How Often Should You Change Your Furnace Filter?


If you have a furnace in your home, you probably know they need regular maintenance to keep them running properly. One important part of furnace maintenance is changing the filter regularly. The furnace filter is an important part of your home’s heating and cooling system. It helps to keep the air clean and free of particles that can cause problems with the system.

When should you change your furnace filter?

A furnace filter is a device used in furnaces to remove dust and other particulates from the air. The filter is typically a pleated paper filter placed in the furnace’s air intake. The filter catches the dust and other particles as the air is drawn into the furnace. This helps to keep the furnace clean and prevent the buildup of dust and other debris on the furnace’s heat exchanger.

The general rule of thumb is to change your furnace filter every three months, but this varies depending on the type of filter you have, the size of your home, and the number of people living in your home. If you have pets, smoke cigarettes, or have allergies, you will need to change your filter more often. However, the Department of Energy recommends changing your furnace filter every month. Not only does this keep your furnace running efficiently, but it also helps improve your home’s air quality. A dirty filter can cause the furnace to work harder and can lead to increased energy costs.

How to know when it’s time to change your furnace filter?

Changing your furnace filter every three months is recommended, especially during the winter when your home is using the furnace more frequently. A dirty filter will restrict airflow and decrease efficiency, costing you more money in energy bills. You should also change your filter if it’s visibly dirty. Hold it up to the light to determine if your filter needs to be changed. If you can’t see through it, it’s time for a new one.
