Nanosonics founder Maurie Stang is back in the disinfection game, but this time he’s focused on helping companies create safer working environments by purifying air to reduce the risk of germs spreading.

Mr Stang, who was also chairman of the ASX-listed, $1 billion disinfection device company until July this year, has formed a joint venture between his business Gryphon Capital and local air detoxification start-up VBreathe.
