Product review (3 stars): Probabaly not the quality of LG filters.
After the installation, the water was dark (maybe charcoal filter material?) for the first 2 gallons while flushing which is required when installing a new filter. I never saw water black like this when using original LG filters. The other thing I notice is that the water dispenses much faster with this filter. I am concerned because that could mean the filter material is not as good quality as an LG filter.
