How Does A Panel Filter Work?

July 20, 2021

If you have been searching for the right air filter for your HVAC or furnace, you most likely will have come across panel filters, the most popular type of filter available in the market. Panel filters look very simple but are very effective in removing dust and other air particulates. They do so through a negative pressure system that traps the particles, ranging from 1 micron up to 0 microns in size. These particulates include the following:


  • Mites
  • Moulds
  • Pollen
  • Pet dander or fur
  • Soil and lead dust
  • Nebulizer droplets
  • Fabric and textile fibers
  • Legionella
  • Auto exhaust particulates



The main purpose of a panel filter is to protect the mechanical parts of an HVAC system from getting damaged due to impurities in the air.



When utilized in housing vents, panel filters are capable of extending the service life and internal air quality that circulates inside your home or facility. So, how is a panel filter exactly able to do this filtration task?


First, the fan draws in the ambient air into the filter media using negative pressure. Once the air passes or comes into contact with the air filter’s surface, the element starts to do its task of cleaning the air, trapping the impurities in the filter. The element is then able to trap any particles that are bigger in size than the pores of the filter itself. Bigger particles are first carried into the filter through inertial mass effect while lighter impurities are intercepted by the filters. Finally, the remaining tiny particles are removed by the filter through diffusion.


Why use a panel filter? First and foremost, it is capable of protecting the most delicate parts of your system while giving you better air quality to breathe. If you are not careful about removing all those contaminants from your system, they can cause the fans, coils, motor, and sensors of your HVAC system to work harder, which can speed up system deterioration.
