I’d like to get one that has widely available filters and would prefer to spend less than $250 as much as I would like a Dyson one. It’s only for an apartment so I don’t think I need something massive but I do live above a busy road.

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.
