How a Whole-Home Air Filtration System Works


If you have a household member with allergies, asthma, or other breathing sensitivities, you already know the importance of clean, filtered air in your home. However, did you know that everyone in your home can actually benefit from a whole-home air filtration system? These ingenious devices can reduce particulate, bacteria, and germ matter in your home—stuff you may not even know is in the air—by up to 99.97%, making for safer and healthier air quality in the home. Here’s how they work.

Duct-Mounted Convenience

A whole-home air filtration system might seem like it would be a massive undertaking, but it’s just the opposite. These systems take advantage of the ducts that already exist throughout your home for heating, cooling, and air circulation. The filtration device will be installed near your existing heating and cooling systems and will use the same infrastructure already in place to access airflow to your whole house, making it an affordable option for most homes.

HEPA-Certified Filters

A high-efficiency particulate air filter, or HEPA filter, is a kind of pleated mechanical filter with holes fine enough to capture particles in the air down to 0.03 microns in size. For comparison, that’s about 1,500 times smaller than a single human hair. Your whole-home filtration system, if equipped with HEPA filters, can capture dust, dust mites, hair, pollen, pet dander, skin flakes, mold, and even some forms of bacteria. This can help your whole family breathe easier. If your budget is holding you back from clean quality air for your family, ask your HVAC contractor if they offer financing options.

Germicidal Technology

Ultraviolet light has long been known to have germicidal properties. Many air filtration systems have taken advantage of this quality by including ultraviolet-C, or UVC, light bulbs in order to kill potentially illness-causing germs and bacteria in the air. Your whole-home filtration system is no different and may be equipped with several bulbs to offer comprehensive protection against microscopic health threats. Your system may also be equipped with photocatalytic oxidization technology, which uses a combination of UV light and coated metal plates to destroy the molecular bonds in odour-causing, bioactive, and volatile organic compounds. A qualified contractor will be able to help you make the right decision regarding which option is best for your home.

Extra Efficiency

Your whole-home air purification system can save you time, money, and hassle. By centralizing air filtration, your system reduces or eliminates the need to buy and replace separate HVAC filters. You also save money and energy when compared to single-room air filtration units, which do not cover as much area, are bulky and often unsightly, and draw additionally on your electric grid, increasing your bills. They also create little to no extra noise when used in conjunction with your existing HVAC systems.
