Changing your furnace filter is a simple process. All you need to do is slide the old one out and slide the new one in. Make sure  that the air flow arrows point toward the furnace or blower motor when putting in the new one.  Use the old one for a guide if you need to.  It never hurts to be sure. (Assuming the previous filter changer had it in right)

All of the filters we sell are 1/8"-1/4" smaller than the stated size to meet the industry standard, and make it easier to remove and replace the filters. If you run into problems during the process please call 914-330-2447 and ask for Kitty. I will do my best to assist you over the phone.
