Different HVAC Filters and How They Work

As technology continues to evolve, filters have become more sophisticated and proficient at cleaning your air. Here are the top HVAC filters available, how they work, and what to expect if you don’t replace them in time.

Fiberglass

The cheapest and most prevalent filter option on the market is fiberglass. These filters are disposable, making replacement easy enough that anyone can do it. Newer filters are better at trapping dust and harmful particles, fiberglass filters are more accessible.

Washable Filters

If you want to spend extra money to save replacements, washable air filters are a great option. Directions vary, but you can wash these filters frequently and have clean air on demand. Be sure to let them dry long enough, as mold and bacteria can quickly grow if they’re left damp.

Pleated Filters

Pleated filters are usually made from cotton or polyester. The more pleats you have, the better your filtration will be. Pleated filters are some of the best on the market at trapping dust and pollutants, making them an excellent option for someone with a respiratory condition.

HEPA

Experts also recommend HEPA filters for people with allergies or breathing conditions. High-efficiency particulate air filters, or HEPA, can catch over 99% of particulates in the air, creating a safer breathing environment for all.

Electrostatic

As the name implies, these filters use a static charge to catch dirt and other particles in your air. Some electrostatic filters are washable, making them a versatile option for many households. Allergy sufferers often rely on these filters because they stop pollen and other allergens before they can enter your air system.

UV

One emerging technology is UV filters. These filters use UV light to neutralize bacteria and viruses in your home. There’s been a greater focus on UV filters since the start of the pandemic, and they are a great buy to keep your air safe.

Why Frequent Replacement or Cleaning Is Important

Ignoring your home’s filtration system can have many adverse effects on the health of your system—and your health. Make sure to dry out washable filters completely before reinstalling them to prevent mold and bacteria growth.

Regular replacements or cleaning can also keep harmful particles from entering your air. Dirty filters can only hold so much, and if you don’t wash or replace them, you could be spewing everything that’s trapped back into your home. Dirty filters also make your HVAC system work harder, causing breakdowns or repairs due to inefficient operation. Be sure to replace or wash your filters regularly to avoid any adverse side effects.

With a solid routine and preventative maintenance, you can keep your HVAC system operating like new. And if something comes up that seems too big for a DIY project, hit up the pros at Doctor Fix-It. With their knowledge and expertise, they’ll keep you comfortable no matter the season.
