Extremely important. It keeps the evap coil from being plugged up with dirt, hair etc. Also if that air wasn't filtered you would be blowing dirt and crap all over the house.

As for the outside air coming in you need to filter even more because of it as the outside air is full of dirt, pollen etc.

Basically it's for the equipments health your health as you shouldn't be breathing that stuff in and for keeping your house clean.
