FFP1, the most basic, is often used for DIY tasks such as sanding. It offers protection against non-toxic substances such as pollen, limestone cement and brick dust.
FFP2, or n95 masks provide greater protection than FFP1 and is recommended during outbreaks of SARS, coronavirus and avian flu. It also protects against deleterious substances such as smoke, aerosols and lead dust. FFP2 masks are popular in metal, mining, agricultural industries, as well as healthcare workers to protect from influenza.
FFP3, the highest level of protection when exposed to environmental hazardous substances. FFP3 protects against viruses, bacteria, asbestos and other toxins. It is also used for handling hazardous pharmaceutical chemicals by healthcare professionals.
