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.
That'll help me sleep
I have one. It's not that loud. Even when you are standing right next to it it is easy to have a normal volume conversation.
This looks really cost affordable and efficient, but Iโm not sure my wife will go for the DIY aesthetic.
Beat me to it. I've just been taping high quality filters to the back of my box fan, not as good, but helps in a pinch.
Alternatively, a single Merv-13 filter that's 4 or 5" in depth (20x20x5) taped to the box fan works just as well in a smaller footprint, and still allows you to direct the airflow at someone.
Thanks for the link. Very neat
Does anyone know where I could find some 20-in wide charcoal filter cloth sponge material?
I would like to be able to have my filter reduce odor in the home as well but I can't seem to find anything other than little 4-in strips.
Is 24inch * 100 feet enough?

Edit: They have the foam as well, but it appears to only help against dust particles, not smell. https://duraflowindustries.com/product/381/Duraflow-Filtration-Air-Filter-Foam-Roll-Media-24-x-25-x-6.35mm-(1/4)
Nearly $400 might be a touch out of the price range, but thank you! At least I know that it exists so it's worth keeping on searching.
Haha, I figured but it's the best I could find in the moment.
They have pieces at 16*24 inches, but I couldn't find another that has 21 inch width.
