What Are the Differences Between Pleated and Non-Pleated 20x20x1 Air Filters?

When it comes to air filters, there are a variety of options available. One type of filter that is commonly used in residential HVAC systems is the 20x20x1 air filter. But what exactly is the difference between pleated and non-pleated versions of this filter? Let's take a closer look.

What Is a 20x20x1 Air Filter?

A 20x20x1 air filter is an air filter that measures 20 inches by 20 inches in size and is 1 inch thick. This type of air filter fits most standard residential air filters, making it ideal for use in homes.

Pleated vs. Non-Pleated Air Filters

The primary distinction between pleated and non-pleated air filters lies in their surface area. Pleats are folds made up of multiple layers of material, which increases the surface area of the filter compared to its non-pleated counterpart. This allows pleated filters to trap more particles than non-pleated ones.

Advantages of Pleated Air Filters

The increased surface area offered by pleats gives them several advantages over non-pleated filters. For one thing, they can trap more dust, pollen, pet dander, smoke particles, and other airborne pollutants than their counterparts can. Additionally, they last longer because they don't need to be replaced as often due to clogging.
