Here is a side-by-side quick comparison of US mask standards and EU’s counterpart.
General applications for ASTM-rated masks:
- ASTM LEVEL 1: General public and healthcare where there is no or low liquid splash present.
- ASTM LEVEL 2: Healthcare where there is medium level of liquid splash present.
- ASTM LEVEL 3: Healthcare & surgical where there is a high level of liquid splash present.
An Important tip for the general public: use ASTM Level 1 masks when you can buy, instead of non-medical masks for better protection
