Product review (4 stars): Excellent product and price
Fits LG just like the factory filters and reduced total PPM very efficiently.  I use a five filter RO system to get street water down to about 11 PPM and this internal filter reduced it to 5 PPM for the ice maker and chilled door water use.  That's clean and at less than half the price of other filters.  Shipping was fast and well packaged.
