Not sure who GOODWAY are personally I have more faith in Boeing who obviously work in a highly regulated sector.
Boeing says "These HEPA filters, which are similar to those used in hospital operating rooms and industrial clean rooms, trap more than 99.9% of particulates such as bacteria and viruses from the air before it is recirculated to the cabin."
Current on Boeing website today.
No mask business worth a damn and no air filtration business anytime soon either.
