HEPA air filtration in HVAC

Most of the air in a home is continually recycled through its heating and cooling system. Over time that air becomes stale and full of pollutants unless there’s an indoor air quality system. An HVAC professional can help you select the best method for air purification, but one option is to install a HEPA air filter in your system.



What it is

HEPA stands for High Efficiency Particulate Arresting. It refers to a type of filter that has been manufactured, tested, certified to remove 99.7% of all particles greater than 0.3 microns (or millionth of a meter). To give some scale, a human blood cell is 5 microns wide – so 0.3 microns would be less than 1/15th of that size. Understandably, these filters are top of the line for air filtration.


How it works

When air is forced through a HEPA filter, airborne particles get trapped in dense, randomly arranged fibrous mat.

HEPA-like filters are commonly used in vacuums to remove dust and allergens from carpets and other types of flooring. However, the HEPA filtration products that are installed in HVAC systems are stringent enough to remove not only dust but many of those unhealthy microbes that float around in the air during cold and flu season.


What it does

A HEPA filtration system will reduce the allergens and other airborne respiratory triggers that circulate throughout your home. Certified HEPA filters are efficient enough to capture:

-Mold spores
-Pet dander
-Chemicals from cleaners

Benefits of HEPA Filtration

Because these first-class air filters are so efficient at removing the majority of air contaminants, they’re commonly used in hospitals and science labs.

Even in your own home , using a HEPA purifier to filter the air can be a health benefit to everyone living there and help with several conditions, including:

  • Respiratory problems
  • Asthma attacks
  • Congestion and runny nose
  • Hay fever
  • Headaches, dizziness, or nausea caused by odors
