A rash of mask tweets ๐Ÿงต.

On elastomeric masks, N95s, KN95s, FFP2s, KF94s, care and fit, sourcing, testing, real-world examples & tips, warnings, children's masks, cute alternatives - and why you might want to upgrade now.

Why you might want to strengthen your first and most important line of defense.

One of the best primers on new mask technology in one short interview.

cbsnews.com/video/some-expโ€ฆ

Teases out technical classifications of 'hi-fi' (high-filtration) masks such as N95s, KN95s or KF94s - and why cloth & surgical masks are not an option now.

Think '2022', not '1918'. Image
'With Omicron, you need a mask that means business'.

A good, complete article (23rd Dec 2021) on why hi-fi masks are fundamental in the face of increasingly infectious variants.

#Mask #Masks #MaskUp #facemask #facemasks #COVIDisAirborne ImageImageImageImage
Wearing a safe mask brings everyday stress levels right down to manageable proportions again - important when we've been living in an incessant state of apprehension for so long.

Anything that enables us to carry on normal activities without fear is a massive mental bonus. Image
The technology to keep humans free from airborne disease isn't new.

The Texas Center for Infectious Diseaseย - a TB hospital - issued its staff with re-usable elastomeric respirators in 1996. Since then, not one of their healthcare workers has ever been infected at work.

So how do I clean a disposable #N95/#FFP2 mask like the Aura?



โŒ You don't. Don't wash, or spray with hand-sanitiser or alcohol: it will damage them.

โœ… Rotate 7 masks on a weekly basis, and dispose of after 5 uses. Better still, hang them in the sun. ImageImageImageImage
If you're anxious about landfill waste, there are reusable, disinfectable options - like the ultra-light #N95 #Airgami whose origami origins and scientific makeover create an elegant, safe #mask with a self-conforming fit.

Teachers and lecturers favour the Airgami for clear voice projection; mountain-bikers and hikers for unhampered breathability; and glasses- and hearing-aid wearers report easy compatibility. ImageImageImageImage
A note on fit.

The #GVS #Elipse #P100 has its own proprietary fit-test kit - the SPM414 - bought separately.

If you want an airtight #FFP2/#N95 seal, consider taping the edges of the #mask to your face with hypoallergenic tape.

Stubble and beards severely affect a safe seal. ImageImageImageImage
A note on haircuts.

Both the #elastomeric GVS Elipse #P100 and the #FFP2/#N95 3M Aura #masks use headbands; the #Airgami has options for headbands or ear-loops.

For a no-risk #haircut: tape an #Aura to your face & release the headbands; or use an alternative N95 with ear-loops. Image
On #N95 hesitancy, and switching from cloth to hi-fi #masks.

๐Ÿ‘€ ImageImageImageImage
Eye protection is something I've never used, and have no experience of. In shops and other face-to-face settings, I wear glasses and sanitise afterwards. On a crowded subway/tube/MRT, I would certainly wear sealed, wraparound goggles. Taste and fit? Time to do your own research. ImageImageImageImage
A word on #children and #masks.

If your views on the topic approach anywhere near this spectrum of bat-nuttiness, the next part of this thread is not for you.

But as any good primary school teacher will tell you: ignore the bad, and praise the good.

So let's cut to the quick.

๐ŸฆŽ From hereon in: notes and additions to the thread.



Mask study comparing fit:

ยฐ 'N95 respirators had average total inward leakage (TIL) of <1%;
ยฐ KN95s (ear loops) had an average 16% TIL;
ยฐ Cloth & procedure [surgical] masks had TILs from 71% - 44%.' Image
From Aaron Collins:

"The key thing with ear-loop masks is that users need adjustable ear loops. Ear-loop masks are more sensitive to mask-sizing."
Inward-leakage test results:

โ€ข An adjusted FFP2/N95 vs. non-adjusted;
โ€ข An FFP2/N95 with a surgical over the top;
โ—‹ An #FFP2/#N95 mask taped to the face;
โ€ข A surgical mask on its own.

โœ… A little hypoallergenic tape can save you a lot of brain/kidney/liver damage.

One of the tweets in my mask thread annoys me. It needs fixing.

Rotate disposable, high-quality masks: โœ….

My last comment? I live in the tropics. Black mold is a big issue in 95% humidity. Plenty of sunlight/UV, so hanging masks in the sun between rotations helps *too*... ๐Ÿ™๐Ÿฝ Image

Here's another note on masking:

ubudhigh.com/bali_2020/a010โ€ฆ

#MaskUp #MasksSaveLives #MasksInSchools #GoElastomeric #P100 #N95 #FFP2 #Masks ImageImage


As if you needed reminding.

wired.com/story/the-physโ€ฆ

'A well-sealed FFP2/3 [N95/N99] mask is the single greatest tool humankind has come up with to prevent initial infection, further spread and mutations - as well as an endless pandemic.'

#MaskUp ImageImage
I hadn't realised that the 'Vax-Only and Nothing Else' crew were a thing; or that they are so incredibly toxic & wrong-headed; and as dangerous as any of the other extremist Covid bands.



A thread on putting them right: and why vax-and-mask matters. ImageImageImageImage
On why you need to upgrade your N95s, N99s, FFP2s or FFP3s to an elastomeric mask with #P100 filters.

Up to you. Your throat, your frontal lobe, your heart, your kidneys, your thyroid, your retinas, your liver & your skin.



Bulletproof? #ElastoP100 Image
I think the general idea is to mask up. It saves foetuses from dying in the womb, and pregnant ladies from leaving their husbands 30 years early, and prevents older people from ending up in a care home 5 or 10 years before their time.

I especially approve of this chap's eye-pro. Image


Your Monkeypox. Image
If SARS-CoV-2 can infect via droplets & eyes, and airborne Monkeypox can infect via droplets (and exchanges of bodily fluids & fomites & physical contact), then eye-protection also makes sense.

I went for the Bollรฉ CONTPSI Bronze. Ideal match with an elastomeric GVS Elipse P100. ImageImageImageImage


I told you the unvalved GVS (M/L) SPR644 #P100 #elastomeric #mask was good: so good that stock has run out.

Amazon? A 404.

You're in luck if you have a smaller face: the (S/M) SPR643 is still on the shelves.

#KillingAintCool ImageImageImage
Slightly off-topic: but a major reason why many can't/don't want to be bothered to mask up.



And have convinced themselves that bringing others down to their own level of brash selfishness is fine.

An interesting psychological take here.

#CovidKills Image
I'm now officially fairly tired of being told that I'm fearful while I wear a respirator - not just for myself, but for the ones I love.



To the naysayers in my life: You're dangerous.

I get:

"Life is for living [in a care home after you can't remember how many kids you've had / with an eternal Grade 1 headache / after a stroke]!"

and

"Time to live your best life [while knocking off a few foetuses]!"

From family.

An extremely important kernel of knowledge while you're using a high-quality respirator like a #P100 #elastomeric: yes, you will be able to smell through it. And yes, your respirator (if it's fitted well) will continue to protect you from C-19.

โœ… Verdict? Go for it.

#ElastomericBulletproof #Mask ImageImageImageImage
A crucial advantage of choosing an #elastomeric #respirator over a more standard #N95/#N99 #FFP2/#FFP3 #mask like the 3M Aura or VFlex is the extremely high first-off chance of an airtight seal.

This can't be understated.

#GoElastomeric #P100 #N100 #ElastomericBulletproof ImageImage


At this point, where the majority have been fooled/willingly cajoled into dumping their masks, I can only see an elastomeric as the go-to protection.

But if you have to wear an N95/FFP2, double-sided tape is heavily recommended to achieve a better seal. Image


If you need an N95/FFP2 that is MRI- and CT-safe, then the strapless, metalless, self-adhesive Readimask is your option.

readimask.com/why-readimask-โ€ฆ

Also a solid choice if you must sleep in a mask - in a hospital, or on a 'plane.

nb. Haircuts.

Keep your glasses on; go full goggle; or buy some clear wraparounds like the 'Bollรฉ CONTPSI Bronze'. ImageImageImage

If you want 100% bona fide products, a respirator/mask manufacturer may well link direct to their Amazon shop from their official website - eg. GVS or 3M.

#OneWayMasking #MaskUp #GoFullElastomeric #Masks ImageImage


I'm not recommending N95s or FFP2s from now.

They worked well enough for 2021's variants in a two-way masking environment; but they will certainly not offer you bulletproof protection in 2022.
