QUESTION:Furnace Filter?
I hope I am not sounding to stupid, however, I have just moved into a different house & I need to change the furnace filter. Which way does the arrow on the filter go? Does the pleated side go towards the furnace or away.
ANSWER: The arrow indicates the direction of airflow. On the 'better' filters, there is metal screening of some type on the back of the filter, helping to increase the filter's resistance to the force of the air being sucked through it. Not having your filter in front of me, I would say that the pleats face AWAY from the furnace. The filter keeps dust, etc., from being sucked into the motor and dust from being shot back out through the registers/vents.
