    1. David Fisman. (2021, December 15). HEPA air cleaners in hospital...lets compare cost to ECMO. ECMO course in the US costs around $93,000 CDN; US cost:charge ratio is around 0.2, so let’s say that’s $20,000 CDN. That’s the cost of 50 high end hepa air cleaners! Or you could do 250 CR boxes at around $80 a pop. [Tweet]. @DFisman. https://twitter.com/DFisman/status/1471259305961828355
