Bernie Erickson of Facilities Solutions Group is in the middle of expanding his company's offerings in UV disinfection options, so we had to ask him on the show to share what he’s been working on.He breaks down the differences between surface and air disinfection as he sells it, as well pointing out secondary gains from adding air purification. What he has noticed is that his customers seem to have their own phases for adoption of UV purification moving from portable units to more permanent installations. He also offers some advice on how to sort junk products from good ones in this sudden boom in the market.Beyond that we offer a diversion on controls, ‘hygiene theater’, and tips for introducing the technology to new clients.
