    Which in reverse makes it dangerous to get a cheap ones that sound like the real deal. It is hard to tell if the filtering components used are quality or not if you are not an expert. That´s the caveat here. Nothing is worst than feeling save, while you are not. The price of purchasing is also not the only thing you should keep in mind. Those filters need maintenance and you need to get replacements from time to time. Also you need to know when these filters need a replacement. To early and it is even more expensive. To late and you inhaled the fumes for weeks or months.

    That is why I did not mentioning filtering solutions in my first post. A proper way to dump the air to the outside is the safest and most cost effective method, when done right.

        I forgot to mention something truly on topic: I am not bothered by odor from PLA, but I do sense something, not exactly an odor, but something, from PETG. My head feels a little 'funny', and my nose is mildly irritated. I'm hoping my carbon furnace filter will alleviate it.

          Today I constructed the carboard filter box I mentioned earlier. I dug out a 140mm 12V fan and a 9V AC adapter. I decided I wanted a way to disconnect the AC adapter from the fan/filter box. I don't have any barrel jacks so I looked around to find some way to create a wall jack I could install on the box. Since I've done so much Ethernet work over the years, I have quite a stock of RJ45 connectors & wall jacks, plus the tools to work them. I decided I would replace the default connector on the fan's wires with an RJ45 jack, and mount that on the box. I would also replace the barrel connector on the AC adapter's wire with an RJ45 plug.

          I would attach the fan and RJ45 wall jack to 1 side of the box, and the furnace filter to the opposite side. All of the edges and corners would be sealed with packing tape.

          So....

          Here's a photo of the side of the box with the fan and RJ45 wall jack:

          Here's a closeup of the fan and wall jack. I plan to design & 3D print a grill to cover the fan:

          And finally, here's a closeup shot of the edge of the filter, in case anyone wants to buy the same kind.

          All in all, this filter box cost me only the price of the furnace filter. This is, after all, simply a proof of concept. Can an activated carbon furnace filter be used to remove filament fumes from the air? If it works, how well? I guess the next few days to weeks will provide an answer; at least I hope it will.

            Normally (what is normal) I keep my printer working like a slave because I have this strange desire to fill the world with all the plastic crap I make. Same room, very small and I love to stand over it and breathe in the fumes. I'm not really sure there are any, except when I burn out plastic from a plugged nozzle on my electric stove. And that isn't very bad. PLA of course. I do open the window in this case.

              Ender5r does seem to have a good idea for toxic fumes. I don't play with them. I do know what they can do.
