I used to have a rainbow vacuum cleaner. best vac i ever had in my life and served so many other purposes than just a house vac. But what i am wondering how it would be to make a dust collector on the same principle. Or at least try and get the big stuff out and have a water container get the 2 or 3 micron sized dust.
I have had others argue but I have alwasy been told that water is the best filter possible.
Any thought? or has anyone done this?
