Air filters should generally be changed every 90 days for a typical home. However, if you have pets, or if anyone in your household has allergies, it’s advisable to change filters every 30-60 days. For homes without pets and allergies, extending it to every 90 days is acceptable. In high-usage months, such as during summer or winter when HVAC systems are often running, checking filters monthly and replacing them as needed can help maintain clean air flow and optimize your system’s efficiency.
