I work in Heating, Ventilation, plus A/C service plus this pandemic has been pretty wonderful for business.
I mean I understand the desire for a whole-home filtration system.
Those systems kill plus trap any virus or bacterial germs that are trying to circulate through the Heating, Ventilation, plus A/C system. I also understand the whole-home humidifiers. There is evidence that virus germs dye abruptly in high humidity. Then there are the people who just want HEPA filters or stronger filters installed in their central heating plus air, and what I don’t understand is the pizzerias who want air duct rerouted to the outside, then yes, I do understand the struggle to stay afloat when the government is putting restrictions on everything, my village has laws right now that pizzerias are only allowed to serve outdoor pizzerias. This is because UV light plus fresh air lower your risk of virus exposure. In fact, most whole-home whole-house air purifiers use little UV lights to kill the viruses that pass under it. So do the HEPA filters, for that matter! However, multiple pizzerias are closing in their outdoor dining areas with plywood, plastic sheeting, plus other things. Then they are hiring Heating, Ventilation, plus A/C corporations adore myself and others to come plus reroute Heating, Ventilation, plus A/C air duct so that it cools or heats these “outdoor” areas. So this, essentially, blocks off all fresh air plus UV lighting. No, these outdoor areas are not completely sealed up. That can’t really be achieved with those kinds of materials. However, I don’t see how that is any safer than just eating inside of the pizzeria. At least a few pizzerias are getting the whole-home purification systems installed at the same time. But not multiple of them do.
