Review on 🌪️ Oneida Air Systems Super Dust Deputy Deluxe — 4-Inch by Joe Calabro

This thing really does collect 99.9% of dust before it gets into your filter. but not crazy about the box for the collection. Also, the bottom of the cyclone just comes up to the edge of the collection bin, the supplied foam tape needs to be fitted hanging slightly off the bottom of the cyclone to allow the foam to fill the gaps. left too small diameter of the built-in cyclone cover. still an easy way to build a large cyclone. I have a 90 degree turn at the entrance to the cyclone and it still separates very well.
