Best material for diffusing moisture into a closed vessel?

  1. Nov 5, 2015 #1
    Anyone have any suggestions on other [mold-proof] materials that might be good to diffuse moisture (distilled water) into a vessel?

    For a project, I am trying to create a re-humidification vessel to re-humidify certain materials that have dried out, and am trying to think of the best material that A) Requires no batteries or moving parts and B) Won't succumb to mold.

    Here are some of the things I've tried and some ideas:

    The most natural thing that comes to mind is simply dipping those wooden reed diffusers that are used to diffuse scents, into a glass of water, and keeping it in the vessel... though it seems to be on the slow side in diffusing moisture (relatively low surface area).

    I've tried folding over a paper towel in origami-like fashion, and then dipping one side into a glass of water and leaving it in the closed vessel. That diffused moisture very rapidly, but developed mold as well after a few days.

    The next thing I'm thinking of trying is getting a flat piece of reed (like those used to play clarinet, for example) and using a few of those. Larger surface area, and natural mold-proof construction. Just might be on the expensive side to buy a bunch of those clarinet reeds, and they are short, lowering surface area.


    Any suggestions on mold-proof materials for diffusing moisture, or perhaps how to make this project better? I can post pictures if need be.

    Many thanks!

    Welcome to the PF.

    If you disinfect all of the surfaces of everything before starting the process, and use sterile water (or maybe distilled water), do you still get mold?
