I know it is a brain melter, but look up Bill Pentz' dust collection research.

Generally speaking, the tiny diameter / small motor dust collectors aren’t going to do a tinkers hoot.

Your best low $$ option is to…

#1. Buy a used Harbor Freight 2HP Dust collector. Or a new one if you catch a sale / coupon. Don’t pay more than $100.00 for a used one. #2. Build an internal Thien Baffle for your Harbor Freight Dust Collector. #3. Select the Wynn 35A canister filter of your liking, form the least expensive (paper filter) to the most (nano filber). I went with the spun bond poly because it is washable.

The size of your ducting matters, a LOT. The HF DC will support 5” duct, if you can run 5” to the tool and neck down if you have to and get to a 4” port, do it. The idea is to have as much air flowing inside the system as possible. If you roll the DC from machine to machine, keep your hose SHORT.
