Speed. Room Temperature Test | |
|-----------|---------------------------------------------------------------------------|-------------------|
| Bacteria | Bacillus atrophaeus | 4.95 / 60 minutes |
| Bacteria | Bacillus atrophaeus | 4.00 / 48 minutes |
| Mold | Penicillium rocqueforti | 4.40 / 60 minutes |
| Mold | Penicillium rocqueforti | 4.00 / 52 minutes |
| Virus | MS-2 bacteriophage | 5.32 / 60 minutes |
| Virus | MS-2 bacteriophage | 4.00 / 40 minutes |
The Bluezone Model RX-450 is an air purification device that uses germicidal UV bulbs to inactivate viral, bacterial or fungal aerosols. The operation of the device is as follows: ambient air containing microbial aerosols is drawn into the air purifier through a prefilter and two angled aluminum honeycomb light baffles. The infective aerosols in the air are then exposed to high intensity, germicidal, ultraviolet light where the contaminants receive a UV dose of at least 10 mW*second/cm². The bacterial, fungal and viral aerosols are inactivated through the breakdown of the microbial DNA or RNA. The cleaned air is exhausted back into the room from the Bluezone Model RX-450 through an axial fan.
