Respirator 3M hh 670-6+3 3M — half-face reusable protective mask (model 670-6+3)

The 3M hh 670-6+3 is a half-face reusable protective mask designed to cover the nose and mouth and be used with compatible 3M filters and cartridges (sold separately). Constructed to deliver respiratory protection in a variety of work environments, this mask offers a form-fitting seal and supports interchangeable filtration elements for particulate, gas and vapour control when appropriate cartridges are installed. The design balances durability with user comfort for repeated use in industrial, maintenance and construction settings.

Advantages

The mask features a reusable body that reduces waste compared with disposable masks and allows selection of the appropriate filter type for the hazard. Soft face seal materials improve wearer comfort and help maintain a consistent fit. Adjustable straps enable a secure fit across different head sizes, while the low-profile design improves compatibility with other personal protective equipment such as safety goggles and helmets. The construction facilitates straightforward cleaning and inspection between uses.

How to use

Select appropriate 3M filters or cartridges for the specific hazard and fit them to the mask according to the filter manufacturer’s instructions. Position the mask over the nose and mouth, adjust the face seal so it sits evenly on the face, and tighten the head straps to achieve a comfortable, secure fit without excessive pressure. Perform a user seal check each time the mask is worn to confirm an adequate seal. After use, remove filters if the manufacturer recommends and clean the mask body following the supplied cleaning instructions before storage.

Usage recommendations

Use only filters and cartridges that are certified for the intended hazards and follow workplace safety procedures. Inspect the mask for damage, cracks or degraded materials before each use, and replace any sealing components that no longer provide an effective fit. Ensure compatible eye and head protection are used when required by the task.
