alt Hacker NewsAir there any air filtration systems that use water (maybe by bubbling air through water or a fine mist) to remove particulates? Like a canister vacuum cleaner, I'd love to be able to see the dirt/dust/particulates/gunk that is being removed from the air.
It's a pretty common method in industry (a wet scrubber) but I don't know of any indoor-scale, self-contained units - it sounds like a recipe for mould because a misting one would basically be a humidifier too, and they are hard to maintain because bacteria like legionella can grow in the water and then you're dispersing it inside your house!
