Thread: Dust Collectors - Wood

Can anyone recommend a dust collector in a smallish workshop for mainly filtering out wood dust generated mainly by sanding knife scales?
I am using atm dust face masks but there is too much dust accumulating and the vacuum cleaner attached to the sander is not doing it well.
Any recommendations on what works and what to avoid when buying new or used?
Any pictures of your dust collectors and how they function would be much appreciated.
The sanders I use are all home made and have no dust port attachments.
Cheers
