Just like your air conditioning unit, your furnace has a filter too. The furnace filter keeps dust and other debris from circulating in your house, and keeps the indoor air quality at a healthy level. Your can get either one-time use filters or reusable filters for your furnace. One-time use filters cost about 50 cents each when bought by the box, and reusable filters cost about $20 each and can last for up to 5 years. In either case, you should dispose of or wash you furnace filter once a month during the winter. This will not only keep the air quality better in your house, it will also save energy, up to 5 percent. This in turn will save you on your energy bills. Make sure you measure your air filter before you go shopping for one, as you don’t want to end up with the wrong size. Furnace air filters range from 12×12 inches to 30×30 inches in size.
