The 3M Gas and Vapors Mask Set A2P3 consists of the 3M Half Mask 753 plus a replaceable filter set. The half mask is robust yet highly comfortable. It is made from skin-friendly silicone and features a drop-down strap system. This surrounding strap allows the mask to be comfortably worn in front of the chest during short work breaks, instead of having to remove it completely. Its innovative detail solutions and perfect seal fit through the structured facial seal also contribute to comfort. The 3M Cool Flow exhalation valve reduces breathing resistance and enables easy breathing. Warm and humid exhaled air is efficiently channeled away. Comfortable breathing is further supported by the dual filter system, which also has the added benefit of good weight distribution. The mask is characterized by a wide range of filters and spare parts and is easy to handle and maintain. The bayonet click filter connection works safely and quickly. The half mask is available in three sizes - this model is size L. The 3M Half Mask 753 is compatible with 3M safety glasses. The set includes two filters 655 (protection level A2), four particle insert filters 5935 (protection level P3R), and two filter covers 51.
