Product review (5 stars): Home Depot and Best Buy, I came to the conclusion the "brand' ...
I was skeptical thinking I had to replace the filter with the brand that sold the system.  After searching at the Lowes, Home Depot and Best Buy, I came to the conclusion the "brand' had been discontinued and I would have to place the whole unit or find a replacement filter.  Ordered the Waterdrop Refrigerator Filter and it placed in easy enough.  I waited and no leaks.  Checked it the next day and no leaks.  Worked perfectly and since I got two I won't be ordering for months to come.  But that's OK, because simply...it works!  Price is great compared to other choices, ice and water is clear.  It arrived in two days.
