Bryant® Evolution™ Whole Home Air Purifier Helps Eliminate Coronavirus in Filtered Air

University of Colorado testing finds Captures & Kills® technology inactivates 99% of coronavirus trapped on the filter; also kills flu and common cold viruses

INDIANAPOLIS, Oct. 6, 2020 – Testing by the University of Colorado Department of Civil, Environmental and Architectural Engineering found that the Bryant Evolution air purifier with Captures & Kills technology inactivates 99% of coronavirus trapped on the filter. Other third-party testing has concluded that this technology also inactivates 99% of select viruses and bacteria trapped on the filter, such as a common cold virus surrogate, Streptococcus pyogenes and human influenza. Bryant, a leading supplier of heating, ventilating, and air conditioning (HVAC) equipment, is a part of Carrier Global Corporation (NYSE: CARR), a leading global provider of healthy, safe and sustainable building and cold chain solutions.

The Evolution air purifier works silently as part of a home heating and cooling system, using a filter and electrical charges to inactivate various pathogens, pollen, animal dander and other contaminants to enhance indoor air quality.

“As people continue to spend more time at home, it’s important to have technology to help make indoor environments healthier and safer,” said Justin Keppy, President, NA Residential & Light Commercial, Carrier. “By removing these pathogens, including coronavirus, from the air it filters, the Evolution air purifier gives families peace of mind that their loved ones have a cleaner and healthier home in which to live, learn, work and play.”

The Evolution air purifier works with most HVAC systems produced by both Bryant and other manufacturers and treats the air flowing through an HVAC system’s air handler using a three-step, charge/capture/kill process that inactivates 99% of select viruses and bacteria:

  • Step One: Charge – the purifier creates a “cloud” of electrically charged ions that attach themselves to airborne dust, pollen, viruses, germs and other particles as they pass through.
  • Step Two: Capture – the ionized particles are pulled toward an oppositely charged, pleated filter and captured at an extremely high rate.
  • Step Three: Kill – captured airborne microbes remain on the pleated filter instead of recirculating back into the home and are subjected to an intense electric field.

The University of Colorado’s testing was conducted with a murine coronavirus that is closely related to the human coronavirus SARS-CoV-2, which causes COVID-19. The murine pathogen surrogate allowed testing to be completed safely.
