Are you seeing a preponderance of dust bunnies in your home? Is dog hair blowing across your hardwood floors and piling up in corners? Do you notice yourself sneezing more than usual while in your home this winter? If you answered yes to any of these questions, then most likely you need to replace your furnace air filter if your home has an HVAC heating system.

Furnace filters are specifically designed to trap dust, dirt and other airborne particles in your home. Besides making the air you breathe in your home cleaner, furnace filters also help to increase the longevity of your furnace system by preventing dust and dirt particles from damaging your furnace's fan and heating coils.

Replacing your furnace filter three or four times a year is a smart idea. Besides keeping your home warmer during the winter months, it also will help to reduce your home's heating bills by maximizing the efficiency of your HVAC furnace system. Moreover, replacing your furnace filter will help reduce airborne dust particles in the home. And if you have allergies, particularly ones caused by airborne dust mites floating around your home during the winter months, you can purchase air filters specifically designed to capture them. Other higher-end furnace air filters are also designed to trap bacteria, pollen, mildew and mold spores.

Furnace filter replacement is a very simple and inexpensive task. All you have to do is swap out the old one with a new one. Prior to buying a new furnace filter, inspect your furnace and pull out the existing furnace filter to record its dimensions. In most cases, the filter dimensions are listed right on the filter.
