Air Sterilization for many environments including work, home, and restaurants

Experts lay out the need and requirements for a safe environment:

“So the air in your home probably changes over once every hour or two hours,” says Linsey Marr, a Virginia Tech engineer who studies the airborne spread of viruses. “We’re aiming for an air exchange rate of, like, six per hour.” That recommendation, she says, comes from studies of tuberculosis transmission. (Tuberculosis is not SARS-CoV-2. TB is much more contagious and is thought to be able to spread farther and stay longer in the air.)”

She adds that, “you also need to be careful when changing the filters because they could be contaminated with virus.”

“Air filters have to be constantly running to work” Jeffrey Seigel, air filtration expert at the University of Toronto.”…air cleaning needs to be continuous in the spaces we inhabit. As long as there are living, breathing people in a space, we’re potentially contaminating it with virus.”

“If you look at air cleaning products, you’ll find a lot of gimmicks: ionizers, plasma generators that claim to amp up the power of filters. “There’s very little science behind them,” Siegel says. “It’s not only that the devices are ineffective and maybe lull people into a false sense of security, but in some cases they’re actually harmful.”

“There’s yet another option for removing virus from the air: killing it with ultraviolet lamps. That said, Eleanor Miller, Sc.D., Boston University epidemiologist — who specializes in studying devices that do this sort of thing — doesn’t recommend these for the average consumer.”
