Why Do I Need to Change my Furnace Filter?

1.) Protect Your Furnace 

  • Your furnace filter’s primary function is to protect your home’s heating and cooling equipment – blocking dust, particles, and debris from entering the furnace’s blower motor. It is only an added benefit that it also ends up cleaning the air that you breathe, contributing to good health and well being for you and your family.

2.) Save Money & Extend the Life of Your Furnace

  • As your filter collects various pieces of dust, pet dander, pollen, etc., the filter begins to get clogged with debris. Over time, the dirt builds up to the point where it effects the amount of air that the furnace is able to pull through the filter. In turn, this makes the blower motor work harder to get the air – increasing your electricity bill and eventually causing your blower motor to over heat and dramatically decrease its life expectancy. In addition to the expedited energy costs, it will also take longer to heat your home, which is never pleasant when its freezing outside.

3.) Keep Your Lungs Happy & Healthy

  • Your furnace filter catches many pollutants, allergens, toxins and other particles out of the air. Keeping up with filter changes will ensure that your filter catches as many particles as possible!

It is recommended to change your filter every 1 to 6 months depending on the type of filter you have.

  • If you have a standard 1″ filter, change it monthly, as these fill up very quickly with dirt and debris.
  • As a general rule, if you have 3″ filters (or thicker), or a filter with a high MERV rating, such as an 8 or higher you can wait every 6 months to a year  to change it.

However, the frequency of changes really is specific to each homeowner. If you don’t have any pets, don’t live near construction and don’t smoke you can tend to leave your filter in for longer – it all depends on the air quality within your home.
