How Often Change Air Filter?

[addthis tool="addthis_inline_share_toolbox_gcuu"]

Your air conditioner’s filter is what blocks harmful particles from entering your home. Over time, this filter can become clogged and dirty. Contaminants may then enter your home's air supply, resulting in poor indoor air quality.

Poor indoor air quality may contribute to serious health problems, such as:

  • Pulmonary disorders
  • Allergies
  • Respiratory infections
  • Asthma
  • Other health conditions

Thus, replacing your air filter on a regular basis is necessary to protect the quality of your indoor air. Replacing your air conditioner's filter can also help your system run smoother. When a filter is clogged, the air conditioner will have to work harder to keep your home cool. This may cause unnecessarily high energy bills each month.

How Often Should I Replace My Air Conditioner’s Filter?

In general, you should replace your air conditioner’s filter at least once every 2-3 months. However, if you have a pet, or someone in your home has allergies, it may be necessary to change the air filter once a month. For single-occupant, no-pet homes, as well as vacation homes, you may be able to change the air filter just once or twice a year. However, for those with severe allergies, or those who have more than one pet in the house, replacing the air filter once every 20-45 days may be necessary.
