Cyclone Dust Collectors: Gorilla vs. Clear Vue vs. Grizzly

For those new to wood shop dust collection, a cyclone dust collection system differs from older dust collection systems because almost no dust reaches the filter - it all ends up in the collection bin. Until I started reading through this thread on WoodNet - with over 200 posts - I didn’t realize that nothing stirs the woodworking hornets nest like CYCLONE DUST COLLECTION. The extreme polarities in WoodNet seem to come from - as far as I can tell - these points:

1) Lack of objective comparisons - most woodworkers have only had experience with one cyclone dust collection system
2) Bias towards Clear Vue inspiration and woodworker Bill Penz who has an almost cult-like following
3) Lack of understanding of the science of dust collection and dust collection systems

I went through the WoodNet thread and added in one from SMC for good measure. I counted how many had bought which systems, but this doesn’t give you too much to go on… Following my tally are some sources that I hope can help you get up to speed on your cyclone dust collection decision… or make your own.
