Yeah, skip the filtering all together. If you let a concentrated solution sit long enough at (or less than) -20 degrees, crystals should be forming at the sides of the container. This should allow you to carefully pour the naphtha into another container (for reuse in another pull) while turning the jar, and then quickly put the lid on and let it warm to room temperature upside down. The little amount of floaters will redissolve and reappear in next pull anyway, so there's nothing to loose (compared to the filtermethod).
There's a clear difference between what I say I do and what I actually do perform.
