For a mask to work well, it needs to have both a good fit and good filtration:
The best mask has a high-quality filter, fits well against your face, and is comfortable enough for you to wear consistently.
* Some cloth masks are designed with specialized filter/layers and are tested to demonstrate that they perform at a consistent level. The American Society for Testing and Materials (ASTM) has set a standard (ASTM F3502-21) for barrier face coverings, including cloth ("reusable") masks. The most protective ASTM F3502-21 performance level masks have a particulate filtration efficiency of at least 95%. ASTM F3502-21 performance level ratings for some commercially available face masks are published on the CDC/NIOSH website Barrier Face Coverings and Workplace Performance/Performance Plus Masks. If you are considering purchasing a cloth mask, look for ones with high performance level (≥95% particulate filtration efficiency) and that have been tested by an accredited third-party laboratory.
