Confined Plasma Filtration

Aireshield® works by creating a non-thermal, confined plasma field between a central electrode pin (positive) and a downstream circular grid (negative). As air passes through this field, airborne pathogens such as viruses and bacteria are exposed to a controlled electrical charge that disrupts their structure. In viruses, the plasma induces electroporation that ruptures their lipid membranes, while in bacteria it compromises the cell walls, exposing genetic material to atmospheric oxygen and rendering them non-viable. At the same time, the bipolar ions within the plasma field cause fine airborne particles to agglomerate, making them large enough to be captured by the existing HVAC filter. The process is fully contained within the module and does not emit ozone, ions, or any other by-products—ensuring clean, safe air throughout the system.
