I have a V-3000 system that has been great for dust collection in my hobby woodshop. Put it in a "sound proof" closet which of course creates the problem of being out of sight and thereby forgetting to empty the bin on-time sometimes. It really is a pain to clean the filter!!! The system is 6+ years old and I am contemplating replacing and up grading the filter. Oneida's new nano filter comes thru at $340 and what appears to be closely equivalent the Wynn filter costs $205. Does anyone have any experience with these two filters to justify the price difference? Clean-ability and longevity are important to me. Wynn claims significantly greater surface area, but i remember a recent test in one of the WW magazines and the Oneida filter was the winner hands down. $135 is a lot of difference is it really worth it?
