If looks dont matter, I'll recommend the same thing I always do when people want an air purifier.
Look into making a Corsi Rosenthal Box. They're surprisingly effective, and dirt cheap.
It's not just about aesthetics. That DIY box will be loud as hell.
As mentioned in the article these can be quieter than a retail unit. The large fans move a lot of air and the large filter area means it's easier to pull that air through; both combined mean a lower fan speed is needed for a given throughput.
They can be. Because of course there are poorly made commercial units that are only quiet because they have low CADR. But you'll never be able to get a DIY box as quiet as a well made unit, unless you basically engineer your own air purifier device, use blower motors, etc., but that's not a Corsi-Rosenthal Box.
