• I just received marketing material from a company that claims installing new AtmosAir purifiers in their premises will kill 99.9% of all airborn viruses. How credible is this?

  • Not implausible for an HVAC system, but it does only apply to air passing through the unit and does nothing for direct person-to-person or surface contamination, so whether it's any bloody use is another question.

  • 99.9 percent of viruses as in up to 99 of a list of 100 more common viruses. Not 99.9 percent of viral gubbins in your office/house/boat.

    Decoding marketing bullshit is a dubious gift. Why couldn’t I be 7w/kg instead :(
