Changing the air filters in your HVAC system is an essential practice that ensures clean and healthy air circulates throughout your house.


All of the heated air that flows from your furnace into the living spaces of your New Jersey home must first pass through an air filter. If the filter is dirty with contaminants, the air will filter through those pollutants as well. Air filters don’t just help improve the air quality of your home, however. They protect your heating system equipment from damage, too. The Environmental Protection Agency calls changing your furnace filters whenever they become dirty the most important maintenance task that you can do to optimize your heating system’s energy efficiency.


Energy savings, lower utility bills and better indoor air quality are the three greatest benefits that you’ll enjoy when you change your furnace filters whenever they’re dirty. An understanding of the role that air filters play helps explain why they’re so important:

  • Air flow. Even the most energy-efficient furnace can’t keep your home snug and warm without a well-operating air distribution system. The heat that your furnace generates is directed into the ductwork with a blower, which is typically a fan with a rotating wheel that draws in and blows out air. If an air filter becomes so clogged and dirty that it restricts air flow, the blower will pull in air from any leak or crack in the air handler or ductwork, impacting your home’s indoor air quality. Dirt can also accumulate on the coils and further restrict air flow.
  • Heater performance. Dirty filters can cause dust, grime and debris to build up on heater components, which can impair the efficiency of the entire heating system. Over time, the heater’s performance weakens while the energy usage steadily increases. Replacing a clogged filter with clean one can lower an HVAC system’s energy consumption by as much as 15 percent, according to the EPA.
  • Indoor Air Quality. Filters are rated according to the number and size of particles that they can trap. The rating system used is called the Minimum Efficiency Reporting Value (MERV) scale. The higher the MERV number, the better the filter is at removing tiny particulates. Because high efficiency filters are made with denser materials, however, they can impair air flow. An expert from Hollub Heating can help you select the filter best for your heating system.
