HVAC vs. Localized Sanitization
Sadly, this is just one example confirming the challenges posed by indoor air. Many people have discussed the ASHRAE recommendation of 7 air exchanges an hour but keep in mind that's for the HVAC system and sadly it looks like in the course of even the first air exchange, the virus was carried across the room to another customer's personal space or "bubble".
Can't see a more graphic example of the need for supplemental, localized air treatment to try and inactivate the pathogen before it spreads inside the restaurant, office, classroom etc.
Let's not confuse local, on-the-spot air treatment with building wide air exchanges. Both are very necessary. Checkout our "FRESH" simple UVC Air Sanitizing Solution.
