4 Reasons You Need to Keep Your Air Filter Clean

keep your air filter clean

It can be hard to remember to keep your air filter clean. It’s one of those “out of sight, out of mind” home maintenance chores. And some new homeowners aren’t even aware that air filters need changing regularly.

If you have a heating and cooling unit, your air filter is vital. And you need to keep it clean – even if you need to write a note on your calendar to remind yourself. Here’s why:

You Need to Keep Your Air Filter Clean To:

1. Maximize Efficiency

Your heating and cooling system recycles the air in your home for greater efficiency. It draws the air out through the cold air return. Once the air reaches the unit, it passes over coils to heat or cool it. Then, it heads back to the house through your ducts.

An air filter catches dust and other airborne foreign particles. This stops them from coating the coils and making heat/cold transfer less efficient.

2. Promote Cleanliness

Not only does your filter keep your heating and cooling system clean, but it also helps keep your whole house clean. It helps to stop dust buildup in ducts and keeps it from getting blown all over the house.

3. Stay Healthy

Did you know your filter isn’t just a dust barrier? Many people with allergies find them lessened once they start keeping their filter clean. That’s because it can even remove tiny particles from the air. Pet dander, pollen, pet dander, bacteria, mold spores, and even smoke can find their final resting place in your filter.

The cleaner the filter, the better it cleans the air. And cleaner air likely leads to better health.

4. Save Money

Spend a few bucks to change the filter: save more than you spend. A clogged filter makes it harder for your heating and cooling system to draw in air. It jacks up your utility bill by making your unit run for a higher percentage of the day.

How Often Should You Change Your Filter?

Now that you know what you’re missing by keeping a dirty filter, how do you know when to change it?

Some would say 3 months. And they’d technically be right.

But we recommend that you check it every month, and change it if it’s dirty. You’ll know “dirty” when you see it. Don’t wait until it’s absolutely clogged or you’ll end up negating the benefit of having a filter for weeks at a time.

If you have pets or high traffic near the filter, you’ll probably end up changing it once a month. As well you should, if it’s dirty!

You should be able to find your air filter easily. Some systems locate the filter in the unit itself, but most place the filter at the cold air return inside the home.
