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

Action Air provides some basic information on how often you should change your air filter and why it’s important.

How often should you change your air filter?

  • If your home is occupied all year round, Action Air recommends changing your air filter every 60-90 days.


  • Save money on repair costs
    • Over time, your filter collects the dust, dirt, pet dander, and other air contaminants that float around your home.
    • A dirty air conditioner can lead to a serious strain on your system and that extra work results in much-needed repairs.
    • Reducing this strain could possibly save you thousands of dollars.
  • Save money on cooling bill
    • When your air filter is dirty and clogged, your HVAC unit has to work harder and this extra work uses up more electricity.
  • Pets affect your air filter
    • If you have dogs or cats into your home there could be pet dander and fur floating which can clog your filter much sooner so you might want to change it more often.
  • Improve your indoor air quality
    • If you’re an individual who suffers from extreme allergies, know this:
    • A clean air filter means you can stop breathing in dust mites, and other tiny particles.

Which filter should I use?

  • Size
    • Every home has a different return size.
      • Check the size of your current air filter to get the right fit.
  • Pleats
    • Look for a pleated air filter instead of a single sheet of fiberglass.
  • Look for the MERV Scale 
    • The higher the MERV rating the better the efficiency.

You can live a healthier life and extend the lifespan of your HVAC when you make this simple task of replacing your air filters regularly.
