The Importance of Clean Air Filters for Your HVAC System

You might be under the impression that because you’re indoors, the air quality is better than you would get outdoors. Unfortunately, sometimes the air we breathe in our own homes is even more polluted than a busy city street, because many of us forget the importance of regular HVAC service in St. Louis, MO. Pollen, pet hair and dander, mold, dust and other pollutants can make it difficult to breathe easily. In fact, that’s why your HVAC system has an air filter—but in order for it to be effective, you need to change it regularly.

Air filters not only filter the air you breathe, making it possible to live without congestion, but they also function in blocking particles and pollutants that could damage the inside of your HVAC unit. Changing your air filter is a relatively simple process—it should take less than 10 minutes to complete—and will drastically improve the function of your HVAC system.

Types of air filters

There are a variety of different air filters you can purchase for your unit. Here are some of the most popular options:

  • Fiberglass: These are the least expensive filters you can purchase. They’re disposable, and often do a decent job of protecting your HVAC, but will stop working effectively as debris builds up. If you’re prone to allergies, try a different type.
  • Pleated: The more pleats, the better the filtering—these cotton or polyester filters do a nice job of filtering dust and allergens.
  • Reusable and washable: Washable filters are greener than other options, and save you money in the long run. It’s important to follow the manufacturer’s directions for washing the filters and letting them dry completely, or you could find yourself blowing mold throughout the house.
  • HEPA: HEPA stands for “high efficiency particulate air filters,” and these filters are great for those with seasonal or chronic allergies and respiratory problems. They can filter out 99.97 percent of contaminants, making them the U.S. Department of Energy’s top choice of air filter.
  • Electrostatic: These come in washable and disposable versions, and use an electrostatic charge to trap dust and other particulate matter.
  • UV: Finally, these filters use UV light to kill bacteria and viruses that enter your home. They’re not as effective in screening dust and other particulates, but if you’re constantly sick, this could be a good choice for your home.
