Sizing an Air Filter: Why It Matters More than You Think

One of the most important things you can do for your AC system is to change the air filter. It may seem like a small, unimportant part, and many homeowners go a long period of time without ever changing or cleaning theirs. What most people don’t realize, however, is that waiting too long to change the filter can result in a number of consequences, including higher monthly bills and a lower overall lifespan for your AC system.

Another common misconception is that, in order to be healthy throughout the season, you should go for the strongest, most effective filter you can find on the shelves. Unfortunately, this typically does more harm than good.

How a Clogged Air Filter Hurts Your System

The reason you change your air filter every month or so is due to the damage that blockage can cause. This is not just for your health—though it is of concern when clogging blocks air filtration. Another major concern is the performance of your AC system

Dirt and debris in the air filter, even a small amount, can block airflow to the AC system. Since your air conditioner was designed to take in a certain amount of air and cool it, any drop in airflow can mean significant damage for the air conditioning unit.

How an Incorrectly Sized Filter Hurts Your System

Improper sizing causes trouble for an AC system in much the same way that a clogged filter does. If you choose the strongest filter available, the first concern is that it won’t fit at all. But even if it does fit in the spot provided, it might be too effective for the space in your home.

Your filter may be so strong that it blocks not just particles, but also the air in your home. You won’t get sufficient airflow to your home if this happens, and you might end up with higher energy bills and a broken AC system.

Check with a technician before purchasing a different filter. And if you want better air filtration, see a technician about installing a whole-home air filtration system.
