The M1 main filter is a high-efficiency filtration module designed specifically for the Acu-Evac surgical evacuation system. It combines activated charcoal for odour control with a ULPA (ultra low penetration air) filter, delivering a powerful defence against noxious gases and ultra-fine particles encountered during surgical procedures. 

Engineered for exceptional performance, the ULPA filter captures 999% of particles in the range of 0.01 to 0.12 microns, effectively neutralising ultra fine contaminants that standard filters may miss.

With filter life up to 16 hours, the M1 is optimised for extended use during demanding procedures, while maintaining peak filtration efficiency throughout its lifespan.
