Canada gets the good stuff.

For $6.99 you can get a mask sample pack with a bunch of different sizes so you can figure out what size you want before you buy a whole pack of them.

I didn’t see anything like this in illmerica.

このQingping(チンピン?)というメーカーのCO2モニターはもうAliにもあった。だいぶ安い。英語圏では SmartAir というブランド名になっている。レビューは見てないがいちおうAranet4 の向こうを張った製品の位置付けだろう。いいものがあるとすぐに対抗して作る中国メーカーの瞬発力やばい。

☝️ if you're in the market for a legit CO2 monitor (ie w/ an NDIR sensor) these are three great options.

@safe_breathe's mask reviews are also 👌

Get a new mask? Aerosolize some bitterant around the edges to test if it seals -- gaps that are best measured in μm may be hard to feel.

When you use a disposable filtering facepiece respirator (eg N95, FFP2), how often do you don it before you dispose of it?

So I have again, which means I can go back to being even more insufferable about people wearing masks when they're out and about. \o/

Just a reminder, if you can't wear a mask for a medical reason, the fact that other people are wearing them around you still helps protect you.

So you should be advocating that everyone who can, wear a mask, even if you can't.

<-- KN95 or better

Dunno who needs to hear this, but people are still dying of . A family friend just passed after catching it a couple weeks ago.

Please mask up and talk to the mainstream, more trusting people in your life who think they're invincible because they got vaccinated a couple times. They seem to be the ones hurting the most this round and are generally unaware of the risk of organ damage and long covid.

What are masks for?

@eyesquash it's true that #BaggyBlues aren't great at protecting against airborne pathogens / bioaerosols, either for the wearer or those around them, though if everyone was wearing them in shared air, levels of transmission would still be much lower.

Even imperfect, incomplete masking with non-respirators by a majority of the population contributed to the eradication of a particular strain of influenza in 2020-21. By now, however, SARS-CoV-2 has mutated to be far more contagious than any strain of flu; it's probably neck and neck with measles -- the most transmissible pathogen we know -- at the very least.

Respirators, otoh, are incredibly effective at protecting the wearer, though they are even better at protecting others.

In practice, an #N95 can achieve upwards of 99% inward filtration efficacy. #P100 is even better -- upwards of 99.97% -- rendering scv2 impotent, as long as the fit+seal are good.

That's why hospital infection prevention and control policy specifies N95s, elastomerics, or PAPRs in the presence of airborne pathogens -- and why it's unconscionable that they've continued to stick their collective heads in the sand, ignore science and the relevant in-field experts, and deny that #CovidIsAirborne.

It's unfortunate that so many have fallen victim to the deliberate mis/disinfo that masks don't work, especially given that so many of us have gone 3+ years without contracting #SARSCoV2 -- or any other respiratory infection, for that matter.

"The device ... allows electrical potentials of up to 40,000 volts to be obtained in a compact device ... The efficiency of the masks was tested after being washed in water; efficiency was significantly restored after brief exposure to the electric field generated by the device."

A "well-fitting mask" that "fits well" is one that...

...provides adequate cover of one's face, neither being too small nor too large :drake_dislike:

...seals to one's face, completely encircling the nose+mouth such that no air can bypass the filtration material :drake_like:

Choose the right mask

Cloth 👎
Surgical 👎
Halloween 👎 🤪

N95 / FFP2 👍
N99 / FFP3 👍👍
N100 👍👍
P100 / elasto 👍👍👍

Wearing a mask doesn't stop COVID, not inhaling SARS2 stops COVID

If the mask you're wearing doesn't filter all the air you breathe, it can't protect you.
