The Importance of a Clean Air Filter

Your furnace air filter acts as a barrier, trapping dust, pollen, pet dander, and other airborne particles before they can circulate through your home. A clogged or dirty filter forces your HVAC system to work harder, reducing its efficiency and lifespan. This not only leads to higher energy bills, but it can also compromise the air quality in your home, exacerbating allergies and respiratory issues for you and your family.

When to Replace Your Furnace Air Filter

The general rule of thumb is to replace your furnace air filter every 3 to 6 months, or as recommended by the manufacturer. However, this timeline can vary depending on a few key factors:

Household Size and Activity

The more people and pets in your home, the faster your air filter will become dirty. If you have a large family or furry friends, you may need to replace the filter more frequently.

Filter Type

Some filters are designed to last longer than others. Pleated filters, for example, typically have a longer lifespan than basic fiberglass filters.

HVAC Usage

If you run your furnace or air conditioning unit constantly, your filter will become clogged more quickly than if you use it intermittently.

Time of Year

During peak heating and cooling seasons, your filter will likely need to be changed more often as it works harder to keep up with the increased HVAC usage.

How to Replace Your Furnace Air Filter

Replacing your furnace air filter is a simple task that can be done in just a few minutes. First, locate the filter, which is usually found in the return air duct or the furnace itself. Carefully remove the old filter and note the size and orientation, then insert the new filter, making sure it fits snugly. Be sure to dispose of the old filter properly.
