We used 8 air purifiers in the entertainment business, here in Miami FL. For the Latin Grammys 2020. At the American Airlines Arena in mid-november we placed 6 air purifiers rigged from the roof over the stage. 3 on either side and 2 more air purifiers back stage where we have heavy traffic of stage hands and stage managers. Trying to keep the industry alive, the air purifiers are another layer of security to keep air clean and clear of the COVID 19 virus or any other virus. They have become very popular in our network as other departments keep recuesting them, but we continue to use them in different entertainment shows, televised award shows and other TV shows.
