It is recommended to replace them every 90 days if you don't have allergies, but AC professionals generally suggest changing them every 45 days for maximum efficiency. In general, most air filter manufacturers and HVAC companies advise changing the air filter every 90 days or 3 months.
This may vary depending on the location of your home (e.g. EJ. dry and dusty climates), if you have pets and the age of your system and equipment. If you have pets in the house, you should consider replacing the filter every 60 days or 2 months, and for households with multiple pets or people with allergies or respiratory conditions, it is recommended to change the filter every 20 to 45 days.
Vacation homes or vacant homes that don't have much use can usually wait to change filters every 9-12 months.
