agreed, but if the decicate bag fills up with outside mositure, you have no way to catch any more of it that may get into your system, we have to replace it anytime we crack the system at my shop, i would rather be safe than sorry, a $20 dryer is alot better than a $600+ ac compressor, but i do understand your point
