Where does air pollution come from?

For those who are worried about indoor air pollution like me, I found out thanks to this [dynomight post](https://dynomight.net/ikea-purifier/) that having an efficient air purifier is a low bar and is actually quite accessible to poor people like me !

Even cheaper is the DIY Corsi-Rosenthal box. We make a couple every few months and it does make a huge difference! Worked wonders during the wildfires a couple of years ago

I ended up purchasing a Lasko Air Flex[1]. It fits standard HVAC filters. It doubles as a white noise machine for me, it is quite loud. This review[2] indicates it works well but a bit power hungry, and it definitely gathered a visible amount of dust over a 1 year period.

Standard filters is interesting but it looks that the Ikea one has many advantages: it's smaller, discreet, less power-hungry, has textile pre-filter so that you filter will work longer, can accommodate activated charcoal filter and is not loud on 1

Air 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!

Even better is a computer fan based cr box. Quieter, lower TCO etc.
