He recommended I buy it myself on amazon and linked me to a youtube to install it: https://www.iwaveair.com/products/iwave-r
He said that his company would install it, but they'd overcharge and it is easy for anyone to install themselves. He had one in his house and told me all about it like a sales pitch. I installed one not because of the coronavirus, but because it helps with particulates in the air such as pollen and dander, which absolutely wreck me. I've only had it for a year, but it does seem to be noticeably better allergy-wise.
That's a good thing, because there is no safe/acceptable level of ozone in indoor air:

Ionizing can be a great way to remove fine particulate from the air, but it works best when there are charged surfaces for the charged particles to plate-out on. Simply ionizing them in the ductwork means the particles stick to whatever's handy, which may be the ducts, may be the furniture, may be your lungs.
Which is to say, this product uses a lot of the right vocabulary, to describe precisely the wrong engineering.

Do read the warning from the EPA.
We are, of course, talking about miniaturizing a Direct Air CO2 capture system, which usually operates at large scale to get efficiency. Replaceable cartridges that are regenerated at a central location may be a better option.
But oxygen concentrators are small and cheap and portable and don’t require much energy to operate.
At 1400ppm CO2, we've turned what, 1000ppm O2 into CO2 (is it 1-1?), or 1% of the atmosphere. Dropping O2 from (Edit: Fixed numbers) 21% to 20%. Or about a 5% reduction in O2 density. Equivalent to approximately 1500 feet of elevation... That's just not that much.
(There's also a long list of papers showing issues with CO2 toxicity at low levels of CO2... I keep intending to write a blog post summarizing them)
So all the standards and codes are designed around reducing unnecessary ventilation and frankly, there's been very little consideration of the health implications until COVID hit.
On the HVAC side, you want a system with a high CoP and I'd probably be looking at some form of energy recovery on the ventilation side.
I installed it, and would never go back to forced air. For some reason, it's not popular on the west coast.
It's so simple, a DIY'er could do the instal.
My energy bill is down, and allergies are better.
(I've noticed every store I have been in has forced HVAC, and I have a weird feeling forced air spread viruses. Plus--most retail stores have old systems. They might have slapped in some high mir filters, but I doubt they help with anything on old leaky systems.
(To those interested in hydronic heating, buy Modern Hydronics, by Stegenthal? I'm too lazy to look up his last name, but his book is used as text books.
