Ended-up building a PLC based system. Its been rock solid reliable & I can do pretty much anything I can imagine with it. Its a little risky, in that if I ever need to sell I've limited potentional buyers. But, I think thats the case with just about any centralized system. Not long after I looked at a lutron system, the local lutron tech passed away. One house under construction using lutron was brought to a dead standstill. AFAIK, there are no nearby lutron programmers to this day.
However, PLCs are easy to obtain, relatively easy to learn (if you're technical) and just about any small+ city is likely to have control engineers that might be willing to support as a side hussle.
Not related to ventilation, but I found the Trompe compressor to be an interesting example of forgotten technology
The trick is that the box fan turns over the air much faster than a conventional hepa.

Still, $10 for the ikea filter seems like a good deal if you get good life out of it. 20x20x2 at filterbuy is about $16.5 x4.
I don't know how many times I've been in a group setting where someone said, "I wonder who came up with that great idea" seemingly oblivious
and yet, NTs seem to give credit to each other for simply being in the same room together

I believe age 18 came about because of the Vietnam War draft. Old enough to die; old enough to vote & drink. Something to consider.
The tax system is a problem also. There's an agency issue; it all about getting someone else to pay more taxes. Don't want to open that can of worms now.
Its always us vs them.
