Product review (3 stars): Not sure if the filter material is same as LG version
This filter is much cheaper than the LG equivalent and seems to work well. Like others have mentioned, you initially get black water from the charcoal dust, but this soon disappears. My one concern is that within a week of installation water started appearing under the fridge. I ended up having to have a new relay which controls the water flow installed at over $300. I do not know if this was a result of some sort of back-pressure from the filter, or just a coincidence. I mention it for your consideration!
