Particle resuspension

The concern about the effects of particle exposure on our health has increased the attention on particle deposition and directly on resuspension in indoor environments.
They can be inhaled by the human respiratory system.
These particles have been identified as a major airborne contaminant source. 
How can we reduce uncertainty in large-scale aerosol models?
I painted an abstract model that has the potential to be an alternative choice to improve indoor air quality.
