With winter dead upon us we need to do all we can to maintain our furnaces inside of our own homes and those we wish to sell. Nobody wants to buy a home with a poorly working furnace and one of the best ways to keep it running smoothly is to change the filter regularly. Not only will this allow the furnace to run more efficiently but it will also cut down on the amount of dust in your house.
Changing or cleaning a furnace filter is quite simple to accomplish. Simply pull the old one out and pop the new one in. If you have a reusable electrostatic filter you can clean it using a garden hose or blow the dirt out with compressed air. If not, simply replace it. A standard filter requires replacement every month. An Electrostatic disposable filter can last about three months before it requires replacement.
