To guarantee indoor air quality and durability of purifiers, we use centrifugal fan and medical grade HEPA to purify indoor air and remove particulate matters. UVC and plasma techniques are also used to deactivate microoganisms that may cause infection in hospitals and other facilities. Other effective techniques like activated carbon, PCO, are also employed as required. Our purifiers with high flow and efficient disinfection can be used in offices, classrooms, hospitals, homes.
