The device you linked detects specific VOCs, not viruses or even proteins. I don't believe this would be appropriate for infection detection. Or at least not a specific infection detection without a known baseline.
The cost also seems suspicious. Every patient needs their own mask - you can't reuse those. Also, with the 4 cartridges per test, as recommended, that's unlikely to be $0.
FTR: Current coronavirus testing uses either an RNA match from a saliva sample, or a specific antibody reaction test - both are very specific to that single virus.
