To confirm this, we completed viral penetration tests to the ASTM F-1671 standard for our membrane materials. This is a standard test for medical garments, gloves, and gowns. This test uses a viral substitute (bacteriophage ΦX174) to measure transfer of particles in a liquid under pressure though a material [4]. The ΦX174 particle is ~25 nm in diameter, which is much smaller than an individual corona virus particle. For both our Mx4 ‘T4’ and HP ‘Gryphon’ membranes, no transfer of viral surrogates were observed in the ASTM F-1671 test, confirming that our membrane materials act as a viral barrier.
