That test procedure sounds similar to the standard test for CADR (ANSI/AHAM AC-1-2015), which uses a 1008 square foot test chamber and measures the ability of an air purifier to deliver clean air.
CADR is the product of air flow and fractional removal efficiency, and it's the industry standard value if you want to compare performance of one air purifier to another. The CADR test usually makes separate measurements for dust, pollen, and smoke (particulates). It looks like they adapted the normal test procedure to measure the reduction in live/viable microbes.
However, in a few minutes of looking at their homepage I don't see anywhere they list a number in CFM of purified air, which is what CADR measures.
