Product review (5 stars): Water Filter
A year ago, I redid my entire kitchen and put in water filters where needed. would not work properly unless you replaced the Filter within 7 months.  Anyway, the pressure, etc. seemed to lessen after a 7 month perior.  I hope that I am mistaken, but am checking with Consumer Reports, etc. to see if this is true.  My reverse Osmosis seemed to work great replacing that filter once a year.  If this is true, I would like you to report this to Consumer Report and replace my filter (without charge) each 1  1/2 years  (3 filters) since the seperate one for the LG does not appear to be necssasry and might be called a "rip".
