Product review (5 stars): LG Filter works fine.
I purchased the "A" version of this filter because we are on public water supply of good quality. We don't really need the extensive filtering and treatment others might need if on well water. The "B" version is more expensive and provides a bit more chemicals removal. I focus more on taste and both versions of this filter seem to have some slight plastic taste. The B version is more expensive and in my opinion is not worth the small incremental improvement in chemical removal. Both filters have the same flowrate and fit the LG and LG made kenmore refrigerators. Filter Unit is very easy to change, fits perfect every time and has not had any leak problem ever. Just wish these did not cost so much! Great price and shipping on Amazon.
