Results (edited post with new info):
Filtering with lab filter paper leads to essentially no residual powder in the oil, but takes a very long time, even using the higher micron paper. Also, the low alkanet root : oil ratio was not sufficiently dark to my eye, especially compared to the higher concentration long-brew.
Here is the new oil and the slow brew high test oil filtering side by side.

I decided to add another 1/2 tsp to the new red oil, warm it in the microwave, and leave for 24 hours. I filtered it again with the high flow paper, but warmed it again before filtering to decrease viscosity. This helped.
The result was an oil that is just as dark as the long-brew oil, and with essentially no residue in it.

I also had a little real turpentine with alkanet steeping and I decided to filter that through the paper as well. The color is very dark and the filtration was much easier.
