DELTRI+ filters are virucidal filters for air-handling units (AHUs) that contain advanced plasma technology capable of neutralizing or destroying 99% of all viruses, including SARS-CoV-2, as tested by the Luxembourg Institute of Science and Technology and an independent laboratory. The filters are UL and Eurovent certified. They’re available as an optional accessory item for all new or installed Systemair Geniox and Topvex air handling units, as well as replacement filters in standard sizes for existing air handling units, regardless of the brand. With DELTRI+, building owners can improve existing units before considering more extensive upgrades to their ventilation systems. The DELTRI+ filters offer a solution that is easy to apply and manage. Furthermore, for building owners and facility managers, the filters enable immediate additional safety when replaced.
