“Canada Post continues to monitor best practices and recommendations”
The fuck they are. Most likely the logic used by whoever is responsible for this decision was:
"OMG we've heard about N95 but then there's KN95 what's the difference? And we've heard something about counterfeit masks, what to do? Instead let's fall back on some random internal document someone wrote 21 months ago on this pesky topic. Yes this will endanger both our frontline workers and our customers by any commonsense standard, and very significantly so. But my ass is covered, so fuck them."
flight attendant would have none of that. He agreed to their surgical mask, but it wouldn’t fit underneath, so he had to dump the airgami. Older guy, had lung issues.
That mask seems extremely shady since they're advertising it as n95 without niosh approval. I'm not surprised the airline didn't trust it.
In the comparison with other n95 masks they also show a picture of what is clearly a fake n95 mask (a mislabeled kn95 mask) to act like their mask is superior because of its higher surface area when in reality many real n95 masks already have folds for higher surface area at one thirtieth of the price.
There's really no reason to wear that mask when legitimate n95 masks are so widely available.
That said if you just wear your own surgical mask on top from the start you can wear pretty much any mask on an airplane without being hassled.
Airgami passed NIOSH N95 pre-certification tests as performed by the accredited independent test lab, Nelson Labs. Air99 has never advertised Airgami as a NIOSH-approved N95. We have several disclaimers on our website to that effect. Please read them.
That said, Airgami is made with a top-quality, USA made, electrostatic melt-blown filter that Nelson Labs measured at a worst-case PFE of 98.3% and a median PFE of 99.8%.
When comparing filter size vs. other respirators, the mask in our picture is an average size KN95 mask. The picture was taken pre-pandemic when the KN95ers were falsely labeling their masks N95.
Regardless, the size of those masks is relatively constant, and that's what we are comparing in that picture ... filter size, not filter efficiency. Nothing deceptive about the picture. I'm sure the filter efficiency of the Airgami mask was far higher than the KN95 it was being compared against in that picture. Whether it's an N95, KN95, or counterfeit, the size is going to be roughly constant for boat-style, cup-style, or other style.
If we compare filter sizes vs. 3M Aura, for example, the Arigami filter is still significantly larger. Aaron "Mask Nerd" Collins measured Aura pressure drop at ~0.25 inches H2O vs. 0.17 inches H2O for Airgami, which is about a 30% difference in breathing resistance. It's no wonder many Airgami users say it is the most breathable mask they have ever worn.
