As research increasingly indicates that airborne transmission of Covid-19 is a threat, improving indoor air quality has become a priority for many hoteliers.
"Air is a big part of the challenge," said infectious diseases specialist and epidemiologist Dr. Ravina Kullar. "If you're indoors, you might be cleaning the surfaces well, but if the virus is still lingering in the air, then that's a problem. A lot of hotel rooms have older air filtration systems that just circulate in and out, so they're having to think about ways to upgrade their air filtration systems."
