Dräger offer the A1 Bayonet filters as a means of protection against class 1 organic gases and vapours (of boiling point >65°C). These filters are for gases only and do not protect against particulates. This pack contains 10 pairs (20 pieces).

Bayonet filters are also known as twin filters. They have a bayonet connection, which makes them suitable for half face masks such as the X-plore 3300 and 3500, and also the X-plore 5500 full face mask.
