I can't recommend any good filters, though I'm going to be trying these in my closed loop soon (once I actually run my closed loop. could be a week or two). http://www.amazon.com/Ahlstrom-0540-0700-Quantitative-Filter-Diameter/dp/B006H8QRJC/ref=sr_1_6?ie=UTF8&qid=1408804334&sr=8-6&keywords=10+micron+paper+filter. They also have glass roving filters that go down to 3 micron, which I might put after the 10 micron, but those filters cost like 80-120$ for a pack.

I think can tapping will definitely help. I had no issue using 25 micron while blasting open. To be honest, I think even 15 micron would still flow nicely. tbh, I'm just guessing.

If you haven't already, these guys have some pretty fine mesh was considering getting the smallest. Steel would be stronger than filter papers, I'd imagine.

Yep! You already have the vacuum pump, all you need is the buchner funnel, filter paper, and syringe filters. The only other real cost is the everclear, terpenes, and cartridges.

Your first pass through the funnel will be just with coffee filters. 2nd time use the 10 micron that comes with the funnel, 3rd time use the 2.5 micron, and finish up with the syringe filters. Its the only way I've been able to make a cart wick and not taste burnt. I just use the fruit frenzy shatter batter for flavor, it comes out a little runny but works well. They have other flavors as well. The grape is like a grape ice pop. I would avoid unless you like those lol. Theres some videos on the shatter batter page that shows how to do it. Don't do the microwave thing, do the double boiler.
