Ying Zhong of USF has discovered a way to rapidly disinfect and electrostatically recharge disposable N95 masks, restoring them to their original filtration effectiveness. The technology employs atmospheric pressure plasma that uses no extra heat or chemicals, making it more cost-effective and convenient for use.

“It is a reduction of 90 percent for each user. If we assume that 10 percent of the population all over the world takes advantage of corona discharge mask reuse technology, there will be four- five billion fewer masks disposed,” said Zhong. “It will reduce at least 24 million tons of plastic pollution.
