As temperatures drop in Northeast Ohio, your furnace works overtime to keep your home warm. But did you know that a clogged furnace filter can reduce efficiency, increase energy costs, and lower indoor air quality? Regularly replacing your furnace filter in the winter is a simple yet crucial step in maintaining a healthy and efficient heating system.

How Often Should You Change Your Furnace Filter?

The frequency of furnace filter replacement depends on several factors, including the type of filter, household conditions, and how often your furnace runs. Here’s a general guideline:

• Basic fiberglass filters: Replace every 30 days
• Pleated filters (standard efficiency): Replace every 60–90 days
• High-efficiency HEPA filters: Replace every 6–12 months
• Homes with pets, allergies, or smokers: Replace every 30–60 days
• Heavy furnace usage (cold months): Check monthly and replace as needed

Since furnaces run more frequently in winter, checking your filter once a month is a good habit to prevent airflow restrictions and efficiency loss.

Why Replacing Your Furnace Filter Matters

1. Improves Energy Efficiency

A dirty filter makes your furnace work harder to push air through your home, leading to higher energy consumption. A clean filter helps maintain proper airflow, reducing strain on the system and lowering your heating bills.

2. Enhances Indoor Air Quality

During winter, windows stay shut, and indoor air can become stale. A fresh filter helps trap dust, allergens, and airborne pollutants, improving the air you breathe.

3. Extends Furnace Lifespan

Restricted airflow due to a clogged filter can cause your furnace to overheat, leading to unnecessary wear and tear. Regular replacements help your HVAC system run smoothly and last longer.

4. Prevents Breakdowns

A neglected filter can cause overheating, cycling issues, and even a furnace shutdown. Regular replacements reduce the risk of mid-winter malfunctions, ensuring reliable heating when you need it most.

How to Change Your Furnace Filter

Replacing your furnace filter is a simple task that takes just a few minutes:

1. Turn off your furnace to ensure safety.
2. Locate the filter – typically found in the return air duct or inside the furnace cabinet.
3. Check the size (printed on the existing filter) and purchase a replacement.
4. Remove the old filter and dispose of it properly.
5. Insert the new filter, ensuring the airflow arrow points toward the furnace.
6. Turn your furnace back on and enjoy improved air quality and efficiency.
