I know that I will not change some minds and sorry if I upset anyone. No, there is no way one can collect all the dust but you can do whatever is reasonable. Do some websites go overboard…yes BUT
The effects of wood dust on health is well documented. I use a dust collector and air filtration and a HEPA vac on my sander. I do not have any breathing problems and do not want to have any. If you choose to think it is not important for health…that is your opinion.
