It can't be avoided. Something like this can help cut down on it though. You can make a funnel with it and just let it drip into a glass. You can sometimes find a good price on better paper, but it's rare. I wouldn't go less than 1.5 microns though. I use this paper in an Aeropress first to squeeze the tob, then filter with some better paper I have, but this paper would be good enough. also, the description says 10, but its a pack of 100.

I just picked up a filtration set yesterday. Haven't put a run through but I figured you might like to have the links together. Funnel, Pump, filters.

These are the ones that I use.

I've read for vanilla pods that you want to filter it a TON but I'm not sure why exactly? maybe sugar related? Just remember seeing talk on ECF of using as little as 1-1.5 micron for vanilla bean extractions but it might just be someone trying to get a cleaner concentrate.

Without a vacuum set up, I think you might be able to get it to filter through as low as a 1.5 micron filter however, could probably just do a 2.5 and be just fine.

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.

I've done it a few times so far on my DE1. I'm not sure how effective it would be on a different machine, but I suppose the blooming/precise program might be a different benefit from the filtering.


I use these filters based on someone else's recommendation here. They're really nice quality. They fit perfectly within my VST portafilter as the bottom filter, but there's a bit of a gap for the filter on top of the puck, so I've been thinking of looking for a set of 57mm.


I definitely enjoy it, it produces a very sweet, flavorful cup with a better extraction, but at the expense of a thinner body from the filtering. Strangely I seem to get more visual channeling on the bottom of my portafilter, but that might be poor technique on my part.
