there are 3 types of dust control
!. A whole room air "filter" that hangs above and filters the room air, probably a good idea regardless of what other types you use.
2. A shop vac connected to the dust port on the tool, routers have an accessory gizmo from Rockler that catches the dust off the bottom. Sanders like Dewalt have a dust port for a little bag filter, basically worthless, but better than none. A shop vac with a reducer hose will work 100X better.
3. A standing floor unit Dust collector,
Table saws requires 2 types, but generally only has one large opening either on the bottom or at the rear in the case on a contractor type saw. The newer job site saws have a 2" ported blade enclosure that works pretty well. The 4" Dust collector standard hose is used for the bottom or rear ports. I prefer a blade collector as well which mounts on the top of the saw and collects the dust off the top of the blade and also acts as a guard. You can make one from 2" PVC and mount it in several ways. ...on the floor hang it over head, on the top of the saw, on the splitter if you have one. There are commercial ones fro $175.00 to $400.00 or so. ...not necessary if you are creative and "cheap" :laughing:
So, to really do the job you'll need and overhead filter, a shop vac, and a Dust collector like suggested a Harbor Freight unit with a 2.5 micron bag or 1 micron filter cannister.
Cheapest is the shop vac. Then the Dust collector, then you can make a room air filter from a box fan and some furnace filters...you just can't move it around much because the dust will fall off and back into the room. I know this from experience. :thumbdown:
When I had a basement shop I would put a box fan in one window and push out the air from an opened window across the room. It will also remove all your heated air in the winter, but it's better to be cold than breathing in the dust. The return air ducts in the basement must be sealed to prevent fine dust from being redistributed by your furnace to all the rest of the house.... wifey will appreciate that.:thumbsup:
