Frankly, I agonized over using an OEM replacement for my GE MWF; I figured there had to be a difference.  What was shipped looked exactly the same as what I took out of my refrigerator; I installed the filter, noted the date on it with a Sharpie, ran a couple of pots of water through the spigot until the residual charcoal was flushed and the air-pocket sound was gone - and that was that.  No leaks, no problems, no vapor locks.  I didn't get a discount for writing the review - I'm just a guy who bought a filter online.  Kudos to the folks at Pure Line, and to the reseller for prompt shipment.  I'll be doing this again!
