How Often Should You Replace Your Home Air Filter?Updated 2 months ago

The type of air quality you need in your house and the workload of your HVAC system should be considered when determining how often to change your air filter. High-efficiency filters usually last longer than standard fiberglass filters, which need to be changed every month. You’ll need to switch out your air filter more often if you have a pet, or have someone living in the home who is a smoker or who has allergies.
