Particle filtering half mask (8228-2 FFP2)
Material composition
The surface layer is 45g non-woven fabric. The second layer is 45g FFP2 filter material. The inner layer is 220g acupuncture cotton.
Particle filtering half masks are fit to the face and are designed to protect the wearer rom hazardous airborne contaminants. They offer a balance of filtration and breathability. These masks have tangled fibers to filter pathogens in the air, and they fit close to the face. The edges form a good seal around the mouth and nose.
Fit testing is one of the testing methods to evaluate the mask.
Fit testing
Respirator fit testing is performed to determine how well the respirator fits the face of the wearer or the inward leakage of particles. In a quantitative fit test, the general approach is to measure the particle number concentration inside and outside of the respirator facepiece while the wearer performs a series of exercises; often sodium chloride or other particles are released outside the respirator to ensure that quantifiable particle concentrations penetrate the facepiece. The fit of the respirator is described by the fit factor, the ratio of the particle concentration outside the respirator to that inside the respirator facepiece. The fit test measures total inward leakage—the leakage of particulates through the face seal, valves, and gaskets, as well as penetration through the filter. In the EU, the fit factor is adjusted by the duration of inhalation and exhalation to determine total inward leakage (EU EN 149+A1, 2009). In the EU (EU EN 149+A1, 2009) and China (China National Standard GB 2626-2006, 2006), total inward leakage tests are required as part of the respirator certification process. In the USA, respirator fit testing is the responsibility of the employer, and is not part of the respirator certification process.
What is CE marking?
CE is a certification mark within the European Union. Products with a CE mark meet all the requirements regarding health, safety, and the environment. CE stands for Conformité Européenne, which roughly translated means in conformance with European regulations.
Products with CE marking may be sold and used anywhere within the European Economic Area (EEA). The CE marking is the manufacturer’s guarantee that the mask complies with current EU legislation.
