Breathe easier with a Carrier^® Infinity^® or Performance™ air purifier with patented Captures and Kills™ technology. An Infinity air purifier can capture up to 95% of particles as small as .30 micron from the air passing through your HVAC system. Both are proven effective against human influenza, common cold viruses and strep. Carrier air purifiers are designed to work in line with your home’s ductwork. So for about the same cost as a couple of high-end, single-room air purifiers, you could have clean air for your whole house.
