@IRON HORSE posted:Attached is an older video clip of my Airpura air purifier running with my MTH engine at full smoke. The Airpura unit was recommended from a fellow forum member. It's a little hard to see. The smoke rises toward the ceiling but then shifts downward toward the black air purifier on the floor. Once it travels to it, it disappears. And within a few hours after running trains the smell of smoke is completely gone. It also reduces dust and works great when you're painting or use foam burning tools or soldering.
As I stated earlier, I like it because you can physically see where the smoke is and disappearing, allowing you to stay away when you don't want to breathe it.
Great demo Russell.
My layout is in what is referred to as the Florida Room ( I'm in central Pa. 
) . The layout is almost surrounded by 48 linear feet of windows with solid draw string window blinds that are only very slightly drawn opening .
I seldom run smoke on my MTH steamers but after a year or so , there is some" fogging " on the window glass which I assume comes from the smoke oil. I only use MTH or Lionel smoke fluid .
Thanks for the info on the Airpura Russell . 
I'll have to look this item up.
