Ffa1p3 Maintenance Free Half Mask

The facial body is made of hypoallergenic thermoplastic. Both the design and the used material provide air-tightness, preventing air from filtering inside through the face/mask union. The main body houses two non-replaceable filters. Their position offers wide visual field. It has a large diameter exhalation valve for optimal exhalation. The fastening harness has a comfortable neck and head strap that can be easily adjusted to the appropriate length thanks to its easylock system. Once removed from its original packaging, the mask should be replaced every sixmonths at the most. Replace the mask if it retains any characteristic of the contaminant (smell, taste, irritation) or an increase in resistance to breathing is observed. The contaminated area must be abandoned at that same moment. Includes a resealable bag for hygienic storage and transportation.
