This is your sign to change your furnace filter.
If you can't remember the last time you replaced it... it's probably time.
A clean furnace filter helps:
✔️ Improve airflow throughout your home
✔️ Reduce dust, pet dander, and allergens in the air
✔️ Lower strain on your HVAC system
✔️ Improve energy efficiency
✔️ Extend the life of your furnace
Most homeowners should check their filter every month and replace it every 1–3 months, depending on pets, allergies, and household activity.
