- Home Size
if you live in a “smaller home” your AC and Furnace pumps less air for the same amount of temperature change which could mean fewer filter changes. However, if you have a smaller appliance used to cool the space, it probably means you have a smaller filter which means you’d need to change it more frequently - Air Quality
if you have poor air quality outside, you’ll need to replace your air filter more frequently as your outside air affects your inside air - Pets
Household pets can shed and track dirt inside the home easily. Because of this, you’ll need to change the air filters more frequently to keep the air clean of pet air and dander - Allergies/Medical Conditions
If you have severe allergies or medical conditions like asthma or other respiratory conditions, you can consider changing your air filters more frequently
