One way to save money on your energy bills and help your furnace run more efficiently is by changing the furnace air filter at least once a month or as recommended by the manufacturer. What can happen if you don’t change it? The air in your home will be dirtier, and so will you. Let’s take a look at how dirty furnace filters impact health, homes, and budgets.
Reduced Airflow
When a furnace air filter is clogged with dirt and debris, it can seriously obstruct necessary airflow. This prevents the furnace from circulating the volume of air required to keep the house comfortably, efficiently, and economically heated or cooled.
Health Issues
A dirty furnace filter can be a breeding ground for bacteria and allergens, which can cause respiratory problems and other health issues.
Higher Energy Bills
The dirtier and more clogged a furnace air filter becomes, the harder the furnace has to work to circulate the air, and this costs you more in electricity and fuel in the long run. In fact, according to Energy Star, a dirty furnace air filter can increase energy bills by 5% to 15%.
Premature Furnace Failure
One of the most common problems associated with a dirty furnace air filter is premature furnace failure. When a furnace needs to work harder and longer than necessary, the extra strain can lead to a costly breakdown and the potential need to replace the entire unit.
Selecting a Furnace Air Filter - Size and Style
When it comes to furnace air filters, there are a variety of different types available on the market. The most important factor to consider when selecting an air filter is the size of your furnace. You want to make sure you get a filter that is the correct size as recommended by the furnace manufacturer.
Another thing to keep in mind is the type of furnace air filter you select. The most common type of filter is the pleated furnace air filter, which is made of fiberglass or synthetic material. These filters are designed to trap dust and other particulates, making them ideal for people with allergies or respiratory problems.
If you have pets, you may want to consider a HEPA air filter. There are multiple products available. Do your homework to select the furnace air filter that works best for you. These filters are designed to remove 99.97% of all particles from the air, making them ideal for people with pets or allergies.
Summary
It's important to replace your furnace air filter on a regular basis, preferably every month, or as recommended by the manufacturer. A clean furnace air filter will help ensure your furnace is running efficiently and also help keep your home healthy. A dirty furnace filter can cause all sorts of problems, from increased energy bills to respiratory problems. So be sure to change your furnace air filter regularly and keep your home happy and healthy.
