Disinfection & odor reduction using an innovative plasma technology

Our Cubusan air purifier reduces the germ load in enclosed spaces to a minimum. As a unique, decentralized disinfection technology, indoor air disinfection with Cubusan is also sustained and direct. This means that harmful bacteria and viruses are directly neutralized at the source at any time. The air purifier is a sustainable investment in your health and efficient protection for you and the people around you. 

How does the Cubusan air purifier work?

The Cubusan air purifier from WINTERSTEIGER is based on the innovative Sterex plasma technology and was especially developed for indoor air disinfection. The atmospheric low-pressure plasma neutralizes 99.9 percent of viruses and bacteria in the air, reducing the risk of infection to a minimum. While conventional air purifiers recirculate all the indoor air first in order to then gradually remove germs via filtration, the Cubusan air purifier eliminates the harmful particles directly at source – where they enter the air as aerosols. The system therefore ensures a sustained reduction in infections. 

The conditions: To ensure maximum removal of germs, the Cubusan air purifiers should be activated around an hour before a room is used. This is the only way to fully disinfect an area of 70 to 120 m3 in advance and maintain the level of purity while several people are present.

Good to know: The Cubusan air purifier is extremely quiet, requires no maintenance or upkeep, and works without ozone or UV-C treatment.
