For those who don't mind buying masks from Taobao, here's another store now available via Superbuy. COI: the owner of this store, Mr. Fang, is a friend of mine, pretty much like @zhouliang_mask , @RackMask and @Engineer_Wong etc. https://t.co/VDZSmHLZtC a🧵

A new recombinant, XGA is designated. XGA is a recombinant of XFJ.4, PY.1 and XFG.6. It likely formed by one variant recombines with a recombinant of the other two variants. However due to low sequencing the intermediate recombinant remains undetected. https://t.co/ukInhDCthC

Anecdotally, but, unprompted, the factory foreman mentioned absences are down and wants more. I'm skeptical about sample size/duration but maybe? We had two units go bad, and the workers reported it for replacement, so at least there's no issue with them being unpopular/turned
The very first batch of Nukit Lanterns off the line this month went to protect the workers themselves. We now have Far-UVC in all working and common areas. Nukit is the first company in the world to protect its workers first- so they can protect you, with safe, effective, 222nm

Zimi's own B95-XL (earloop version) has a higher score of 283. Please also note that the exhale valve was manually installed by myself, which apparently didn't break the seal😄 Interestingly, an exhale fan consistently gives me some additional fit factor, reaching 320-350. 4/4

Akkair, gives me a similar score as Rackair, even without headbands, and their latest design is pretty elegant. 3/4

Rackair 8210H, a N95-equivalent, gives me 470 fit factor in normal breathing, and 209 overall. It's slightly lower than 3Ms and Moldexs with a similar price tag, but far more fashionable and beathable. 2/4

I did a few rounds of portacount tests (N99 mode) with Zimi, Akkair and @RackMask . I got an insane 26,300 score while doing the normal breathing exercise on a Zimi 9233 KN100 (Bravo @zhouliang_mask !) The final score of 4,830 (7 exercises) is also very impressive. 1/4

Wow~~~~~~❤️💛
I am so happy that pur Panel (in German) on "The Violence of #Psychologisation: #LongCovid and other postviral illnesses" went well. It consisted of 4 presentations, the first by myself on the epistemological problems of the BPS model and the need for a postviral ethics.

Mockup of how the Tempest Pro works with its VESA mount stacked on an Autopole using off-the-shelf hardware. Nearly silent, massive CADR in a small footprint for events and location work. It should be in the warehouse in about two weeks...

I only use this [respiray+hoodie] trick when I need to unmask and have a meal in a flight where there's partition between me and other passengers. In such settings, a HEPA filter with 13 fit factor is very helpful 5/5

This trick is easy: just wear a hoodie and keep your nose as covered in the hood as possible. 4/5

However, with this trick I can get 10+ fit factor (normal breath only). a fit factor of 13 is certainly less protective than a well fitted respirator, but it could be an excellent extra layer of protection. 3/5

There's an easy trick that significantly improves its performance. I mean, in my hands, without this trick, it gives me ~2.5 fit factor (in normal breath only). 2/5

Respiray is a wearable HEPA filter, which, according to multiple previous tests, provides some protections but not much. Yet I still use it on a regular basis, especially during a flight. 1/5
