For reliable respiratory protection, it is crucial that a half mask fits tightly. Some models are therefore available in different sizes and the length of the straps can be individually adjusted for certain masks. However, the important thing to remember with all masks is that they can only fully fulfill their protective function if they are worn correctly. Please refer to the manufacturer's information on the Packaging.

The filters in the STEALTH masks must not be washed. It is recommended to wipe the face mask and the molded face piece with an antibacterial wipe after each use and to replace the filters every 28 days, provided the mask has been worn for 8 hours or more per day.

The slim, unobtrusive design of the STEALTH masks is designed for visors, helmets, goggles/safety glasses and other PPE. The STEALTH P3 Visor half mask already has an integrated face shield.

FFP masks FFP masks protect against the inhalation of very small, harmful particles such as droplets and aerosols - including those that other people may have exhaled.Filtering half masks are classified as FFP1, FFP2 or FFP3 depending on the retention capacity of the Particle filter. The higher the number, the greater the protective effect. LINK to page FFP masks Half masks with filter Hazardous substances are classified either as aerosols (particles and droplets) or as gases or vapours. The substance must be precisely classified on this basis. In addition, the filter class can be specified by different levels (P3, A1P3, A2P3, ABEK1P3). Image: ABEK_DE.png (for EN page ABEK_EN.png) Hengst offers combination filters for all three classes, which are suitable for the STEALTH half mask. The mask body is available without a filter and can be fitted with the appropriate combi filter and flexibly retrofitted depending on requirements.

This class indicates how well the system protects against the penetration of harmful substances. With TH3, the maximum permissible inward leakage is only 0.2 %. This means that the system is very effective at protecting the breathing air from harmful particles, gases and vapors, thus providing optimum protection for the wearer LINK to page Blower respiratory protection system

Filtering half masks - FFP masks They protect against inhalation and limit the exhalation of tiny, harmful particles such as droplets and aerosols. This is why they are important in many professional situations. LINK to page FFP masks Half masks with filter The half mask with filter ensures the filtration of droplets and aerosols when inhaled. It protects against aerosols from solid or liquid particles - primarily in an occupational context.

In accordance with HSE guidelines, it is recommended that a maintenance check of the respirator is carried out and the filters replaced every 28 days. The first day is the day the face mask is used for the first time. This applies if the mask has been worn for 8 or more hours a day. It is recommended to wipe the face piece with an antibacterial or alcohol wipe after each use to keep it clean and fresh.
