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.

    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.

      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.

      It’s not just about aesthetics. That DIY box will be loud as hell.

        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.

        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.

      This looks really cost affordable and efficient, but I’m 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.
