Hydroxyls are produced in abundance outdoors by the sun. These hydroxyls actively kill virus and bacteria which is why transmission outdoors is much less likely. Cubusan achieves this same process indoors using industry leading Sterex technology to produce Hydroxyl radicals. These Hydroxyl radicals are generated and then released into the air where they are free to move throughout the room. This means that all areas of the room are protected. If germs are brought into the room by someone who is infected they are destroyed as they are released into the air. This is truly ground breaking, as no other system offers the same level of real time protection.
