I don't concern myself with breathing airborne partials from the mist I just step aside and view the operation from a slight distance up wind if possible providing I have as fan going Heck I've been welding and or smoking for 60 years so a little more crap in my lungs is probably not going to make much difference at this stage in life anyway
The Koolmist did as its name suggests. It created a mist which was messy and not good for breathing. There is another system whose name I forget but it is something like "No-mist" or "Zero-mist" which was the inspiration for my modifications. I did not copy the no-mist system but it gave me the idea. The coolant does not mist, it tends to stay as liquid drops. It works at least as well as the mist but uses less coolant because you are not spraying a sizeable portion around the room. I was so pleased with the modifications to the Koolmist that I made one from scratch for the lathe but I used a smaller filter housing. That was adequate because it is in an easy to fill location whereas the mill one is not so easy.

I just did a search the other system that I mentioned is called "FogBuster".
