3M™ Reusable Half Mask HF-350 Series

3M™ Reusable Half Mask, HF-350 Series, has been designed with user comfort and convenience in mind. Featuring a 50mm filter thread, and compatible with the 3M™ Filters PV-251, the HF-350 is a convenient choice for users of the 3M™ Powered Air Respirator System Asbestos Kit, PV-300 Series, as the number of filter types that must be kept in stock can be minimised. Please note, the 3M™ Reusable Half Mask, HF-350 Series, was previously named the Scott™ AVIVA 50 Reusable Half Mask.

Features a reflex seal which contours comfortably to the wearer's face, a seal check mechanism for easier user seal checks, and an integrated speech panel for enhanced voice intelligibility while wearing the mask.
