How Often Should I Change my Furnace Filter?
There are many different kinds of furnaces, and each has its own unique filter size, shape, and life cycle. Know your furnace filter size. As a homeowner it’s important to always have a few on hand. Use a marker and write the date on it when you put it in place. When you mark the date on your furnace filter will know how long it’s been in place, and get a better idea of when it’s time to replace it. A good habit to get into would be to check it monthly.
The disposable, inexpensive furnace filters will typically need to be replaced every 4 to 6 weeks, or whenever they get too dirty to function properly, or according to manufacturers recommendation. How can you tell if it is too dirty? Take the filter out and hold it up to the light. If you can mostly see through it, it’s still clean enough to function properly. If you can’t see through it, it’s time to change it.
Do you know what direction the air is flowing through your furnace? If you’re not sure, ask your HVAC serviceman to show you. Mark your furnace with an arrow and write “Air Flow”. Inexpensive filters may also have an arrow or “Air Flow” marked on it. Make sure to place the filter in the proper orientation.
