resistant media and construction that will hold together even when wet. Protecting it from extra buckling, collapsing, racking, warping, and bending. The galvanized steel metal grid even in the rough conditions will hold to its shape, withstand rust, and prevent fluttering.

Compare

NEW STANDARD

The Air Defense line has an equal to or lower than the initial resistance levels to assist in being energy efficient. Additionally, it also out performs other standard and/or high capacity pleats, focusing on lower pressure drop and high dust holding. See the comparison chart.
