How Often Should You Change Your Air Conditioning Filter?

Tips To Change Out AC Air Filters

Air conditioner filters do need to be replaced regularly in order to ensure that the air circulated in your home is fresh and healthy, but the replacement interval depends on many different factors – here are some:

  • The type of the filter – the basic, removable air filters that you can find in any store around you should be replaced every 30-60 days, but there are filters that allow for longer intervals and some that can be cleaned and reused;
  • The environment – the filters used in buildings in urban areas that get lots of traffic and air pollution need more frequent replacement than a rarely visited vacation home in the mountains where the air is fresh;
  • The presence of household pets – if you own a dog or a cat, make sure that you don’t use the same filter for longer than 60 days. If you own multiple pets, replace the filters in your A/C unit every 40-45 days;
  • Allergies or chronic respiratory illnesses – if anyone in your household suffers from conditions that affect their respiratory system, the filters need to be replaced every month to ensure that the air they breathe in the house is clean and free from germs, dust, pet hair or any other allergens that might trigger seizures or discomfort.  Ask a Local Denver HVAC company for routine inspections.
