MFC PM2.5 Filter Face Mask - Protect yourself and others with these stylish filter masks.
A fitted face mask with a PM2.5 filter offers a high degree of filtration from particulates and aerosols. PM 2.5 refers to these filters' original use as protection against micro-particulates, although they are capable of filtering much smaller particles. Fine aerosols that may harbor viruses are typically measured in nanometers and laboratory testing shows a PM2.5 filter with a properly-fitted cloth mask reduces airborne particulates by as much as 90%.
