Air purification systems are pieces of equipment that are designed to dramatically improve indoor air quality both by removing contaminants and neutralizing microscopic biological organisms. These systems work by purifying the air that is being supplied to your HVAC system through your return register. Depending on the product, some are mounted in this return duct, while others are mounted in your indoor HVAC unit itself. Most of these products require little to no maintenance and very little additional energy, meaning they add almost no cost to operating your air conditioner or heater.

Air purification systems can remove all of the following:

​

• Odors & odor particles

• Dust

• Pet dander

• Pollen

• Bacteria & viruses

• VOCs

• Mold spores

Of all of the indoor air quality improvements you can buy, air purifiers are typically the most expensive. This is because not only are they the most technologically advanced, but they are also some of the only types of air quality improvement systems that can specifically target and eliminate both biological and non-biological airborne contaminants. They are also adept at capturing and eliminating even some of the absolute smallest air pollutants you might encounter—pollutants that an average air filter either struggles with or is completely incapable of capturing.
