I think none of the HEPA filters are effective with any sort of virus, since the virus particle are smaller that dust particles...
but that you should ask to the manufacturer!

The problem with these masks is that they only filter air taken in for the wearer, they have no outbound filtration and therefore may pose a risk to others if you are Covid positive.

I would certainly not recommend wearing masks such as these around vulnerable people if you are not testing daily to ensure you are virus free.
