Har du nån källa på att mask inte skyddar? I princip alla rapporter och liknande jag hittar säger att FFP2+ skyddar till viss del, förutsatt att masken används korrekt och helst kompletteras med annan skyddsutrustning (t.ex. glasögon).

FFP1 refers to the least filtering of the three masks with an aerosol filtration of at least 80% and leakage to the inside of maximum 22%. This mask is mainly used as a dust mask (home renovations and various types of work).
FFP2 masks have a minimum of 94% filtration percentage and maximum 8% leakage to the inside. They are mainly used in construction, agriculture, and by healthcare professionals against influenza viruses. They are currently used for protection against the coronavirus.
FFP3 masks are the most filtering mask of the FFPs. With a minimum filtration percentage of 99% and maximum 2% leakage to the inside, they protect against very fine particles such as asbestos.

After the necessary premises made up to here, let's get to the point: can a mask protect us from Coronavirus (2019-nCoV)? Our experience in the production of respiratory protection devices makes us give an affirmative answer. Probably also in the case of 2019-nCoV, and with high probability in the less aggressive Coronaviruses, more common in our country.
Starting from our experience, we recommend three virtuous behaviours to protect against these viruses.
For preventive protection, it is advisable to wear disposable masks with at least the FFP2 protection level. The FFP2 filtering facepiece is suitable for protection from solid and/or non-volatile liquid particles. As an example, in our production are the masks BLS 128B/128BW, BLS 728, BLS 828.
