It's not uncommon to forget to change your home furnace's filter. It doesn't seem like a priority maintenance issue, until you realize what happens when the filter isn't changed regularly. Changing the filter is a relatively easy chore, and while you should check your furnace manufacturer's recommendation, most brands should be changed every three months.
Before buying a new filter, check the one already installed so you know which size to purchase. There will be a variety of filter types to choose from, with the more effective filters offering HEPA filtration for the highest possible air quality, which is important for those with allergies and asthma.
If your filter is allowed to get very dirty, the air flow in your home will be reduced, and the quality of the air that circulates may become poor. A clogged filter causes your furnace to have to work harder, which increases the cost of operation. If you have pets in the home, you should consider replacing your filter more frequently, as the dander can clog it more quickly.
Once you've purchased your new filter, remove the air filter panel close to the bottom of the furnace to expose the compartment that houses it. The filter will rest on two metal brackets, making it easy to slide it in and out. Pull the old filter out, and put the new one into the unit. Check the perimeter of the filter for an arrow indicating the air flow direction; this will ensure you're installing the filter correctly. The arrow will most often point towards the main part, or the top, of the furnace.
