1/21 What am I up to? Just testing 5 PAPRs against each other as is normal. All of these offer a high level of protection except one. Highly relevant to the #PAPRbuggy #pramPAPR #PAPR 
2/21 As I have posted before some of the tests NIOSH performs on these is to make sure the air flow stays at 170lpm to maintain positive pressure and a filter test to see that it is 99.97% efficient. I have confirmed all of these stay at 170lpm with included air flow testers.

Kids <2 yrs old can’t mask.
Kids <6 months can’t vax.
Many parents are using strollers w/rain covers to try to get some protection during essential activities.
Does adding a #PAPR or #HEPA device help?
I tried 6 models: engrxiv.org/preprint/view/…

First off, thanks @RealSexyCyborg for the original design. Thanks to @ccwake1, @gjmf, @drgregkelly for ideas too. Happy to acknowledge!
My goal was to test 6 models & help relate them to non-engineers.

The PAPR & HEPA buggies I tested had an estimated 57-951 air changes per hour (ACH) in these TINY spaces. The worst design had about 3x the air cleaning of an OR.
You can make a #PAPRbuggy that’s super discrete for about $110 more than an existing stroller & rain cover.
