Edit: I bought a mask, I'm fairly neutral on the topic now but it became law and I'm not of an age where coronavirus should have little affect so it makes sense for others' protection.
if you're going to wear a mask, make sure it has a ridge on it and that you can breathe in and out normally without the mask moving. IF YOU BREATHE IN OR OUT HARD IT SHOULD MOVE SLIGHTLY BUT SHOULD MOULD BACK AND NOT ENTER YOUR MOUTH - IF IT ENTERS YOUR MOUTH AND GETS WET THEN IT'S POINTLESS. I used mjnd continuously for 5 hours and it seemed to have little effect on me.
They won't protect you and you're just adding more waste to the land and water... They also don't cover your eyes which is probably how most infection gets in.
According to
healthline and many other sources, COVID-19/the
novel coronavirus has a diameter of ~120nm while face masks only have a filter up to 300nm. I've been looking through information on facemasks have two main purposes:
1. Industrial: This is where someone is commonly working with small particles that need to be blocked going into their respiratory tract, such as wood workers and the like. Thre is also a use case for these in China for their pollution levels since carbon particulates above 100 micrometers in size are known for increasing the risk of asthma and 300 micrometers are known for producing carcinogens pretty quickly (I hope i got that the right way round).
2. Medical: Contrary to what a lot of people would thiink, the N95 model (I'm told is the most popular in medicine) actually just stops the surgeon/practitioner from projecting salivery deposits onto a patient and aren't actually for reducing the amount of infection spread between the two - probably the reason most doctors actually don't wear these. Quarrentine outfits probably give the doctor a certain amount of time in with a patient before they're changed, or have additional tuping to allow for them to receive air from outside the quarrentine unit (either that or they have more advanced filters, there's probably some fancy electrostatics devices for this sort of thing).
Anyway, your face masks just mean you're improving everyone else's air quality and may mean your immune system starts to become complacent (well if my nose is already covered, I clearly don't have to do anything)...
And the eyes link back with the same tubes as your nose and mouth, hence why when you have strong eye drops, you can taste them in the back of your mouth or when you throw up you feel your eyes burning a little.
IF you're under 35, it's highly unlikely it'll kill you.
If you're over 35 but are still pretty healthy, you shouldn't face much issue with it either. I've known 60&70 year olds to have caught pneumonia and barely noticed it (just got a temperature and shivers). If you worry about it too much or you're not healthy, that's when problems can start to arise and probably the hope with a lot of mainstream media that you will catch something and give a payout to big pharma (I'm looking at you USA)..
