Replace Your Furnace Filter

January 15th, 2014 5:28 PM by Eileen Denhard


Replace the air filter on your furnace.


Now, and again in three months (this is minimal for the average home).


Because a dirty filter restricts airflow through your heating system. Reduced airflow can mean uneven heating or cooling, increased fuel bills, and added stress on your furnace




Locate the filter. It's usually where the cold air enters the furnace, near the fan section (see the diagram). At this location, the air is flowing into the furnace. The airflow arrow on the filter should point toward the furnace.

Slide the filter out and note its size. It's written on it somewhere. Buy half-dozen filters from the hardware store.

Replace the filter now and check it monthly. Replace it as needed, but at least every three months. The rate at which they get dirty depends on the number of people, pets and amount of dust in your home.




Mark airflow direction on the ductwork with a marker so that it will be easier to remember the orientation of the filter the next time.



You may want to have the ductwork cleaned to remove the previous owners' debris. Once is enough though -- don't get talked into doing it annually.



Consider an electronic air filter if you have a family member who suffers from allergies or one who smokes. They do a great job of taking very small particles out of the air. But remember, because they do a better job of cleaning, they get dirty faster. They should be cleaned once a month.
