Hygiene has a high priority in, for example, the food industry as impure air negatively affects the quality of products. By applying ionization to a ventilation system, viruses, fungi, and bacteria are combated. With Oxycom's technology, the air in a room is ventilated several times an hour with fresh, well-filtered outside air. However, it is possible that there are still viruses present in the room, carried in by the people on-site, for example. Ionization eliminates 99.5% of these viruses, so there is no chance of them spreading through the air.
