Hello /diy/,
please excuse me for the very crude sketch. I intend to jury rig a device that will serve two purposes: humidify air in my room and filter some dust.
I'm more interested in the dust part, increasing humidity is just a bonus. Where i live the air quality is absolutely terrible (particulate-wise), and the apartment i live in is shared by two people, a dog and a cat. Between all that we have a lot dust and that in turn requires a lot of time spent on vaccuuming and wiping shit down so my room looks half presentable. I got used to it but now am thinking if something could be done to make it a little bit easier.
1 would move air, perhaps a computer fan running low rpms so it's quiet
2 would be an enclosure for the potential power and measurement electronics
3 would be cotton sheets submerged in water at the bottom
The way i imagine it cotton would wick the water up and air passing by a large surface area of wet cotton would increase in humidity, while some dust particles would settle on the cotton. The humidity part would be "self-regualting" for obvious reasons, but if the whole things works at all
i would like to add a humidity sensor somewhere else in the room and give myself the ability to set it to a desired level.
Will this work? What would you change?

wouldn't change a thing
looks perfect - just build it as you have it planned
keep us posted on how well it works, anon

Seconded. That sketch and your description match up pretty well with the beast humming away in grandma's living room. My diy gramps built it in 2008. Still works.

If there's animal hair maybe having an initial coarse filter would be good.
Look at what people are doing for air filtering in China. They seem to use big loud fans though.

I would change the air path from that long, serpentine one between sheets to just putting all the sheets in parallel.
It will likely be more effective, especially with a low-pressure blower like a computer fan. You will struggle to get sufficient air flow with the current design without resorting to a centrifugal blower, which will be fairly loud.
Other than that, that's pretty much the basic design for every commercial humidifier.
Watch out for mold, of course.

I'll probably get around to building that in about two weeks, but this thread should still be around by then.

Would this work as well for dedusting though? I want that to be the main effect, increasing humidity is sort of a bonus. Most industrial designs i see exploit the inertia of dust particles by incorporating a number of sharp turns or a centrifuge effect.
Is there something i can add to the water to help with mold?
