Has anyone tried using a water filled container as a filter for dust
collector exhaust air? Sort of like a bong in reverse - the dirty air
gets exhaused under water and bubbles up to the top, where the water
will filter out all the sub-micron dust?

I'm just looking for a cheapskate alternative to 0.5 micron filter
bags.

Any suggestions, comments or other ideas?

The Borg and other places sell exactly that for sanding drywall. It
should work for fine wood dust.




Probably a real bitch to clean, however.
