4000 series maintenance free half masks are simple and ready-to-use respirators with an integrated cartridge and filters. They provide protection against a range of organic gases and vapours, and combination particulate hazards.

  • Newly enhanced valve assembly reduces exhalation breathing resistance for improved breathing comfort
  • Lightweight, well-balanced, low-profile design
  • Integrated cartridge and filters are ready to use and maintenance free
  • Adjustable head cradle and easy to fasten neck straps
  • Centrally-positioned exhalation valve reduces heat and moisture build-up
  • Includes a resealable bag for hygienic storage and transportation

The lightweight, well-balanced design features a centrally-positioned exhalation valve that helps reduce heat and moisture build up, increasing comfort in hot and humid conditions.

The integrated cartridge and filters are maintenance free. Simply use them until the change-out schedule indicates a replacement is needed or when the filters are full, and then discard. Masks will provide up to 40 hours of use life when stored in the resealable bag provided. An adjustable head cradle helps fit to a broad range of head shapes and sizes, and the neck straps are easy to fasten. The low-profile design won’t hinder peripheral vision, and the two large, bonded-carbon filters ensure low breathing resistance.
