RE: Vokz website could this be our mask?27 Dec 2020 10:28
@Tankhill I'm sure other holders will be annoyed at me going over this again but there are 3 main types of mask, IIRC medical face masks, these are designed to catch large droplets from the wearer they are quite poor at stopping particles being inhaled by the wearer, they also allow fine particles out through the sides where they don't fit the face very well, this is the type P2F have decided to make (quite why, well that's all about getting them out quickly and catching a fast buck)
The other types are FFP1, FFP2 &FFP3 unvented respirators, they are fitted to the face and protect the wearer from large and fine droplets, they are in short supply and what the NHS need more of.
N95 Vented Respirators - Does what the FFP type does but the vent makes them less effective at stopping fine particles being spread.
The P2F masks will still let out fine particles just as any IIRC mask, I have seen no tests mentioned of wether particles landed on the outside of the mask are neutralized before they are re-aerosolized by out going breath, as it stands I can see no advantage over a normal IIRC mask, perhaps testing should show that once some have been produced, that'sthe wrong way around though IMO.
