As the simulation in the video shows, aerosols rise up and spread throughout the room within 120-140 sec and descend.

Here the design of the air purification lamp, above the source of origin acts to reduce aerosol dispersion in enclosed spaces.

The positioning of the dp-Purifier lamp in the room under the ceiling about 2.5 m above the floor, attracts dp-Purifier lamp aerosols and fine dust particles (suspended range of particles in the air) above the source of origin (ie occupied zone and breathing height) and flows out the purified air in 360 °, above the air purifier lamp.
