I use to have 2. But I gave it away. Its not really safe for airbrush.
So I got me another 2 of this...

With a tip and mid body support or airbrush holder. This is the best one for me.
Why 2? One for Water based and the other for solvent based paints and cleaners.
All this containers can only contain most of the particulate but not the fume.
