If you want your furnace to keep your home warm and your energy bills in check, changing your furnace filter regularly is a must. A clogged or dirty filter forces your heating system to work harder, reducing efficiency and leading to higher costs—or even unexpected furnace replacement expenses. But how often should you swap out your filter? The answer depends on several factors, including the type of filter you use, your home environment, and how frequently you run your heat.
Let’s break it down so you can keep your heating and cooling system running smoothly all winter long.
How Often to Replace Your Furnace Filter
1. What Type of Filter Do You Have?
Not all furnace filters are the same. Here’s a quick guide on how often each type should be changed:
- Fiberglass Filters – These basic filters should be replaced every 30 days.
- Pleated Filters – A better option for trapping dust and allergens, these last 60 to 90 days.
- HEPA or High-Efficiency Filters – Designed for maximum air quality, these can last up to 6 months, but they need regular checks.
2. Do You Have Pets or Allergies?
If you have pets, you’ll need to change your filter more often. Pet hair, dander, and dust can clog your system fast. If anyone in your home suffers from allergies, swapping out your filter every 30 to 60 days is a smart move.
3. How Often Do You Use Your Furnace?
During peak heating months, your system is working overtime. More use means faster buildup in your filter, so replacing it every 30 to 60 days can help maintain efficiency.
Why Changing Your Furnace Filter Matters
Swapping out your furnace filter regularly can:
✔ Improve indoor air quality by reducing dust, pet dander, and allergens.
✔ Boost efficiency so your furnace installation lasts longer and runs better.
✔ Lower energy bills by keeping your heating system from working too hard.
✔ Prevent costly repairs and avoid premature heating replacement needs.
