Half masks are used to protect the respiratory tract from harmful substances such as particles, inorganic and organic gases and vapours. They are used in areas such as the chemical industry, welding or the construction industry, where high concentrations of these pollutants can occur.

Half masks with filters are respiratory protection masks that enclose the mouth and nose and are used to protect against hazardous working or harmful substances such as aerosols, dust, gas or harmful vapours. Their filter performance depends on the filters used. Their sealing line runs over the bridge of the nose, the cheekbones and below the chin. They can have inhalation and exhalation valves as well as a speaking membrane. In contrast to full face masks, they are lighter and more compact to wear.
If you need to protect yourself not only from particles, but also from gases and vapours, you should use a respirator half mask instead of a particle-filtering half mask (half mask with particle filter, also known as an FFP mask).
Half masks with filters are used in numerous sectors such as industry, agriculture, construction, the pharmaceutical industry and healthcare, as well as in the chemical industry and in the extraction of raw materials.
It is recommended that you choose a branded product. Make sure you select the right respirator for your purposes and the respective use according to the respective protection class. Check the mask for damage.
When wearing a half mask with filter, it is essential to check whether it is compatible with the safety goggles you already have or have purchased in addition, in order to protect your eyes correctly from irritating gases and vapours. Otherwise, a full face mask with filter must be used. The accuracy of fit and a good seal should generally be checked.
When working with an open flame, the possible risk of ignition of the filters (especially with gas or combination filters) should also be taken into account.
For a half mask to provide reliable protection, it must fit well and be put on correctly. Choose between the size variants S/M and M/L.
For half masks with a filter system, attention should be paid to the brand quality of the product. BLS has been one of Europe's leading and largest suppliers of professional respiratory protection for over 50 years.
The BLS 4000S half mask has a double filter system. The filter is attached quickly and reliably using a bayonet system. The soft rubber moulds to the face, fits reliably and is therefore very comfortable to wear. The individual components can be easily dismantled and cleaned.
Half-face respirators with a bayonet system are characterised by a number of key advantages. The quick and easy filter change by means of a rotary movement enables efficient handling and fast reaction to changing working environments.
The fixed bayonet connection ensures that the filters are securely fastened and do not fall off during use. In addition, the system offers a high level of compatibility with different filter types, so that the mask can be flexibly adapted to different requirements. The special connection type also improves the fit of the mask on the face, resulting in a better seal and more effective protection.
In a double filter system, two filters are attached to the sides of the mask. This offers several advantages:
