Get to Know: Air Filters

Infographic on Air Filters

We all know that air filters are an important component of the HVAC system. But many people probably don’t realize that these cardboard-looking boxes full of fibers and pleated material actually affect several crucial areas of your indoor comfort and HVAC performance. So, for all of our friends, our team at Advance Mechanical Heating and Air Conditioning is going to help you get to know air filters.

Let’s start with the basics. The primary function of air filters is to clean the air that circulates through your heating and cooling systems. Remember, filters equal filtration. They hold and trap many types of particles that can affect your indoor comfort and health, like:

  • Dirt and dust
  • Pollen
  • Mold
  • Hair (including animal hair)
  • Bacteria
  • Fibers and lint

It is important to note that not all air filters clean your air with the same level of efficiency. Filter performance is represented by its MERV rating, which stands for minimum efficiency reporting value. MERV ratings range from 1 to 16. The higher the number the better the filter removes materials from the air. For even cleaner air, beyond filters, you can also install other filtration systems and purification units along with your HVAC system.

Air filters come in different sizes. One size does not fit all. If you are unsure of what filter is best for your heating and cooling system, we can help!

Air filters should be checked and changed every month. Don’t vacuum the filter! Not only does regularly replacing your filters help to maintain clean air in your home, it also helps to prolong the life of your HVAC system. A dirty air filter is the #1 cause for HVAC failure. Not to mention, a system with a dirty filter has to work harder to maintain a comfortable indoor temperature. Thus, dirty air filters increase energy bills!
