The Self-Assembly Filtration for Emergencies (S.A.F.E) Cartridge System is a modular HEPA filtration system that can be fitted onto hospital masks such as the disposable AeroEclipse Aerosol Mask made by Monaghan Medical Corporation. The S.A.F.E Cartridge System can also be fitted onto 3D printed masks while maintaining functionality. Conducted by a certified technician, the S.A.F.E. Cartridge System and masks were tested for fit and filtration efficacy utilizing the same test procedure and compound as used in standard N95 fit tests. The prototypes were deemed effective.
