[The Apprentice]

Two observation I gained as a former medic back in the mid 80's are, .

When a new mask is worn it does not take long for the precipitation in ones breath before a phenomenon called Wetting Out begins to occur, where the precipitation in ones breath begins to block the pores of the mask, surgical masks are designed to be like this so any droplets are caught by the absorbant materials to prevent them from entering an open wound, during what is known as the aseptic technique, in other words a two member team of the medical staff creating a temporary barrier between patient and doctor/nurse, these are larger bodies like droplets of saliva and or hair etc from falling into the treated area, especially in operating theatre, this is all they can stop.

One other thing to take into account is the fact that any barrier between face and the atmosphere can have detrimental effects to the normal flow of air and or breathing patterns, depending on the individual and their general health, and the more the face mask becomes wetted out the less effective it will be for the end user and inhibit the free flow of air into the body and when wetted out will readily spill out at the very poorly fitting sides, especially if you have a full beard.

So what the boffins in the think tanks have done is, they have put out into the public realm the knowledge that there are masks that have a small release valve fitted that allows any excess air/Co2 that might build up inside the mask to be vented, this small one way valve helps to get rid of the dirty or exhailed air from inside the mask, and on the next inhail this valve closes again to prevent the atmosphere outside of the mask, say a dusty environment from re-ntering as you take you next breath inwards.

However, this small valve would also let any and all viruses contained to be realesed directly into the atmosphere freely and be totally useless for this task, so you would be wasting your money buying such a mask, nothing can prevent a virus from entering the atmosphere, not one of these mask will prevent what the government is proposing.


They must realize that the truth about face masks is now over hyped and their attempts at using them as a muzzle will shortly come to an end and people will be able to smile once again at each other.
