Dräger X-plore 2100 Elastomeric Respirator Half Mask with P100 Filter. Comfortable with exceptional vocal clarity. Quick to don and doff. The Peppa Pig look may be polarising but if you can get over that it's a winner Image
The biggest con is the lack of exhalation valve filter, but I found an easy workaround for this. Cut a circular piece from a N95 or KF94 mask and place it inside on top of the exhalation port ImageImage
The mask is CDC/NIOSH and CE certified (EN 1827). This means it will has been tested by the CDC to ensure filtration capacity is as described. It is also AS/NZS 1716:2012 certified as an N95 respirator (but not TGA/ATRG approved for HCW use), though it is really more like an N99
The fact that this is a P100/N99/P3 masks means you get a higher grade of protection than from an N95/KF94 mask. That it is reusable means it will be much cheaper to run in the long term while being more comfortable than any N95
The elastomeric part of the mask is made of much softer and pliable material than most (eg the 3M 6000 series) and this is what makes it so comfortable, while moulding effortlessly to your face shape
The mask is made either of blue silicone or black EPDM. Only the blue version is offered on the Australian Amazon Dräger store. The black EPDM version is offered elsewhere. The box comes with 5 filters which should last for years making it economical amazon.com.au/Dräger-Respira…
The Canadian Amazon Dräger store offers both the blue silicone and the black EPDM versions. Unfortunately, there is no Dräger store on US Amazon where it is hard to find amazon.ca/Dräger-X-plore…
The one I got was the blue silicone version and it is exceedingly soft. The nice blue colour also reduces the Darth Vader styling which dogs the black EPDM version, while making it look less industrial and more socially acceptable
Additionally, the Dräger does not accumulate fluid/condensation inside as many elastomerics are prone to. I went for a walk in a 30C Sydney day and it did not get sweaty and unpleasant inside
This mask has been previously reviewed by @amandalhu who has forever and irreversibly created the association of this mask with Peppa Pig! As long as you can live with that it comes highly recommended
Note: caution if you're flying on an airline with this Dräger, even with the modification of an added N95 exhalation valve filter. A surgical mask might not fit over the top. Airlines or jurisdictions may have lists of approved masks. Check with your airline
Note: AU HCWs check with your OH&S dept if you want to wear this at work since it lacks ATRG approval even if it does have the AS 1716 approval, especially given lack of source control (exhalation valve filtration) in non-COVID areas
Note: being able to don/doff quickly is important. If I get a delivery at the door, I can get the Dräger on within seconds without struggling with the straps and adjusting the mask. Faster than any N95/KF94
Postscript: I have a medium (bordering on large) face as per sizing guides from 3M, Sundström, and CleanSpace. Nose bridge: medium, but the mask is so soft it won't matter whether you have a high or low bridge nose
Postscript 2: vocal clarity is important where workplace communication is critical. Too many masks muffle your voice. The Dräger permits you to be understood. If people need to lip-read, please look at the transparent @one_canopy (also has good vocals)

One misconception about Japan's political response to COVID is that it is a lovey-dovey response that's all about caring for the people. Nothing could be further from the truth Image
Notice how in this government video, they keep talking about business and economic practicalities. That's all they really care about, in a way that is quite brutal. The people don't even get access to free RATs or PCR testing.
The real difference in the JP govt response is that it is driven by a dominant neo-Keynesian macroeconomic paradigm, so unfashionable in the Anglosphere. It's a model that believes in nation-building through central investment in technologically based infrastructure

The world economy is being kept alive and functional by the #ZeroCOVID economics and social policy of the Far East (JP, TW, SG, PRC). Without it, global supply chains and the world economy would just crumble and collapse tomorrow
For those who say there is a “cost” to #ZeroCOVID: well, yes it's that you have to go to work keeping to the economy running, and you don't get to chill out while you lounge around for eternity as you push up daisies
And true, no country has had ZERO cases of COVID so #ZeroCOVID doesn't exist. PRC probably exaggerates its successes too. #ZeroCOVID aims towards zero by getting the Reff <1 in exponential decline. To do otherwise is to “live with” exponential eruptions of death

I am sorry to say that clinicians don't know what evidence is. And YES, you ARE an idiot if you reply that RCTs are the pinnacle of scientific methodology. Nobody in aerospace safety or automobile safety uses RCTs. Einstein's theory of relativity has never been subjected to RCTs
There is no doubt about this: the idea that all science progresses through RCTs is a MASSIVE lie. If you showed this pyramid to physicists, they would laugh at you. In physics and engineering, the ability of your model to make correct predictions is considered more important
Because the biological sciences are primitive, we are forced into the crude empiricism of RCTs. But aerosol science is more about physics and engineering, where predictive mathematical modelling remains valid. It isn't necessary to be abjectly reduced to primitive empiricism

It looks like my prediction is on its way to coming true. But the example of S Africa suggests that the peak in deaths may be greatly delayed following the Omicron case numbers peaking
Well after the Omicron wave cases peaked, the South African deaths still continue to climb at a remarkable rate. This may well repeat elsewhere. It's possible that delayed deaths from non-pneumonitis causes are the driver of this
We know from previous variants that deaths in the year after recovery are increased. Could it be that this insidious “post-recovery” death is just an Omicron specific accelerated form of #longCOVID? theguardian.com/world/2021/dec…

Japanese messaging. Top priority is correct masking. Keep it on while talking. No chin masking. Ensure gapless fit. Avoid speaking loudly in crowded, poorly ventilated spaces
The slogan in the lower third box that goes 「目指そうゼロ密!」 means "let's aim for zero transmission". It's a very #ZeroCOVID message. The majority (2/3) of the poster focuses on aerosol transmission
Actually, a more accurate translation is “let's aim for zero close contact”. Even more emphatic here. Eliminating the three forms of close contact: physical closeness, crowding, and closed spaces

Apparently, we are at the “nobody saw it coming” stage of idiocy now. You not only saw it coming, you absolutely wanted it to be that way. You want tens of thousands mass infected and countless dead. All for the good of the “economy”
We have doggedly repeated the dire warning that letting it rip will destroy the economy rather than save it. The destruction wrought by uncontrolled contagion on consumer and business confidence will wreak the economy, not save it, let alone save lives
Letting rip with death and destruction does nothing beneficial for the economy. Controlled intervention accompanied by support packages is far more helpful. But neoliberal anti-interventional macroeconomic dogma has been allowed to dominate management
