When Should You Change Your Furnace Filter?

When Should You Change Your Furnace Filter?You have noticed cat fur accumulating around the legs of your kitchen chairs and a white layer of dust settling on all your wooden furniture more than usual. You start to wonder if it is time to change your furnace filter.

Exactly when are you supposed to change your furnace filter?

Here are the reasons and indications that will offer you a clue that it is time.

  • if your windows and doors are open regularly, allowing pollen and dust in
  • it appears that your home has a steady-to-abundant amount of dirt and dust buildup
  • if there are individuals who smoke in the house
  • you run your heating system fan frequently
  • your present filter has a noticeable accumulation of dirt and dust
  • you notice the filters are clearly dark and clogged
  • you own pets that shed fur continuously

On average there are three types of filters that should be replaced on a monthly or bi-monthly basis. They are the basic, fiberglass and paper furnace filters. If you have an electrostatic or “high efficiency particulate air” (HEPA) filter then you should replace them every two to four months.

However, not all people’s homes or daily habits are identical. If you do own a number of pets, or there are smokers in your home it is recommended you should change the filter more often than the average time frame indicated.

Replacing your filter is the simplest way to maintain clean air in your home and your heating system to remain as efficient as possible.
