The classic box fan CR-Box was invented during the COVID-19
pandemic and is THE most cost effective method to clean the
air. They have
been shown
to be remarkably effective and outperforming most commercial
HEPA filters on the market. It can also be scaled up as
there have been many CR box builds where entire schools came
together to provide one per classroom.
This article is legitimately helpful, but I'm mostly posting it
because I find it extremely amusing that (at least as of a year ago)
the best-in-class air filter by cost and among the best overall is
literally just taping a bunch of filters to a box fan yourself.
Hilarious and easy on your wallet! But what's even funnier
is Joey's #1 recommendation:
The PC fan CR box was a recent invention to find a method to
achieve high clean air delivery rates with very low noise.
Noise is the greatest limitation of in-room air cleaners and
PC fans are the best option to address it. There are no
other air cleaners on the market that have the capability to
supply 150 lps of clean air at 35 dBA.
Nothing comes close.
The only thing better than than taping a bunch of filters to a box
fan? Taping them to a bunch of PC fans instead! Granted the ones
linked here are a little more sophisticated than that, but
elsewhere on his site Joey presents one that absolutely is just fans
and tape:

The longer we tolerate the little lies that robots tell us,
the bigger the lies become, and the more difficult it becomes
to untangle them from our everyday lives. This is not an
inevitability, however; we can find in ourselves and in our
connections with eachother the self-confidence to learn how
these things work, to unpick the threads, to see…
