This in vitro study demonstrated the efficacy of the Defend 400 device at removing aerosolized Micrococcus luteus bacteria. The Defend 400 device is designed to reduce airborne bacteria, viruses and fungal spores in order to decrease infection rates from airborne pathogens.
Micrococcus luteus was aerosolized into a 58.8m3 room containing the NV400 for evaluation. The Defend 400 was evaluated at fan speed 5 and Air samples were taken every 5 or 10 minutes depending on the test in order to quantify the reduction capabilities of the device at maximum speed. Control trial data was subtracted from the Defend 400 trial data to yield net LOG reduction for bioaerosol reductions. An external company was used to count samples to ensure the
results were blinded.
The Defend 400 had an average bacterial reduction of 97.7% (1.64 log) in 60 minutes in a 58.8m3 room.
