Works great! Have figured out with this equipment the old, disgusting moldy-musty smell from a long time too little heated and possibly never properly ventilated apartment. The following procedure using the example of a 54 cubic meter room: - Treat the enclosed space 12 hours - Ventilate complete 30 minutes The whole thing was indeed a total of 6 times necessary. After each treatment, the smell was a bit better, but then came yet again (always weaker) by. Have all pulled more consistently. The stale air is now completely gone! To check the space closed 24 hour - no smell more! Important to know: After the 12 Hours of the smell in the closed space very strongly of ozone. The device is in my opinion for the simultaneous permanent residence (especially in enclosed spaces) too. So I would not use the machine in presence. For the above or similar purposes but highly recommended!
