Well, the orifice tube has a fine mesh screen built in & the
receiver-dryer is there to remove any moisture. A/C suppliers do sell
filters that could be spliced into your system I suppose. Why do
you think you need one??
I just didn't know if one existed in this system. When I bought the car the AC
didn't work. So I replaced all the O rings and the shaft seal on the
compressor, then pressure tested, . If a filter existed I would have replaced
that too for good measure. AC is up and running cold now.
