In 2025 lets normalize shaping nose wires well before donning a mask, I’m positive this will improve protection, getting the best performance out of your PPE is important because we know prevention is key

Do the final adjustments after putting it on, but this is important first
Here’s my results for the Kid95, bifold headstrap mask with a chin staple, 9.2 N99 mode Fit Factor with a pointy nose wire and 122 N99 mode Fit Factor with a properly shaped nose wire

DIY pandemic, surgery in the lowest COVID risk possible way, with a $100 PAPR

The OR was mostly surgical masks, not N95s, but my PAPR never came off which’s only an option if it’s a surgery that can be performed without intubation, I had to fight for that
ebay.com/itm/2045750617…
The Honeywell PAPR shown in the previous tweet is now discontinued, but the AirBoss PAPR new in box is still available at the link for $100, just don’t buy it if you live above 4,000ft and you definitely can’t use it on a plane

Ok, help me out here, what are the ways to describe a person who says they will do something, but then doesn’t and upon follow up now refuses to do what that said? Multiple people have tried to intervene with no success so all that’s left is twitter public opinion court Al all volunteer community project requires trust and communication to function, notwithstanding the muddled privacy policy with @FitTestMyPlanet ‘s project, he said he would delete my data almost 4 weeks ago, as he has done for others who left his project, but now he will not

Here’s my thread of top tips to get the best protection from your mask

First, if you have facial hair, shave every day, the part of your face where the mask seal sits needs to be clean shaven

If you aren’t willing or able to do that see the end of this thread for otherideas For masks with nose wires, form the wire to the shape of your nose bridge, no sharp creases

Building a DIY dental PAPR for the @covidsafeco loaner library I’m attempting this build with a cheaper air blower, if it passes on the PortaCount I’ll share the model, making this affordable to more people, if not I’ll return it and buy the one I know works and rebuild

Update to my Dental PAPR build, I’ve tried every brand of filter on here and Moldex P100 filters with a Zimi 95S as a prefilter is giving the best fit factors

Also the Moldex filters are pleated and don’t collapse under the airflow so the spiral thing isn’t needed

Parents and adults with small faces, this is a draft chart comparing the sizes of small masks, feedback on the relative sizes of these masks or others similar in size would be appreciated

The smallest disposable masks ordered from extra small to small by vertical height, but because fit is a 3D problem some of these masks will fit a range of face sizes and others only a very narrow size range, all the ear loops will seal better with the Bone Lanyard, see Alt text This bone lanyard stays put at the crown of your head and allows the tension to be adjusted for the top of the ear loop attachment vs the bottom by adjusting where on the ear loop the lanyard is attached, my favorite ear saver amzn.to/4drfmaU

I’m going for Novavax dose 2 tomorrow so I’ll be describing my experience & preparation, which is not a recommendation for anyone else my preparation starts today with cutting my carbs to 100g total for the day All the medications on the left I will take prior to starting the rapid desensitization process of Novavax, the ones on the right are in case of an anaphylactic reaction

NIOSH fit panels are designed with a bias towards adult Caucasian males which means those who don’t fit within that demographic have a lot smaller selection of options, unfortunately that includes all children at some point in their growth, thread on mask options for small faces For disposable masks, from smallest to largest but still small SaveWo Bear Infants, Lutema M94K Extra Small, WellBefore Kids3D X-Small, Trident XS, SaveWo Small, Halyard Small duckbill, CanadaMasq Q100 XS, SR9520S, Can99e Kids, Kid95, BreatheTeq XS, Trident Small

People with narrow faces and a hard time fitting masks, try bringing the chin together at an angle for stapling and then if that causes the nose portion to pull away from your face try attaching the top strap closer to the nose wire, I like to use staples reinforced with hot glue

Now that I know the two modifications I need to make it’s easy to apply this to multiple models, I still fail some of them but the fit factor always improves when I do this

Here’s pictures for my Dental PAPR build





Here’s photos of the assembled dental PAPR and a photo of it in use at the dentist

Unfortunately the internal battery only lasts 55 minutes on Low, which is plenty powerful enough, and it will not run while plugged in, so not helpful for a longer appointment

Here’s a thread of tools to support cognitive rest while reducing boredom, not all of these will be suitable for each person, test with a short use and if it’s too stimulating or causes a crash after don’t keep using it
1 is a low voltage fidget

So my local Facebook groups are full of chickenpox for the second time, hand foot and mouth disease, and a weird rubella like rash virus. The one thing they are all sure of is that it cannot possibly be monkeypox, because they are not a man who has sex with other men Tools to protect yourself from COVID, Monkeypox, and everything else-

Small face elastomeric respirators.
I have a full face respirator that fits great. I’ve been using an MCU-2/P for 15+ yrs. Since COVID started I’ve been trying to find a half face option. ACI Duckbill N95s are the only disposable N95 I’ve tried that fits.
Now respirators 🧵 3M 6100 was the first one I tried. I could not pass a user seal check for negative or positive pressure despite many attempts. Very painful due to narrow nose bridge at the top.
