Cirqulair is a patented technology for cleaning the air. It is scalable from a small unit to clean the air in a one-bedroom apartment, up to units that are installed within an HVAC system of a large office building or hotel. Cirqulair is special because it's the only known way to clean the air of all particles as small as 3 nanometers.
