Some masks better than others

[basketcase]

Cloth and surgical masks stop air as well as a mask would stop car exhaust if you put the mask around a muffler.

Physics 101

Wow. So molecules of CO, CO2 and the various sulphates and nitrates can pass through masks? What about O2? You really can use a physics refresher on the size difference between a molecule and a droplet/aerosol. A surgical mask will stop most of the particulate ("smoke") though with the volume of gas pushed through a muffler, it will get clogged up pretty fast.

A mask is not a hazmat suit. They are not meant to filter out everything. Their job is mainly to reduce the chance and velocity of droplets and aerosols containing the virus which is the main vector of transmission. Even cheap cloth masks will stop large droplets and medical grade surgical masks will stop most aerosols. And again, the effectiveness of a level 3 surgical mask is not much different than that of an N95 that isn't professionally fitted.

Would making everyone wear N95 masks be effective? Maybe but not unless people take the time to wear them properly and unless the knock-off masks are taken off the market.

This is the same strawman argument we've been hearing for two years. Covid virus is too small for surgical/cloth masks, it is airborne, it passes right through the rag you have on your face . The last two weeks should have driven the point home, yet too many are still living in denial.

 

[basketcase]

ok. So you’re way toooo far left.

I spent 2 years wearing a cloth mask which has just been proven as a waste of time. Would you say something about the kind of mask I’m wearing. I’d love to see that.

Btw. I’m in the middle. Keeping the peace.

Speaking up for my own safety and pushing personal responsibility is too far left?

It's funny because several times in this thread you've admitted that viruses don;'t travel on their own then go back to pretending that there are free virions flying through the air.

And yes, virus particles are much larger than molecules. Molecules are about 1/100th the size of most viruses.

Omicron is spreading in households unmasked NOT through properly masked.

No way! Really?

 

[jcpro]

There's no such thing as "properly masked" outside of the fitted n95. Not against a virus with the average size of .125 microns. The properly fitted n95 is barely/partially effective against the airborne covid and very effective against the fully symptomatic emissions. The cloth masks are virtue signaling against the presymptomatic and post symptomatic airborne emissions. Hence, we are witnessing, this very moment, the dramatic increase in infections among the 100% masked population in Canada. If the spread was mostly limited to households, we simply would not be seeing the latest spike in cases. The infection rates would have stayed more or less constant.

Personal responsibility yes. That’s why I wear a mask but safety. ffs. You’re having a laugh

 

[The Fox]

So I'm going to guess you believe Omicron and Delta and other variants are all the same in regards to infection and severity?? Please enlighten us Dr. Jcpro.

I wish people like you would just self isolate for ever. Leave the rest of the world for fun people

 

[Mr. Secks]

It's truly sad to see how so many people argue and hate each other over bullcrap like masks/social distancing vs. a 99.98% survival rate virus (regular influenza = 99.9%).

Real issues: Whether Canada will follow Austria/France and threaten imprisoning and inoculating their citizens against our wills if we choose not to take experimental shots (where are the "My body my choice" abortionists now?); Whether we should peacefully surrender to being taken to camps against our will as in Australia; Whether we support segregation/the establishment of second-class citizens who have fewer rights (like blacks in the early US)or no rights at all and are seen as inhuman/valueless and a threat (like WW2 Nazi genocide).

So the world government has divided us into small, weak groups/individuals fighting each other while the 1% takes away our meager semblances of freedom - and party maskless with the lower class in lockdown! Why argue over masks?

 

[basketcase]

This is the same strawman argument we've been hearing for two years....

Yes, the "strawman" of scientific evidence.

it is airborne

Sadly people see the term airborne and don't bother reading that it means aerosols stay in the air, not free virions floating around.

But I'm sure you can provide a study that says otherwise.

There's no such thing as "properly masked" outside of the fitted n95.

And what studies do you base this on?

p.s. properly fitted means having professionals determine your fit and being clean shaven

 

[benstt]

Please tell us, what is the minimum size Covid viral particle that can float in the air in micrometers (μm)??

Failure of you giving us an exact number means you are dodging the question

Many things 'can' happen, but studies have shown that masks make a difference in the real world.

I was in a rush to get into the Beer Store, so I held the surgical mask in my left hand and pressed it hard against my nose and mouth. The Beer Store guy said not good enough. Said I need to wear the mask "properly".

Was he right?

Yes, he was because if not worn properly you might as well not be wearing it at all.

Of Course he's right!, You mean to tell me that you can't take an extra 3 seconds to put the mask on properly?

You're both wrong........Surgical masks are useless.

Good for virtue signaling though but that's about it.

The numbers dont show that

Of course he was right. You suppose to wear your mask loosely over your face- you get extra points if you have a beard.

 

[massman]

They do, otherwise every healthcare worker who look after covid patients would get infected, and in fact, infection from patient to healthcare worker is rare. Even in the absence of n95s.
Non fit tested Kn95 are pretty good. Just make sure the seal on your face is good, with no air leaks.
Even surgical masks will reduce spread in the immediate environment. The are good at droplet filtration and will filter some aerosols. (Tho not 95%). Cloth masks too, just less so.

 

[The Fox]

After going through Covid and seeing my family and friends do the same. I actually question why we are taking any precautions at all that we dont usually do during winter months.

Lets just stop measuring and tracking covid. Then no one will know it’s exists, case solved.
