Never ceases to stump me that we have the technology to kill 99.95% of airborne viruses, proven to work, non-invasive, cheap to deploy and install, and is produced at scale already and we just like - collectively - kind of just don't really use it.
HEPA-grade air filtration is proven, cheap, and makes everyone's lives strictly better. It, like, makes zero fiscal sense for governments not to mandate its use in all covered public spaces ASAP.
We don't mandate HEPA filters because it's a massive cost and doesn't actually stop virus spread in itself.
Nano particle level filtration is insanely expensive and you'd need to change the air completely every few minutes to even have a chance to make a dent at all.
@WagesOf ah right, yeah I agree that perfect should be the enemy of good.
Perfect filtration sure takes effort, but the point is not perfection — it’s reduction. Like, I can go to IKEA today and buy a HEPA-grade filter for $6. Not best in class, but certainly affordable. Why? Because they’re produced at scale.
“To make any dent at all” is unsubstantiated by evidence. It’s clear that any amount of ventilation is better than none. Any amount of filtration is better than none.
@yosh I'd rather use something like the REME Halo which will even take out the stuff that the HEPA filter fails to capture. One of the problems with HEPA filters is the airflow reduction. Tons of places cannot install HEPA filters because their ducts are too small as you need an increased surface area to ensure the airflow isn't restricted. So that's $$$$$$$$$ vs installing something like this which does the work with UV (and some patented magic)
I installed one of these in my condo just before COVID hit and it was amazing. Within an hour the air in my condo lost all its "old home / carpet / pet" smells. I never got COVID once while living there. Brilliant tech. (UV light on titanium dioxide == airborne peroxides)
I know no good sentence starts with this, but: I'm not a conspiracy theorist, but maybe someone took a long hard and psychopathic look at the demographic projections ...?
