Anything but. They’ve got validated 3rd party studies. Plus they’re a real Hardware product company with a long history of quality product. Not some Silicon Valley “ai magic virus eater”.
>"The test unit was installed in the center of the test chamber with a blade height of 93” from the floor. The test chamber measured 10' x 10' x 10' (3m x 3m x 3m) and a microbial suspension was aspirated into the chamber. Air samples were taken from the test chamber once the unit was turned on, and then at client specified intervals (0, 5, 10, 15, 20, 30, 45, 60, 90 and 120 minutes) over a period of 2 hours and then plated.

A small, sealed chamber were particulates were sprayed into the air once? Test that thing in a restaurant or a hair salon with a dozen people continuously interacting in it and then test the quality of the air
That's not how scientific studies work.
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.

I am mostly concerned about its applicability in places where it'd make a difference compared to other infection controls. Typically when someone comes along with magical unicorn shit, regardless of if it works or not, it's either as a measure to avoid other more inconvenient controls or isn't completely applicable to the scenario it is being applied to.
The FDA was created to fight bogus miracle cures and tainted food.

shrug then they shouldn't mind filing a 510k [1].
