This tutorial and method actually worked and it worked well.
Earlier this year the filter core stopped working in my second hand MSR Miniworks Filter Kit, Thing. It seems pretty much impossible to find a non-carbon MSR Miniworks filter core online these days. I think it is time to move on to a different brand and a modern equivalent (also time update a lot of information in the Lava Library too).
Does anyone know of a good non-carbon filter that can safety filter the fluid in lava lamps, Please & Thank You?
