A/C Filters inline?
 

Someone recommended that I install inline AC filters while replacing my compressor and recharging system.

What do you guys think about that?

I've heard that too. This is because compressor failure can sometimes send particle debris throughout the system. Even after flushing to remove the debris (I hope you're including a flush in your repair schedule), there may still be some debris in the system which can kill the new compressor. One exception to this is if you're replacing the compressor because of shaft seal failure or leak and nothing else is wrong with the compressor. The filter would ideally be installed just before the compressor on the low (suction) side.

The reciever/drier is a filter...

It's more like a piece of screen door -


Doesn't do anything for small metal debri.


You can buy filters with beadlock fittings on the end.


Bascily you find a part of the low pressure rubber hose where you want to put it - cut a section out and have a hydraulic or AC shop crimp the beadlock filter inline.
