That says a spokesperson for the RIVM. “There is a run on face masks in our country, for fear that the corona virus will also appear here, but they hardly stop a possible infection” said a RIVM spokesman in the Telegraaf.
We believe that mouth masks are made to be worn for a short period of time, for example during a small job of a few minutes. So-called masks come in different degrees. (FFP1, FFP2 and FFP3) they have an efficiency of 80%, 94% and 99% respectively. Conversely, this means that 20%, 6% or 1% may leak through the filter. Not a good choice with particulate matter and certainly not with a potentially deadly virus, we think. The connection of the filter material with the face is also usually poor. That does not make the choice of these disposable dust caps the best, not to mention the cost and availability at the moment.
