Biological Agents such as Allergens and Pathogens?
Pollens, molds, viruses, bacteria and other biological agents are particles that obey the same properties of aerosol physics as do non-biological particles. Airborne biological agents can be filtered by FFPR’s with the same efficiency as are the non-biological particles. Unlike with industrial hazards however, there are no established exposure limits (PEL) for biological agents. The Fitsealâ„¢ respirators will definitely reduce, per its NIOSH rating, the wearer’s inhalation of the harmful particles, but not to absolute zero. The Fitsealâ„¢ respirators significantly reduce exposure, but do not eliminate all risks of infection. The Fitsealâ„¢ respirator was conceived during the SARS outbreaks, and was designed with infectious diseases in mind.
