Your A/C is composed of numerous parts – all of which have an important role. One crucial piece is its filter. Below you’ll find more information about how it works and the different types available.

How Does an A/C Filter Work?

When your HVAC turns on it works alongside your A/C. As it does so, it will start breathing in and blowing out air through its filter. This device will help trap any allergens and other particles that could otherwise cause poor air quality.

When you go to replace the filter, you’ll notice that this once clean gadget now has layers of dust-like debris on it. While a bit unsightly, it’s a sign that the filter is working.

The Types of A/C Filters

  • Fiberglass: A fiberglass filter is one of the most affordable and syncs well with HVAC systems. While its fibers trap most particles, minuscule ones can sometimes slip through.
  • HEPA: This filter is best for those who want to prevent even the smallest of particles from getting mixed into the air. HEPA filters are ideal for those who suffer from allergies because they contain different layers that the air must pass through. This way, it can capture most debris. However, they can sometimes be a bit tricky to use with HVACs because they can overwhelm the system’s motor.
  • UV: Ultraviolet filters use UV light to destroy harmful allergens and bacteria. Thanks to this feature, it keeps them from escaping into your home. Keep in mind though that because of this unique technology they can be pricey but they’ll last you for a while.
  • Pleated: This selection is the most common and is made up of multiple cotton folds. This design helps them trap air debris. The more pleats built into the filter, the better job it will do. While simple, they’re extremely durable and tend to last longer than other options.

When Should I Replace the Filter?

Ideally, with regular use, change the filter every three months. This will ensure that the piece keeps functioning correctly and doesn’t get clogged. However, if you suffer from allergies, replacing it each month might be best.
