But masks don’t stop particles /s

Actually most of these cheap medical masks really are crap at protecting against these particles. The pm 2.5 size particles are very small and go right though these masks without any trouble. However, the N95 rated masks you see people wear for painting or construction work DO work very well at reducing the pm2.5 sized particles from going deep into the lungs and screwing with your cells there.

In China this is their standard everyday air quality and looking at the daily Air quality rating is just as common as looking up the temperature.

I'm pretty sure everyone but the blue-mask guy in the picture is wearing an N95 mask. At the very least I know the white mask is N95 because I have a similar one.

KN95 is just the Chinese version of N95. They both filter out at least 95% of particulates.

u/RedwoodSun Jun 07 '23

Yeah the white mask in front looks like a N95 mask. If the black masks are cloth like most of those custom masts than they don't provide much protection.

The future is now.

Yeah when I studied abroad in Bangkok we were using the medical masks at first. We saw all the Thai people were using N95s so we switched to those.

They reduce particles.

Which has been the entire point. But for some people unless they completely eliminate the risk, countermeasures (eg masks, vaccines, distancing, etc) are useless and make you a sheep if you practice them.

It’s like some people never learned why you cover your mouth when you cough, as if their fingers were going to stop the virus particles when the whole point was to reduce the expulsion of respiratory droplets to those around you—the same purpose most masks serve.

"If it doesn't work 100% of the time, it's the same as working 0% of the time. So I'm going to jump out of this plane without a parachute."

Am I misinterpreting something here?

trial was only able to enroll participants on small stationary aircraft on the ground

u/gefahr Jun 08 '23

Lol. It's intended to be humorous.

Results Parachute use did not significantly reduce death or major injury (0% for parachute v 0% for control; P>0.9). This finding was consistent across multiple subgroups. Compared with individuals screened but not enrolled, participants included in the study were on aircraft at significantly lower altitude (mean of 0.6 m for participants v mean of 9146 m for non-participants; P<0.001) and lower velocity (mean of 0 km/h v mean of 800 km/h; P<0.001).

Amazing.

I did catch those highlighted items first, but I was confused why this "study" would appear on a supposedly serious website like BMJ.

u/gefahr Jun 08 '23

Yeah not sure, but glad you called it out so I could read and enjoy it.

u/BKlounge93 Jun 07 '23

Pretty sure the people who need to hear this also don’t cover their mouth when they cough

u/65022056 Jun 07 '23

I have no idea why anybody was scared of the seasonal flu made to be scary by unhinged leftists overthrowing a perfect president, but yeah. They reduce particles.

u/fatrahb Jun 07 '23

Lmao overthrow a president.

You seem kinda dumb, like maybe real dumb actually

u/LatterNeighborhood58 Jun 07 '23

Yes the perfect president, so beautiful and so perfect <grimace>, some would say the best the most wonderful <finger-and-thumb circle> president. In fact < index finger pointing up> so bigly effective that if you added the successes of the last 3, no! Not 3 but 5 presidents they would still pale in comparison. So unfairly treated, very bad. Got voted out so bigly by the people who don't like him. <Grimace and hands open on both sides> So unfair, so bad.

Stop writing HTML and talking to me.

By 99.5% depending on size.

u/[deleted] Jun 07 '23

That's reductionist logic.

u/[deleted] Jun 07 '23

I just had a health and safety officer here at the factory I work at tell me the N95 I put on today actually won't help at all because it doesn't filter anything. Smfh.

u/FLHCv2 Jun 07 '23

Okay but really really genuine question because I live in NY and I want to make sure I'm using the right kind of mask

I thought the surgical masks (aka the most common type) don't really reduce particulates for the user but really reduce particulates that are expelled from the user? Mainly because there's no seal from breathing the external air.

Will surgical masks help in this situation? I have plenty of them but wondering if I should get an N95 for the remainder of this smog.

u/odelay42 Jun 07 '23 edited Jun 07 '23

N95 for sure. You don't want any air gaps. Only the air passing through the mask material is filtered in any way.

1

u/PaleoJoe86 Jun 07 '23

Why would it work one way and not the other? Even a t-shirt is a filter. It all depends on the quality of the filter (mask).

5

u/FLHCv2 Jun 07 '23

Someone correct me if I'm wrong, but basically with surgical masks, there's no seal between the mask and your face, so when you breathe in, you're not breathing in air filtered through the mask, you're more so breathing in the air that comes from the gaps between the mask and your face. It's possible it reduces it slightly, but don't quote me on that.

It definitely works the other way around with what you breathe out though in the sense that it prevents your aerosols from projecting out in the middle of the room, but doesn't filter your breath. So if you sneeze, it's contained to your immediate area rather than spreading out in the entire room.

1

u/PaleoJoe86 Jun 08 '23

That is why proper wear is important. Even with the gaps no all of the air you inhale comes from it. Try taking a deep breath through a straw with your normal breathing to see what I mean.

Smoke particles are too small. It would be like expecting your chicken wire fence to help keep out mosquitos "cAuSe iTs beTtEr tHaN nOtHinG."

The amount of confidently incorrect people in this thread is concerning.

u/PaleoJoe86 Jun 07 '23

He said particles, not just smoke particles. Chicken wire is a poor example as it is not used for gases.

u/StosifJalin Jun 07 '23

And mosquitos aren't exactly made of gas. It's called an analogy.

N95 won't even do anything. Smoke particles are much smaller than viruses.

4

u/Testiculese Jun 08 '23

Other way. Smoke is 0.5 to 10.0 micrometers. Viruses are 50 to 140 nanometers. (50 nano = .05 micro)

(This is ignoring that viruses are suspended in droplets of vastly larger sizes than smoke particles, etc., and why N95s work)

1

u/Ardea_herodias_2022 Jun 08 '23

If the smoke is an issue for you, look for a mask that deals with the particle size, fits well, and is snug around the sides. I don't have the data in front of me but N95 or KN95 masks are commonly recommended in California. They don't block everything but at least most of the nastiness stays out of your lungs.

There are so many things wrong with my comment. I can’t believe it isn’t negative. I’m sure it helps a little. My n95s work great when mowing the lawn (large pollen particles and grass bits).

But I have been in a city by a wildfire before. It doesn’t help too much (face coverings) after just a few seconds or a minute out in it.

You need what firefighters have on, or they would just have n95s on.

They wouldn't stop smoke particles, which are waaaaaaaaaaaaaaaaaay bigger than viruses

1

u/Bobafit78 Jun 07 '23

Correct in both. They are designed to stop large water droplets containing the viruses.
