I have not had the time to put together some definitive words about Masks and respirators…sorry… the following is all I have to say...
As a summary , I opine that a body of potential bug customers may benefit from wearing a respirator.
Folks over 50 , with immune compromising conditions who move in crowded areas , probably should wear a mask.. no matter what the pigeon settling info says
Flat surgical masks have little if any protective effect as they are not airtight and should not be used
P95 (US) / P2 (Europe) moulded respirator masks are a very good first defence if fitted and used sensibly (this is why health professionals use them).
The virus is usually transported on a carrier, typically aerosols (watermist) and these masks are very effective in this area.
Moulded paper masks should be restricted to one usage over a limited time frame due to internal moisture build up.
To paraphrase another contributor.. doffing and donning correctly is extremely important.
Once fitted the exterior of the mask should be considered contaminated, so if you grab the front of mask to speak or eat…the whole process is a failure unless you refit and wash your hands or fit a new mask.
P3 respirators are a higher level of protection and in practical terms offer 99% protection.
I really do understand you are scared and keep pressing your opinion but unfortunately you keep missing the point (@Princess Fiona and others have also pointed out again and above) that masks are only going to be effective in certain scenarios by people that are trained properly on how to use them.
There is also a shortage of the properly rated masked where they need to be preserved for optimal community use in virus transmission (like on infected patients in care, for trained healthcare professionals dealing with infected patients etc). But even then you will see a lot of healthcare professionals probably wearing solid plastic shield visors over their masks as well (if they can get them!) because they know the virus is aerolised to a point the tiniest little crack (say if you crack a small smile in the mask and it moves) will allow it in.
If they were used broadly by normal healthy people as they go about their normal day they would actually work against us because people simply wouldn’t use them correctly.
They could even spread the virus faster becoming yet another contact transmission point. Unfortunately it is frighteningly easy to accidentally contact contaminate them, easy to wear them for longer than you should, accidentally pick the wrong one, not fit it perfectly, take it out of the box/bag incorrectly, not clean/sterilise the reusable one properly, the list goes on.
Your scenario of over 50’s wandering around in a mask in crowded spaces in their day to day life I’m afraid would just be, for most part ineffective, possibly put people at higher risk and take finite resources away from the people that need them.
