AirBoss Defense PAPR
First remove the accessory tips from the air duster, and the top of the snorkel from the nose mask Gorilla tape, air duster, exhale valve & nose mask
Carefully cut a hole in the bottom of the nose mask to install the exhale valve that relieves excess pressure for comfort, the raised circle is exactly the right size so that’s your cut line Exhale valve installed
Apply a ring of hot glue to the end of the air duster and push the Moldex filter against it, wait for the glue to dry then apply a bead of glue all around the joint, you can apply hot glue to the seams of the duster if desired but I didn’t notice any significant difference after Moldex P100 filter glued to the end of the air duster and hot glue all over the seams
Apply two long strips of the Gorilla tape from the air duster body to the snorkel on the top and bottom, then wrap the joint several times to seal Taping the air duster to the nose mask
Remove the plastic frame from a Zimi 95S and cover the Moldex P100 95S over Moldex P100
Charge the battery and it’s ready to use, speed 1 is plenty fast and will give 45-60 minutes run time Dental PAPR in use
Practice nose breathing with your mouth open before you go to the dentist

Using a Dental PAPR or other nose mask option at the dentist doesn’t guarantee safety from infection, but it does lower your risk

I'm going to be a bit vulnerable in this thread, which is for the people who care & have been failed by public health. I care deeply about people, and it saddens me to see masks with an apparent poor fit, especially when I know the person is trying their best to stay safe 1/12 PMM at the tools table Clean Air Panel
It almost physically hurts me to see it, and I either have to look away or try to help. When I try to help, I’m just trying to share information & sometimes I get misinterpreted as trying to police people 😭 This is not my intent at all, people don’t know what they don’t know 2/
Let me be clear; the problem is public health, which has not communicated accurate information about airborne virus spread and proper fit testing of PPE - which they KNOW about, but refuse to share resources in a clear & accessible way for the public. 3/

Please note I have not yet conducted a fit test with these, but on a well fitted elastomeric respirator I don’t expect much change with these thin headphone covers, they fit both 3M and Honeywell pancake filters well
Assorted colors here amzn.to/3FTlixsPurple cover on a 3M 2291 on a OmniMask
Colors for your pancake and cartridge filters Ocean Green Red Army Blue Gray City Bordeaux Purple Pink Black
Fits the Honeywell P100+OV cartridge filters acceptably also HM500 Series with source control and purple covers

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 Showing how to shape a nose wire before putting a mask on
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 N99 mode Fit Factor 9.2
N99 mode Fit Factor 122
And here’s my results with a bifold KN95 ear loop, even with the nose wire shaped well, I still failed, but the mask is much more protective, N99 mode Fit Factor 1.1 for the pointy nose wire and N99 mode Fit Factor 6.6 with the nose wire shaped, just 2 minutes quick test to show N99 mode Fit Factor 1.1
N99 mode Fit Factor 6.6

Here’s a video showing how to use clear tape, an EPDM band and MERV13 filter fabric to make a 4 square foot filter for an HVAC vent

Aff link for MERV13 fabric amzn.to/4f2fFsw

Finished vent inflated by air
Small HVAC vent filters don’t have enough surface area and as a result either don’t have enough filtration or add too much air resistance, this gives the surface area, in the video I’m using 4 square feet of filter fabric
Both 3M clear packing tape and Gorilla Glue Crystal Clear tape stick well to the MERV13 for this

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

The discontinued Honeywell PAPR I have
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
