Product review (1 stars): Doesn't improve the water quality according to measurement, no improvement in taste either
I purchased the SGF-LB60 for Kenmore refrigerator to replace the original part 469990, 5231JA2005A.

The SGF-LB60 is equivalent of 5231JA2005B, difference being the last letter B. The B series filter is suppose to filter more contaminants compared to the A, the description and the cartridge lists 13 different contaminants. Whereas the A only lists 2.

I used the http://www.amazon.com/gp/product/B002C0A7ZY/ref=wms_ohs_product?ie=UTF8&psc=1#productDetails device to test the water quality.

Ideal drinking water should read between 0-50.

- Tested the water at faucet unfiltered, reading 193
- Original Kenmore 5231JA2005A, reading 147
- Tested the water from the fridge after replacing with LB60 filter, reading of 196 (slightly higher then unfiltered, surprise?)
- Tested a Poland Springs bottle water, reading 36

Mind you the original Kenmore filter was past due by over 3 months.

Now, granted I am not using state of the art scientific equipment, nor am I a chemical engineer. But the simple logic that my readings were better with the used 9 month old filter then they are with the new filter, which one would expect to produce better results.

Very disappointed.
