The TNT Filter is a protective filter worn conjointly with the Cochic mask to add an extra layer of protection and filtering.
The fabric, also used for the standard surgical mask, filters particles of up to 0.6 micron in size. The filter, made of 3 layers of fabric, will block particles as small as 0.1 micron, in contrast to the PM2.5 filter, which only blocks particles of up to 2.5 micron of size. In result, the filter will block out 99% of bacteria for optimal protection.
The TNT Filter will help you protect yourself from a variety of airborne viruses in the same fashion as the standard surgical mask.
The Bacterial Filtration Efficiency test has been done and officially approved on April 4th 2020.
