We have argued this in the past and I seem to recall Dale that you admitted to having zero personal experience with funnel systems. For the record, Mine worked very well and moved a huge amount of air. The downside as I stated is that you must work directly in front of or directly below the funnel for them to be effective but thats no surprise. By the way, mine was not a filtration system but was designed to exhaust through ducting. Again, for your application I think you need an overhead hood.
