I don’t know if anyone else used one of these, but they’re probably the best airbrush cleaning station on the market, if you can still find one off of the Olympos Airbrush online site. They’re built super sturdy. When ready to clean them, disassemble and just throw it in the dishwasher. I use a cotton ball in place of the factory filter as well.
Never needed one, my spray booth sucks ups harder than a politician wanting a vote, and it vents outside so there is no bad breath like a poly, from all that ass kissing. Sorry we just voted in the next lot of thieves in OZ recently......
