    What's the difference between a bi-flow and a uni-directional? Would a uni-directional prevent flow in the opposite direction?

    What?

    I replaced it with the correct bi flow filter drier when I replaced the compressor today. I can't believe it took a few years to kill the compressor.

    Yes it would.

    Lol. It might help to have a bi flow. I went to a call after a fellow tech installed a straight cool filter/dryer backwards. I showed it to him. and he blew through it backwards and said "whats the difference"? I said blow through it at 250 psi

    The 250 psi is relative to atmospheric pressure. The differential pressure across the drier is almost zero. So the amount of resistance to flow should be no different than blowing through it with your mouth.
    I think the difference is in the configuration of the screens and desiccants.

    did anything fall out of the drier when you removed it (hopefully you cut it out instead of unsweating it)?

    I did cut it out, and no, nothing came out.

    Maybe he thought your supposed to replace it every spring and fall.

    Got a walk-in freezer out there that's been running for at least 10 years with the dryer piped in backwards. I think it just doesn't filter properly being installed in the wrong direction and has no affect on flow!

    but this was a heat pump, so the use of a one way filter is like having no filter at all.

    Still not a 100% on if it killed the compressor.
