Changing Your Furnace Filter: A Simple Step for a Healthier Home

When was the last time you changed your furnace filter?

If you had to think about it…it’s probably time.

Changing your furnace filter is one of the easiest and most affordable ways to keep your home’s air clean and your HVAC system running smoothly. But it’s also one of the most commonly forgotten tasks. Let’s break down why it matters - and how to do it in just a few minutes.

Why Changing Your Furnace Filter Is So Important

Your furnace filter does a lot more than just trap dust. It plays a crucial role in:

✅ Improving Indoor Air Quality

Your filter traps dust, pollen, pet dander, mold spores, and other allergens that would otherwise circulate through your home.

✅ Protecting Your HVAC System

A clogged filter makes your system work harder, which can lead to higher energy bills and expensive repairs down the line.

✅ Boosting Efficiency

A clean filter helps your furnace (and AC) run more efficiently, keeping your home comfortable without wasting energy.

✅ Extending System Lifespan

Taking care of your filter can actually help your entire HVAC system last longer. Think of it as routine maintenance your wallet will thank you for later.

How Often Should You Change It?

Here’s a general rule of thumb:

  • Every 1–3 months for basic 1-inch filters

  • Every 6–12 months for thicker or high-efficiency filters

  • More often if you have pets, allergies, or a lot of dust

Pro Tip: Mark your calendar or set a reminder on your phone so you don’t forget!

How to Change Your Furnace Filter (Step-by-Step)

It’s easier than you might think:

  1. Turn off your furnace
    Safety first! Shut off the system before you remove the filter.

  2. Locate the filter
    It's usually behind a panel on the return air duct or inside the furnace itself.

  3. Check the size
    The filter size is printed on the edge (e.g., 16x25x1). Make sure your replacement matches.

  4. Slide out the old filter
    Take note of the airflow direction (usually marked with arrows).

  5. Insert the new filter
    Make sure it’s facing the correct direction. Write the date on the new filter.

  6. Turn the system back on
    That’s it! You’re done.

Changing your furnace filter is one of those small tasks that makes a big impact on your home’s air quality, comfort, and energy efficiency. Best of all, it takes less than 10 minutes!
