N95 mask has a filtration device able to stop 95% of 0.3 micrometre (0.0003 millimetre) particles. Even though the coronavirus is estimated to be about 0.07 to 0.09 micrometres, virus particles are normally carried in droplets somewhat bigger than this, making the 0.3 micrometre limit quite adequate for protecting the wearer when combined with other protective equipment. Contrast this with cloth fibres, of the type you might use for a homemade mask. The gap between most cloth fibres found in the home depends on weave thickness and can be 1,000 times bigger compared with the N95 mask – around 1 to 0.1 millimetres. Although additive effects (combining with physical distancing, frequent hand washing and avoiding crowded spaces) should be considered, the benefits are further complicated by factors such as material type, number of layers, fit, face shape, frequency of adjusting, facial hair and the effect of having a moist and increasingly dirty piece of cloth over your face.
So from the scientific perspective, the evidence does seem fairly clear: a well-designed mask combined with the right safety equipment and behaviour has a protective effect, but homemade cloth face masks are simply too variable to be relied on for protection of yourself or others.
As there is an availability problem, it makes sense that the public are not urged to compete with medical staff for limited supplies of the most effective masks. Promoting alternative face coverings helps to prevent this competition.
Signalling [sic] to others that you are taking this seriously and trying to respect their safety as well as your own is, therefore, an important statement of solidarity.

To get into a 'mask mandatory' store, I stuck a kleenex under the nose bridge of my glasses long ways so it hung down covering nose and mouth. Soon as I cleared the doors, back in the pocket it went.
Yeah. My not wearing one is a important statement of "MYOB".
Wearing a mask causes a person to breathe more CO2 than normal.
I haven’t worn one and won’t wear one.
Wow.

Masks Don't Work: A Review of Science Relevant to Covic-19 Social Policy
Masks and respirators do not work.
There have been extensive randomized controlled trial (RCT) studies, and meta-analysis reviews of RCT studies, which all show that masks and respirators do not work to prevent respiratory influenza-like illnesses, or respiratory illnesses believed to be transmitted by droplets and aerosol particles.
Furthermore, the relevant known physics and biology, which I review, are such that masks and respirators should not work. It would be a paradox if masks and respirators worked, given what we know about viral respiratory diseases: The main transmission path is long-residence-time aerosol particles (< 2.5 μm), which are too fine to be blocked, and the minimum-infective-dose is smaller than one aerosol particle.
The present paper about masks illustrates the degree to which governments, the mainstream media, and institutional propagandists can decide to operate in a science vacuum, or select only incomplete science that serves their interests. Such recklessness is also certainly the case with the current global lockdown of over 1 billion people, an unprecedented experiment in medical and political history.
No RCT study with verified outcome shows a benefit for HCW or community members in households to wearing a mask or respirator. There is no such study. There are no exceptions.
Likewise, no study exists that shows a benefit from a broad policy to wear masks in public (more on this below).
Furthermore, if there were any benefit to wearing a mask, because of the blocking power against droplets and aerosol particles, then there should be more benefit from wearing a respirator (N95) compared to a surgical mask, yet several large meta-analyses, and all the RCT, prove that there is no such relative benefit.
Masks and respirators do not work.
That’s the main reason I’m wearing it these days.
I was in a mask mandatory store...... for the customers.
Wearing the mask was supposed to be mandatory but upon entering the store, you could see most of the employees were not wearing one.
“ May I quote you on that?”
Please do!
Yahoos like you are going to destroy the economic recovery with you bullshit “science”. Of course masks protect, you have to be an absolute moron to think they don’t or just brainwashed. So, you think it is a conservative issue? What a fool, any thinking person is for wearing masks and doing mitigation...it is yahoos who endanger our reopening and economic recovery who don’t want to continue mitigation. There is a lot more scientific testing/studies showing masks offer protection than the yahoo propaganda your finding.
Hi, you can start here and then go to links or search for mask efficiency studies...you will find the ones supporting masks are more reputable sources than the ones with the insane claim they don’t protect.

How about you remain hiding under your bed quivering in fear while the rest of us live our lives without feeling like we're in a surgical suite?
Let me know when you figure out how to stop something requiring an electron microscope to see with a piece of cloth wrapped over your moronic face -- or some other mask that allows half the air you breathe in and out to escape around the outside edges. Whatever you do, keep shouting science at everyone so you look like an even bigger fool. The stupid is strong within you.
This is what I found: https://www.cidrap.umn.edu/news-perspective/2020/04/commentary-masks-all-covid-19-not-based-sound-data
What a moron you are...really. To me, the only thing you can think of is the person who disagrees with your moronic views is we are cowardly? Ha, get a life scumbag...
Listen dumb shit...masks have helped prevent spread of infection since the civil war. Your alcohol soaked brainwashed mind probably cannot wrap itself around the concept. but, in any event screw you pussy nipple.
