Metal Framed Pleated Panel Filters – High Moisture Solution

It is a common sight on fresh air supply systems to see cardboard framed panel filters that have collapsed due to high moisture content from weather conditions including rain and humidity. When moisture gets into the cardboard frame its rigidity can fail causing the filter to deform and sag in the filter frame. In worst case scenarios the panel filter can fall out of its frame entirely with catastrophic consequences.

The amount of moisture in the duct is often dictated by how close to the fresh air inlet, a panel filter is located and there are a few options available to a designer / contractor / FM engineer to solve the problem, with a simple change in the air filter being used.

Air filter manufacturers often offer a range of air filters manufactured from “Beverage Board”, (a cardboard often used in the catering industry) as it is a moisture resistant material. This obviously can offer advantages in a supply air duct, but can still perish over extended periods of high humidity. Pleated and glass panel air filters manufactured from beverage board typically are available for around double the cost of standard cardboard framed panel filters.
