A simple dinner conversation between a husband and wife could potentially have resulted in a game-changing idea for disinfecting and reusing N95 masks.
In March 2020, Laurie and Kevin Hommema had just finished a family dinner with their two daughters at their home in Columbus, Ohio. Kevin is an engineer and wife Laurie is a family physician. During their conversation the couple used their combined knowledge to come up with a system that would allow much needed N95 masks to be decontaminated for reuse.
Their system involves using concentrated hydrogen peroxide vapor inside of a chamber- in this case, a re-purposed shipping container, where the masks are decontaminated after about 2.5 hours.
By running the disinfection container, it was capable of processing as many as 80,000 N95 masks in a single day. The system is so effective, the process can be repeated on the same mask up to 20 times without it degrading.
This is happening right now at our West Jefferson #BattelleCCDS facility. These #N95 masks have been decontaminated and are now drying for delivery to Ohio hospitals soon. #itcanbedone pic.twitter.com/dpAxuCOsPM
