Product review (5 stars): Good Replacement For GE GXRTQR Ice Maker Filter
First off, this is indeed a replacement for GE GXRTQR filter. It does _not_ include the installation kit (that splices the water line, etc...&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/LDR-509-5100-Ice-Maker-Humidifier-Installation-Kit-1-4-Inch-x-25-Foot-Poly-Tubing/dp/B000I1ARN6/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">LDR 509 5100 Ice Maker/Humidifier Installation Kit, 1/4-Inch x 25-Foot, Poly Tubing</a>). It's pretty non descript, but thankfully, does indicate which way the water should flow.

Now then, yes... of course, when you first connect this to a line, it's going to discharge some of the charcoal inside (ie. grey water). They all do this. So what you do, is connect one end, and let it run water into a bucket for a while. I also suggest stopping the water flow with your finger a few times and REALLY get the excess out. Otherwise, your first few ice cubes will be grey.

With that in mind, assuming this thing lasts for a while, this is a great replacement.
