Yes and no.
Medical grade is the same as automotive use stuff as far as performance, there is no difference.
Nitrous sold for performance is supposed to have 200 PPM sulfer dioxide in it....to revent people from huffing it and getting high....the sulfur dioxide prevents those folks from even one instant attempt to huff it, it is nasty smelling stuff.
Filter between mother bottle or filling pump and smaller bottles to keep those clean, and some use a small sintered brass filter in the nitrous soleniod inlet fitting...some don't due to not wanting any chance of flow restriction.
