#32This smells of magic unicorn shit to me.
Anything but. They’ve got validated 3rd party studies. Plus they’re a real Hardware product company with a long history of quality product. Not some Silicon Valley “ai magic virus eater”.
Those 3rd party studies seem like a pretty big joke
>"The test unit was installed in the center of the test chamber with a blade height of 93” from the floor. The test chamber measured 10' x 10' x 10' (3m x 3m x 3m) and a microbial suspension was aspirated into the chamber. Air samples were taken from the test chamber once the unit was turned on, and then at client specified intervals (0, 5, 10, 15, 20, 30, 45, 60, 90 and 120 minutes) over a period of 2 hours and then plated.

A small, sealed chamber were particulates were sprayed into the air once? Test that thing in a restaurant or a hair salon with a dozen people continuously interacting in it and then test the quality of the air

#33If this works, it seems like a short-term substitute for retrofitting buildings with proper fresh air ventilation systems.

#34We’ve got a beautiful newish library in downtown Austin, and they use Big Ass Fans in a number of the outdoor spaces, balconies, patios, etc., including the enclosed balcony in the children’s wing, with the brand name clearly legible on the fans. While it’s not something that bothers me, I do always wonder whether and how often they get complaints from parents about the word “ass” being there for children to potentia…
Big Ass is based in my hometown, and I've had a few friends who've worked there. They absolutely get a lot of complaints about the name and actively taunt people who are offended by it [1] Apparently they do have models without the logo that can get used in churches and schools, though.

Ionizer--probably unicorn shit. The UV-C one? Probably real--and note it's the one labeled as "Verified by third parties". Moving air at some reasonable rate past a strong UV-C source really will sterilize it against a lot of stuff.
But isn't that boring old tech which is easily replicated in a DIY project, or copied by competitors? What makes it special?

#36A german Max Planck institute is working on a DIY system for schools that will get rid of 90% of aerosols. It costs less than 200€ to build out of easily available parts.

Isn't a big ass fan just boring old tech which is easily replicated ...?
Just because something is easily replicated doesn't mean I want to spend the time doing it.
And, as a side note, I suspect you underestimate the engineering behind those fans. Making a large fan which doesn't vibrate or make annoying noise is non-trivial.
Re: Big Ass Fan’s Clean Air System
#38Is that a UV-C bulb just exposed to the site above the fan? That doesn't seem safe.
Seems like they just reflect all the UV from the bulb up and are counting on the ceiling not reflecting a harmful amount. With the right ceiling material that could actually be a pretty good idea.
I wonder how one can test if the amount of UV light reflected from the surface is dangerous? Alternatively, determine what is the percentage of the UV light absorbed?

#39Would "Ion Technology" mean electrostatic disinfection?
It seems to be UV.

Ok, I agree, but a similar thing can be said about vacuum cleaners, coffeemakers, washing machines, ... you get the point.
