The NV200 unit was placed inside a 68 litre plastic enclosure. The plastic enclosure and test set up was placed inside a biosafety cabinet. Clinical isolate of Mycobacterium tuberculosis was aseptically transferred into a sterile mycobacteria growth indicator tube (MGIT) and Lowenstein-Jensen (LJ) medium.
The air sample collected from the test after being exposed to the NV200 showed no growth of Mycobacterium tuberculosis. This shows that the device has effectively rendered all airborne Mycobacterium tuberculosis non-viable.
