How to Put an Air Filter Into a Home Air Conditioner

If you have a central air conditioner, it is important to change out the air filter at least every few months. Having a clean air filter will not only keep the air free of dust and other particles, but it will keep the air conditioner running at its peak performance level. This saves you money in the long run because the air conditioner is not overworking itself and using additional electricity.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Air filter

1. Locate where in the house the air filter is used. A large vent that can open houses the air conditioner, but the location in the house can vary from the upstairs to the living room.

2. Open up the vent, and remove the current air filter. There is a measurement on the filter that states its size (such as 18x24). If you have a manual for the air conditioner, look for any advice on air filters. The manual may state what filter resistance (thickness of the filter) is best. If you do not have a manual, you should stay with the current kind of filter.

3. Purchase air filters from any home improvement store. Other stores such as Target and Walmart carry a select variety as well. Make sure the measurements are the same as the filter you removed; otherwise it will not fit properly.

4. Place the new air filter into the air vent, and close the vent off. There may be clips or clamps that hold the filter in place (especially if found on the ceiling). The air conditioner should now function properly, lowering your monthly electric bill.

5. Sweep or vacuum up the area around the vent. You probably released some dust from the vent onto the ground when changing the filter.
