A pleated filter is an air filter that uses a folding pattern with its media (hence the name “pleated” filter). ... In other words, pleated filters can collect more particles than standard throwaway filters without increasing your air conditioner's energy consumption.

Is a pleated filter better than a non-pleated filter?

A pleated filter is made up of different sizes, and readily captures pathogens as small as 0.3 microns, filtering out even the tiniest of bacteria. They are overall more effective in capturing very tiny particles than non-pleated air filters; 99.97% of airborne particles are trapped with a pleated air filter.

Why are pleated filter better?

Catch more debris: Pleated air filters have more surface area, so they capture more – and smaller – debris. Depending on the MERV rating, they may filter out pollen, pet dander, bacteria, and some viruses. This makes a pleated air filter a much better choice for anyone with allergies, asthma, or similar sensitivities.
