Has anyone tried making a PAPR or HEPA stroller? A few people have mentioned the concept but the only source I've found is this one paper: https://www.researchsquare.com/article/rs-2430680/v1 I'd love practical tips. Right now I can't go into stores with my baby because she can't mask, having the ability to wheel her inside would greatly expand what I can do while caring for my child. Also useful during wildfire smoke. #CovidIsNotOver #COVIDisAirborne #strollers #PAPR #HEPA #AirFiltration #babies #pollution #smoke

@skyfaller@jawns.club the last I read about it was the paper you linked. Naomi Wu and Michael Hoerger were the only ones I saw posting about purifying the air for babies in strollers on Twitter or anywhere else. https://mas.to/@fritzoids/111248951269035137 and https://mas.to/@fritzoids/111249085161154824 The link to the Korean babycarrier has detailed photos and measurements if you keep scrolling down... you could have someone make one for you?

@skyfaller@jawns.club the specific pump mentioned in that link: Trudsafe Powered Air Pump for Respirator ($110 each) I seem to recall FitTestMyPlanet testing the Trudsafe and finding it leaked with fit factor of about 5 (bad), I can't find the link. CriticalAerosol followed this up and found similar. https://xcancel.com/CriticalAerosol/status/1670544219738628096 I remember there were others trying to fix the Trudsafe leaks, I can't really search Xitter externally, and I don't know what developments may have happened since then. Either way, I feel obligated to mention possible limitations of the Trudsafe. The link evaluated CADR and SPL, but not fit factor, trusting that the pump wasn't leaking. I recall some people recommending the Ford PAPR instead, quite a jump in price, but again this is two/three years ago. Are people still scoring government surplus PAPR for pennies?
