    I think air scrubbers are for more intensive situations, like cleaning a flood damaged home, or painting things, since they’ve got chemical filters and UV sterilizers in them. Air washers are mostly just air filters that rely on water to trap stuff first and foremost, one I saw was just a series of spinning disk’s half submerged in water. Surface tension caused water to stick to the disks, and a fan blew air between them, so anything in the air would get caught and pulled down into the water tray.

    The other function they serve is passive humidifiers, as air passes over the water it evaporates, but only if the air is capable of holding the water. If it’s already humid no evaporation occurs, so you don’t get things like condensation that you’ll see with active humidifiers that aerosolise water.

    You can diy one by hanging up a towel, having the bottom touching a container of water, and pointing a fan at it, and capillary action will draw the water up into the towel. So with one of these boxes with cotton filters, would serve the same purpose.

    I’ve been wondering if you could make a hybrid of this and an air washer, replacing the filters with a frame and cotton sheets and then putting it in a shallow tub of water.

    I know some air filters are made of cotton to begin with, if they’re already in a plastic frame you could use that as-is.
