This gentleman seems to be having some success with a simple, inexpensive pvc filter system. He has more current videos, of a much more refined Imbert Downdraft Gasifier on his youtube channel.

I’ll be following your journey.
Lastly, I couldn’t help but think that his filtration system was ultimately a filter and radiator system to not only clean the gas but to cool the gas at the same time. Cheers to you sir!
