The filter in a forced air furnace protects you and the furnace blower from harmful airborne matter by catching it before it's blown into the house. A new air filter traps large dirt and dust particles and allergens like pollen, mold spores, dust mite debris and pet dander. A dirty air filter greatly reduces furnace efficiency. Replace the air filter at the start of the heating season. Check it monthly and replace it when you no longer can see light through it.
1
Locate the air filter on your furnace. It normally is located in a slot behind a narrow vertical door in the return air duct, just before the air stream enters the furnace heat exchanger to be heated. On some models, the filter is located inside the blower fan compartment and is held in place with clips. It is accessed by opening the fan compartment door. The filter itself is a 1-inch-thick cardboard or plastic frame the same height and width as the air duct, holding flat or pleated filter material. Some furnaces use a box filter that is 4 inches or more in thickness that holds several layers of filter material.

Running Furnace With No Filter
Open the door concealing the filter. Look on the outside of the filter for a part number or the nominal height and width dimensions. If there are no markings, you will have to measure the height, width and thickness of the filter. Purchase a new filter that matches the old filter at any home improvement or hardware store.
3
Turn off power to the furnace so you won’t have it running mid-change. Pull the old filter out of the slot. If the filter is held in place by clips, undo the clips and pull out the old filter. Insert the new filter into the slot where the old filter was; if clips are used, position the filter in the clips and refasten them. Pay attention to the airflow arrow marking on the filter. It should point toward the furnace or toward the fan as you install the new filter.
4
Close the door of the filter slot or fan compartment. Turn the furnace power back on and check the furnace for correct operation.

The first step to an effectively filtered heating, ventilation and air conditioning system is the correct insertion of a furnace filter. If the filter is inserted the wrong way, it will not filter as effectively, airflow will be impeded and the strain on the furnace motor will increase. The first step in air quality, efficiency and proper furnace operation is the correct installation of the furnace air filter.
Determine where on the furnace you can find the filter air box. Stand in front of the furnace and look for the ducts. The heating duct will begin near or at the top of the furnace. Air is pushed through these ducts and into the rooms that the furnace services. The cold air return duct will be attached near the bottom of the furnace. This latter duct is the one that holds the filter air box.
Locate the filter. On most furnaces the filter will be directly adjacent to the furnace. The filter box may be covered by a small and wide hinged door, or the filter itself will be visible inside a notch that it slides into.
Pull the old filter out and discard it. Look on the new filter for airflow arrows that are imprinted along the sides of the filter. These arrows are always meant to point in the direction of the airflow; another way of determining the correct orientation of the filter is that the arrows always point toward the furnace itself.
How to win in roulette. Slide the furnace filter into the filter air box with the arrows pointing toward the furnace. This is the correct orientation when replacing the filter.
Tip
Replace filters every month or when you can no longer see through the filter medium.
The filter air box or the furnace proper will always contain the correct filter measurements for replacement filters. Look for a panel sticker on the inside of the filter air box door or on the inside of the furnace access panel.
Warning
Always turn the furnace off before replacing the filter.
