How Often Should I Change The Air Filter In My Home

How Often Should I Change The Air Filter In My Home?

Checking Your Air Filters is the single most important and cost effective thing you can do for your central heating & air conditioning system.

We suggest checking filters at least once every 3-6 months. If you have a disposable filter and it’s dirty, replace it. Don’t attempt to clean it. In the higher-use seasons, it’s better to check at least every three months.

Your air filter is usually located in the return air duct next to the furnace or indoor unit. Or, it’s located next to the blower motor inside the furnace. Some systems have a central filter installed in a wall or ceiling. If you’re unsure and would like to change it yourself, ask your technician to show you on your next service call. We’ll be happy to help.

Air filters are directional. The air flows through the filter in one direction only. Look for an arrow or airflow symbol indicating the direction to install the filter. The arrow should point towards the furnace or air handler.

For different types of homes, here are some different times you should change your air filter at home:

  1. An average suburban home with no pets should be change every 90 days.
  2. With a car or dog, change your filter every 60 days
  3. With more than one pet or if residents have allergies, change every 30-45 days
  4. A vacation home or single occupant home with no pets or allergies can be changed every 6-12 months

These are personal recommendations from Midwest and it’s what we do in our homes. The longer you’re in your home, you’ll be able to determine how often to change your filter based on how dirty it is during different times of the year. In Kansas City, you’ll notice an increase in build up of dust during the winter and summer months. Definitely change it before the cold winter and hot summer kicks in. You, your family and your furnace and air conditioner will thank you.
