3M Maintenance Free Disposable Half Mask

3M Maintenance Free Disposable Half Mask

The 3M 4255+ A2P3 RD Disposable Half Mask Respirator delivers high-performance protection in a simple, maintenance-free design.

Ideal for environments with organic vapours and hazardous particulates, this ready-to-use mask features integrated filters, eliminating the need for assembly, maintenance, or replacement parts.

A soft, textured face seal ensures a secure and comfortable fit, while the lightweight, well-balanced construction makes it suitable for extended wear.

Its low-profile, streamlined shape improves peripheral vision, and twin inhalation valves work with bonded carbon filters to reduce breathing resistance.

The parabolic exhalation valve minimises heat build-up for cooler, easier breathing. With an easy-adjust head cradle and neck strap, the 3M 4255+ offers quick, reliable fitting.

Certified to EN405:2001 + A1:2009, this mask provides A2P3 R D protection for organic vapours (up to 10x WEL or 5000 ppm) and particulates (up to 20x WEL), and meets the clogging resistance standards for fine dust environments.
