Removing CFC Dust From the Air

My wife is not happy at the CFC dust that milling and turning CFC puts into the air. (I wear a respirator.)  This stuff goes everywhere, leaving a fine coat on everything.  She wants me to stop machining it for that reason.  If I had a completely separate shop instead of the garage, this would less of an issue.  (Next house will either have a separate building or i will have one built.)

I suspect that someone sort of ionic air filter would pull this stuff out of the air and either leave on an anode or drop it in a neat little pile.  Shops that work will this stuff must have a fix.

UPDATE: I asked Grok. It suggested the Jostart KL306 which uses carbon fiber tips to produce ions to clump carbon fiber dust together immediately around the tool. These came in a 3 pack. I will try one at the mill to see if it works well.  If it does, one for the lathe, drill press, and sander.

UPDATE: My wife read the hazard description for CFC and it is now permanently banned.  I will sell the remaining pieces on eBay.

    Haven't done what you are doing, but some exotic woods produce toxic dust from woodworking tools. Even if you get a separate workshop you might want to look into dust collectors (though aluminum in dust collectors can lead to fires, because aluminum dust can be an issue.)
