Product review (1 stars): Do Not Buy! Rip Off Imitation
I am extremely disappointed with this product. It is a cheap imitation of the authentic filter. Lesson learned for me! I bought this because it is  a cheaper replacement for my 18 months old LG filter. It installed just fine and fitted perfectly. However, the water quality is extremely poor even after 4 gallons of water flushing through this new filter. My tap water has 465 ppm of TDP. My 18 months old LG filter has 97 ppm. This "new" filter was able to get the water down only to 420 ppm. Acceptable drinking water is 300 ppm. The bottom line: do not waste your money or risking your health buying this product.
