no matter what method you use you will always have some saw dust on everything around the area.
even pro shops that use very expensive dust collection systems have dust come out of their saws.
the problem is the blade! the blade is open to the air, therefore so is the dust coming from it. all you can do is minimize the dust at most!

i have a small home shop and i use an attic fan to pull air out of the shop and out the window. as long as my door to the shop is closed this creates a negative pressure inside the shop. this way the dust stays in the shop and not the rest of the house. i also aways use a shop vac attached to the table saw.
