Furnace Filter?

I hope I'm not stupid survey, however, I just moved to another house and I need change the furnace filter. Which way does the arrow on the filter go? Is the party going into the pleated furnace or traveling.

The arrow indicates the direction of airflow. In the "best" filter, it is metal detection from one type to the rear of the filter helping to increase the resistance of the filter to force air sucked through it. Not having your filter in front of me, I would say that the folds face away from the furnace. The filter prevents dust, etc., to be sucked into the engine and the dust from being drawn back to through the registers / vents.
