depends how good you are with your tools. brainstorm, come up with some ideas, walk around the hardware store.. once you have a plan in your head, buy the parts, go home, and put it together. I made my carbon filter out of wood mostly, box shape, but carbon costs a lot to keep it going.BC Northern Lights attach these short carbon filters to the outside of their cabinets and I would love to either buy one or make it. Is it possible?
Thanks in advance!
