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 particles, 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 all pollutants are trapped and held tightly to the filter.
