I know nothing about your specialty, but I smell the air from the room where I am not cooking flow through from the kitchen. That goes for several houses where I helped out as well. So indeed, no air filter, no airco, can keep the germs from spreading. Best thing is to open all windows and doors and let fresh air in!
Achieving excellence in building ventilation is an appropriate goal for new buildings and for buildings with major renovations. For other buildings, the ROI may not justify the changes.
The best way to avoid avoid metabolic syndrome, related chronic diseases, and Covid is:
1) Eat real food, including plenty of animal-based products and natural oils (like ghee and olive oil).
2) Avoid sugar, corn syrup, and most other natural and artificial sweeteners.
3) Avoid processed foods, especially processed carbs and seed/vegetable oils.
4) Stop snacking and investigate intermittent fasting.
5) Get plenty of fresh air and sunshine, while avoiding sunburn.
6) Exercise moderately.
7) Sleep long enough each night.
8) Find non-drug and non-alcohol stress coping mechanisms that work for you.
9) Pray.
10) Communicate with friends.
These items are proven to have beneficial effects and beneficial side-effects, though they are quite unhealthy for the profits of Big Farma and Big Pharma.
What laypeople will not understand, but need to, is that HVAC effectively worsens the conditions that might promote propagation by increasing aerosolization and then distributing aerosolized particles. It’s not just bad for virions, it’s just poorer air quality all around. The reason the systems are designed the way they are is to conserve heating and cooling energy.
Which brings us to the practical reason why this set of recommendations is absolutely ridiculous. Introducing filters (especially very tight ones) and greater amounts of outside air will mean that the overwhelming majority of systems will need to be replaced. This is because heating and cooling capacity of a system is designed around airflow rates and energy input to accomplish heating and cooling. More filtration reduces flow rate dramatically. More outside air means you need to cool or heat the outside air before it gets introduced to the system, fundamentally increasing energy input (dramatically). Even small amounts of increase in outside air into the mix has huge effect.
Virtually every system in existing buildings will not have sufficient heating or cooling capacity. And that means replacing the big equipment pieces, and likely increasing number of pieces. More condensers, more air handlers, more heat exchangers, more roof top units, it goes on and on.
And the benefit of this for people? Hardly anything. This will just line the pockets of the HVAC manufacturers, the engineers paid to design retrofits, and give the CDC cover in their pretend game to ‘protect public health’.
We get HCQ and IVM taken away as a choice because we don't have RCTs "proving" that they work (even though we do). But masks, forced jabs, lockdowns, and now this. NONE "proven" to work, and quite the opposite.
The latest attempt to bring kids into the fray of this is claiming they are all being subjected to Long Covid. Long Covid which now has so many symptoms you could make it synonymous with "side effects of living."
I am talking to a teacher on twitter who is assuring me there was no panic that stimulated the mitigation techniques employed during the pandemic. When I went through why all the mitigation efforts were ridiculous and ineffective she then spouted the narrative line about how dangerous covid was to children, to teachers, social workers, cafeteria workers...and when I pointed out "there, that is the panic I was talking about" she said I was gaslighting her...which is what she'd been doing when she claimed the mitigation measures were not based on panic.
I'm pretty sure airplanes have a higher air exchange rate than 5/hour being advocated by these rules. And yet, that didn't matter, we were all forced to wear stupid not effective masks in airplanes all the time with abusive power hungry stewardesses to yell at us, or worse.
Hello Again. Interesting article about air flow. As an engineer, and later on in life as an MD, causes me to think differently about various issues. Your article is educational and pertinent. Thanks for the article.
More government overreach. The incompetent CDC is now in the HVAC business? OMG, what will our crazy government do next. I am ready to scream from the government incompetence I see everyday.
Centers for Death and Chaos: Facemask all the fecking buildings so we can get HVAC kickbacks.
Me: Don’t just do something, stand there.
The bigger the fraud, the faker the solutions. The biggest fake being the vaccines. Useless and toxic.

It’s a farce. Don’t believe a bit of it.

Why bother? No one is going back to the office. 😜😜

Hey! Government! How about . . .
YOU will DO NOTHING and WE will be HAPPY!
Why don't they advise ozonation, and UVC irradiation of ducts and ceiling space (above eye level even for tall people)?
Whatever happened to opening windows for fresh air???

quick, check that twitter page that follows Pelosi's husband's investments- whatever HVAC company he invests in, that's the one to buy
