Retrofit Magazine shared the news that Trane will now sell the enVerid Air Purifier as part of its Wellsphere portfolio of air cleaning solutions. According to the article:
“Ceiling-mounted HEPA filtration units are preferred by IAQ experts for COVID-19 transmission mitigation for a number of reasons, most importantly because they maximize air flow given their unobstructed location and optimized placement in the center of a room and because they are quieter to operate than most portable units.”
“With respect to air cleaners for airborne pathogens, there is a very clear hierarchy of performance,” said Raefer Wallis, global indoor air quality expert and Founder of RESET. “At the very top, we find ceiling-mounted filtration systems that allow for a very high level of control in specific areas because they are ducted and unobstructed by objects in a room. This is extremely important for issues like COVID-19, where aerosolized viruses can be reduced at the source. The next level down is portable filters, which can be 20-50 percent less effective than their ceiling mounted counterparts mainly due to challenges with placement in a space.”
