How Often Should I Change Air Filters?

Regularly changing HVAC filters is essential for maintaining optimal air quality and system efficiency. For most households, it is recommended to check and replace filters every one to three months. Factors such as the type of filter used, the level of pollutants present in your environment, and the usage patterns of your HVAC system play significant roles in determining the frequency of filter changes. High-efficiency filters may last longer but should still be monitored closely.

In homes with pets, or where occupants suffer from allergies, more frequent replacements—approximately every month—are advisable due to the increased volume of dander and other allergens. During peak seasons, such as summer and winter, when HVAC systems are under more strain, it may be beneficial to inspect filters even more regularly. Clean filters allow for better airflow, reducing the load on the system and potentially lowering energy costs.

Neglecting to change HVAC filters can lead to several problems, including reduced air quality, increased energy bills, and even system breakdowns. Clogged filters restrict airflow and force your system to work harder, which may shorten its lifespan. Establishing a routine for checking and replacing filters is a proactive step that not only enhances comfort but also promotes the longevity and efficiency of your HVAC system.
