When you purchase the industry-leading Evolution™ Extreme 26 air conditioner or Evolution™ Extreme 24 heat pump, we’ll include an Evolution™ air purifier. (Limited time offer. Terms apply. See your participating dealer for details.) The Evolution air purifier works silently in-line with the HVAC system and can improve indoor air quality. With every cycle of air that passes through this patented air purifying system, pollen, animal dander, bacteria and other pollutants are trapped and held tightly to the filter. An electrical charge then bursts the cell walls of pathogens it comes in contact with. Learn more: https://www.bryant.com/en/us/products/air-purifiers/dgapa/
