• It eliminates 99.9% of bacteria and viruses from the air or any surfaces. 
• It eliminates any bad smells, leaving your surroundings odourless.
• Reduces PM1, PM5 and PM10 particles that can be found in the air. 
• Reduces Volatile Organic Compounds (VOCs) 
• Reduces potential allergens. 

Yes, depending on the pathogen and humidity levels, around 60% of pathogens could be eliminated in about 10-12 minutes.  

Yes, if there is good air circulation between the consultation rooms, i.e. doors are open and the air can flow from room to room, one unit could be sufficient. 

However, in order to guarantee that all consultation rooms are disinfected effectively, ideally, you would need one unit in each room. 

This would depend on the outside air quality. If this air is dirty and full of pollutants (for example, city air), this is not advisable, as although it could help to remove possible pathogens that may be brought in by the patient, it would also let in a large amount of pollutants that are present in the outside air.
On the other hand, if the outside air is largely free from pollutants, we do recommend opening windows, as this would help to ventilate the consultation room and disseminate the purifying effect. 

No, the chain reaction won't last very long after the unit has been turned off. The average lifespan of a Hydroxyl Radical is 100 picoseconds, meaning that the reaction would need to be maintained from the very beginning, as it gradually declines due to the inactivation of the pathogens themselves until there are none left. 

No, the electrical charge of a Hydroxyl Radical emitted by the Wellisair is neutral, which means that it won't react with any materials other than pathogens.
