Homeowners looking to save money on their heating bills should consider cleaning their furnace filter regularly. It’s an easy and cost-effective way to improve indoor air quality and reduce energy consumption. In fact, a clean furnace filter can lower heating bills by 5 to 15 percent.

If you reside in a colder climate, chances are your furnace is a significant source of energy usage throughout the winter season. That’s why it’s essential to inspect your heater’s filter each month during this time. If you’re still using disposable fiberglass filters, consider investing in a reusable one. They’re environmentally friendly and more efficient than their disposable counterparts. You can purchase a decent reusable filter for under $50, making it a worthwhile investment.

How to Clean Your Furnace Filter

Start by turning off the power to your furnace. Look for the service panel, and open it using a screwdriver if necessary. Locate the furnace by the intake-outake blower. The filter looks like a sponge. Pull it out and inspect it. If you can’t see through it, it’s time to clean it. Even if it doesn’t look that dirty, it’s best to clean it anyway.

Take the filter to a utility sink or bathtub and rinse away the dust. Alternatively, you could take it outside and rinse it off with a hose or rain barrel water. Once it’s clean, wait for it to dry before putting it back into the furnace. Congratulations, you now have a clean, energy-efficient furnace filter.
