One of the forums discussing dust collection, was suggesting that the air scrubber type dust filter spreads around the dust that it can’t catch.
I certainly can’t argue with that but it does sound like a bad design and lack of understanding of what needs to happen.
There are many circumstances, in an active shop where it’s virtually impossible to catch all the dust at the source and that’s something that this fellow fails to grasp.

Anyway, he went to explain that whatever he had bought for a dust scrubber was sucking dust out of the air from the front of the machine and apparently blowing it right back out the back.
If that is the case with the scrubber you’re currently using, I would suggest you analyze the filters in the unit and try to come up with a pre-filter with a fine enough mesh to trap the dust before it makes circuit around your shop.

As Lee Jesberger pointed out earlier, by actually disturbing the dust that has settled in the wood shop, and getting it airborne again allows the scrubber an opportunity to remove it from the ambient air. As most of you realize having spent some hours in your own shop the fine dust has an amazing way of finding itself into every nook and cranny of your operation.

By mobilizing these fines and putting your dust collector(scrubber) on a timer, you can scrub most of the area clean in the period of a few hours use and when you’re not in there too!

It’s not perfect but running without one is a poor subsitiute for good shop hygeine.

I did not mention helmets but they can provide some protection but at the expense of your comfort and are bulky to wear and hevey on your neck muscle after a few hours.
