    Hi, I'm new to soldering and I certainly don't like fumes that comes out when soldering. These smells give me a headache for the rest of a day. But the commercial extractors was too expensive for me. So I decided to make a fume extractor myself.

    I chose to do it with a 80 mm 3000 rpm computer fan. But which filter should I use?
    Do I need a activated carbon filter made for fume extraction or can I use fish tank filter sponge?
    And would car filters work too?
    Lastly, will these filters be able to filter out smells of soldering fumes too?

    Thanks, Tyler.

    Most of them have a fan + sponge. I don't think a 3000 rpm fan has enough force to push air trough a heavy duty filter. Either build a simple one with a sponge or get a stronger fan. Faster =/= stronger.

    To filter the smell, is there a window? Just open the window and let air mix.

    If you're in a windowless room, you can create a positive pressure room, then let the fumes flow outside.

    In any case, good luck.
