Filter Systems

Most forced air furnaces use filters to help clean the air that is distributed through the house. The most commonly found filter is the disposable kind which costs under two dollars a piece and is produced in various sizes. I would recommend that a box of such filters be purchased in the appropriate size for a particular furnace and that the filters be replaced every six weeks to three months during the heating season.

Many gas furnaces use washable filters. Such filters can be cleaned by a hose, in the laundry tub, or in the dishwasher. The most efficient way to clean the air circulated by a forced air furnace is by the electronic air filter. The installation of such devices requires some modification of the duct system at the furnace. The maintenance of the electronic filter is vital to its proper operation and should be performed approximately every 60 days.
