Product review (4 stars): Bad Batch of WSG-1 Filters? Turns out NO!
I have used the Water Sentinel WSG-1 in my GE refrigerator for years with excellent results. We have well water, high iron, and sediment. Our $10K water treatment system doesn't quite do the job, and we have to filter water for drinking. Up to this last order, the WSG-1's worked perfectly, producing sparkling clear, good tasting water. With our sediment load, we have to replace the filter every 2 months, instead of the recommended 6 months, so having a lower cost alternative like the WSG-1 was good.

However, the most recent filters did not adequately filter, or not filter at all. Tried 3 of them from the order of 6, all produced colored water, and it appeared that the water was either by-passing the filter, or just not being filtered...(defective filtration material)? The water also came through the filters faster and in larger quantity than past WSG-1's, faster than it should being forced through filter material.

Anyone else experienced this problem with WSG-1's?. The only alternative seems to be the GE MWF at twice the price.

EDIT: 9-17-2013...turns out that it was the refrigerator at fault. The very large threads that these filters screw onto had worn to the point that the lever that redirects the water flow through the filter was not being depressed. So, I will revise my rating to the previous 4 stars i have given this product.
