Masks are loose-fitting, covering your nose and mouth. They generally have three layers with a PP melt brown non-woven fabric as the middle layer which acts as the filter. They are designed to provide one-way protection to capture coughs etc. from the wearer. However, studies have shown that, compared with the N95/FFP2, they do provide an approximately similar level of prevention of transmission of influenza in close contact clinical environments.
The Type IIR (European Standard) fluid-resistant surgical mask is the “regular” surgical mask often used in clinical settings – this is the standard mask you see doctors and nurses wear. It is substantially better than most homemade cloth masks. The fluid resistance is why we suggest the Type IIR masks for most day to day use where you may be in close (under 2 metres) contact with others.
We also offer a protective (non-medical) mask FFP1 EN149 masks. This offers a reasonable level of filtration. We suggest it is suitable for uncrowded public places.
