The IsoArk and SteriTent biological filtration units are equipped with a highly efficient HEPA filter, combined with a powerful UV light. The HEPA filter traps the airborne particulates, aerosols, and viruses, which are then destroyed by the UV light source, preventing the accumulation of living microorganisms in the system. The systems can be used in both positive and negative pressure applications in tandem with the IsoArk or SteriTent isolation tents, or can be used separately, utilizing the available infrastructure (Ebola, corona virus / .COVID-19)
