3M 4279+ FFABEK1P3 R D, 4000+ Series Half-Type Half Mask

Face harmful vapours head-on with this half mask from 3M. It's a versatile option that filters out organic and inorganic gases, along with ammonia and acids. For convenience, the mask is reusable and doesn't need maintenance or filter changes. A centrally-positioned exhalation valve prevents heat and moisture build-up, so you stay comfortable and eyewear won't fog. As it's ready to use straight out of the box with no setup, this is a hassle-free choice.

• Adjustable cradle straps for a non-slip fit without pressure
• Half-mask style means your vision isn't obscured and you can combine it with glasses and ear defenders
• Two bonded-carbon filters for minimal breathing resistance

• Manufacturing industry
• Oil and gas refineries
• Construction sites

This depends on the level of contamination in your workplace. If you notice it's becoming harder to breathe, it's likely the filters are full and you need a new mask.
