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?
