Ohio Gov. Mike DeWine criticized the FDA for issuing limited approval for the technology Saturday. But at a press conference Sunday, DeWine said the FDA's commissioner, Steve Hahn, told him "this would be cleared up today."
"Thank you Dr. Hahn [and] the FDA for your fast approval of this respected Ohio company recommended by Governor Mike DeWine. Great potential!" Trump wrote on Twitter on Monday morning.
Battelle said it could decontaminate 80,000 N95 respirators per day with its Critical Care Decontamination System in West Jefferson, Ohio.
"I want to thank the FDA team for their professionalism and help in authorizing the use of our technology at this critical moment for our nation," Lou Von Thaer, president and CEO of Battelle, said in a statement. "Everybody who has worked on this project shares the same goal of protecting first responders and healthcare workers who are at the front lines of the pandemic."
Battelle has previously said it is rapidly manufacturing more Critical Care Decontamination Systems to be deployed to needy hospitals across the country.
Hospitals are desperate for personal protective equipment for their workers on the front lines of the coronavirus pandemic response.
Battelle's method is the same as one confirmed last week by Duke Health, which found that N-95 masks can be safely reused after being decontaminated with vapor phase hydrogen peroxide.
Duke Health's process takes about four to five hours and involves hanging the masks in a room to be sprayed with the aerosol.
"This is intended to conserve a critical resource, which is our people who support the entire health care process," Dr. Wayne Thomann of Duke University School of Medicine told FOX Business Thursday.
