Whether you are from the dental, aesthetic or food industry, infection protection is the basis of your daily work. Before putting on your mask, are you able to properly identify the protection you need? Maybe this little description will help.
All our masks follow the standards prescribed by ASTM, the American Society for Testing and Equipment. Like ISO, ASTM is a standards body that has been writing technical standards for materials since 1898. Born of a need for standardization in the railway industry, ASTM now has more than twelve thousand standards in its catalogue.
For procedural masks, the standard consists of three levels; ASTM 1, 2 and 3. Each level classifies materials according to their resistance to liquid (calculated in mmHG) and the rate of filtered bacteria, the famous BFE ( Filtration Efficiency Bacteria ). You must, therefore, adapt your choice of protection to your use, for example, ASTM 1 is perfect for a dental cleaning but does not offer sufficient protection when it comes to surgery where a ASTM 3 is needed.
In closing, do not forget to change your mask after each patient or after more than one hour of use to ensure maximum protection.
