Viruses are 10 to 100 times smaller than bacteria and consist of nucleic acids (DNA or RNA) enclosed inside a coating of protein. They are unable to reproduce on their own.  Viruses are only able to reproduce by entering cells of a bacterium, animal, or plant and utilizing the metabolic system of that host organism.

80% of known viruses have glycoprotein envelope shells which enclose the inner nucleic acids and proteins. S- Protein spikes in these envelopes allow viruses to invade the host organisms. 
If the viral envelope is broken down, the virus becomes unable to invade the host cell, but rather gets absorbed by it, essentially losing its functionality. This is known as viral inactivation.
Through its unique action, the enzyme immobilized on the filter media dissolves viral envelopes, and thereby render theoretically all envelope viruses inert.

The other 20% are non-envelope viruses, which the enzyme filter is not effective to inactivate. However, due to the antibacterial function, no host microorganisms can survive on the filtration media surfaces, and viruses are unable to proliferate (effective inactivation).

Enzyme Filters been tested and shown to be effective in inactivating the following viruses:

Orthomyxovirus Influenza Virus A
Orthomyxovirus Influenza Virus B
Paramyxovirus Parainfluenza Virus
Herpes Herpes Simplex Virus(HSV)
