Infinity air purifier works silently in-line with your HVAC system and can make the air you breathe healthier. It uses Captures & Kills™ technology to trap up to 95% of particles1, then uses an electrical charge to kill or inactive them. Independent testing has proven the Infinity air purifier's effectiveness against 3 pathogens including the common cold surrogate. With every cycle of air that passes through this patented air purifying system, pollen, animal dander, smoke, 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.
