These are the things that most impact how long a filter lasts.

You smell burning near the HVAC unit
Running more frequently than normal
You have pets
Home is more dusty than normal
You are a smoker
Changing your furnace filter regularly ensures the air in your home will remain clear of dust and other contaminants. If you don’t change your filter, it will fill up and won’t be able to trap new particles. A full filter will not be able prevent additional dirt and debris from circulating through your home, causing your family to breathe more dust and allergens on a daily basis. Additionally, a full furnace filter causes the motor on your furnace/hvac system to have to work harder, and it will subsequently become less efficient.

Keeping new filters in your furnace will help ensure that your furnace runs smoothly and efficiently and, most importantly, the air you and your family breathes is as clean as possible.
