This connection is very intuitive, it allows a fast and safe fastening of the mask. It has a locking mechanism that allows the user to know if the filter has been placed correctly.
The quality of the activated carbons used by BLS for the filtration of gases and vapours meets high standards of safety ensuring excellent filtration performances. They are produced without toxic additives such as Hexavalent Chromium (Cr VI) and they are food grade certified (REGVE231/2017).
Tested Against Formaldehyde
BLS has carried out specific NIOSH tests in an accredited Laboratory to verify the penetration of Formaldehyde in its carbons used for the ABEK and ABE filters.
