MADA Spirometry Filters:

MADA filters have been tested with MS-2 Virus (with a size of 0.02 microns) at a flow rate of 750 liters/minute for a "continuous time" of 5 minutes.

That's why we achieved a Filtration Efficiency test result of 99.94%. (tested: HPA PD CAMR Porton Down UK).

The new coronavirus has a variable size ranging from 0.08 to 0.16 microns (like most viruses that cause influenza).
It means that the size of the coronavirus is 4 to 8 times larger than the size of the "testing" virus we used (MS-2).
Assuming what is stated above, we can mention that our filters are able to eliminate (possibly more than the indicated result of 99.94%) any possible risk of "cross-contamination" by the new coronavirus (patient -> device / spirometer - * next patient and environment)'.
