Reddit mentions of GE Whatman 1841-090 Multigrade Glass Micro Fiber Filter Paper without Binder, Grade GMF 150, Circle, 1µm Pore Size, 90mm Diameter (Pack of 20)

I think you're right, it will be somewhere around a grand for the kit I'm planning...but because I'm growing at home, it's basically a one shot cost (minus alcohol and filtration media,) plus I'll get awesome product, at least as good as the stuff I can buy in the Recreational dispensaries, and better than anything I could get from the black market.
I am in a legal state, but good quality wax is STUPID expensive, over $100/g plus I'm growing the flower myself (so the "expensive" part of this is actually something I already have on hand.) I grew more than 4 pounds last year legally in my living room in a 8x4 tent.

I'm staying away from butane because I'm doing this in my condo in my living room and not in a real lab. If I had fume hoods, and a fire prevention system that didn't involve me holding a fire extinguisher, then I would be there. I did originally look at butane columns, and I totally could go that route...I just didn't like the safety aspect when combined with my condo as a location.

I am going to use a vacuum kit with one of THESE plugged into a 2000 ML erlenmeyer flask with the same 24/40 glass fitting between them. There will be a vacuum pump attached to the side inlet to generate suction.

I'll use THISfilter paper at the bottom, then like half an inch of diatomaceous earth above that for filter medium.

The alcohol and the activated charcoal will be poured carefully into the top, and then it will strain itself out.

I figure 1 or 2 passes and it will remove all of the charcoal (I've read 1 but I'm skeptical) with an approximately 9-12% loss factor (by weight) compared to the initial extract, but the polished extract should be chlorophyll free, and it should be a beautiful honeyed color.

I also bought one of THESE and one of THESE so if I am unhappy with the results from my column, I have a final "stupid fucking fine" filter that I can pass the ethanol extraction through. This will give me a final filtration of 0.2 microns, although due to the added cost to each batch, I'm hoping that I don't have to go this route. I suspect that the filter plate on this will clog very quickly, which is why I'm hoping to use diatomaceous earth as my "primary" filter medium. It is both very cheap and incredibly effective.

Because I'm doing this with my own weed (rather than trim) and I'm doing it in pretty small batches (I'm not selling this stuff...) I'm hoping that the source turbo, even though it's small, will do what I need it to.
