How Often To Change Air Filters for Residential Homes with Indoor Animals?

The addition of indoor animals complicates the equation determining how often to change air filters. How?

Indoor animals contribute additional pathogens and particles into home air. The air filter fights against materials like:

  • Additional organic waste like dirt, dust and trash
  • Viruses
  • Bacteria like salmonella and staph
  • Dander, hair
  • Insects, ticks, tick-borne bacteria

If homeowners share the home with one indoor pet, heating contractors recommend changing air filters every 60 days.

If there is more than one indoor animal, change air filters every 20 to 45 days. HVAC contractors recommend the same for those with allergies or other respiratory sensitivities.

Keep in mind that air filters are very good at their jobs. The typical air filter captures up to 50 percent of all airborne particles when the air conditioner or heater runs. The addition of pets increases the amount of particles and pathogens in home air, which means that air filters work harder to remove more.

Owners of vacation homes or homes with only one occupant and no pets are advised to replace air filters every six to 12 months. Because these homes experience little activity and invite few contributors to indoor air quality, air filters do not need to be changed very often.

However, these homeowners run the risk of forgetting how often to change air filters because it is seldom that air filters actually need changing. In order to ensure that these homeowners keep up with how often to change air filters, schedule a reminder or an HVAC maintenance appointment.
