Product review (5 stars): Best alternative filter I have used yet
I wanted to wait a full filter cycle before I wrote my review.  I found no difference in this brand filter and the original $45 Samsung filters.  I don't run "gallons" of water through my filters immediately following a change, I only run until I no longer see any foreign particles.  With the OEM filters, that is usually about one large Tervis tumbler full of water, and this one was no exception.  (I did run a second cup through it just to be safe.)  In comparison, I have tried 2 other replacement brands and both of those needed at least a full gallon of water before it was clear.  There was no odor, no particles, and no color to the water when using this brand, and it was tight in the refrigerator.  I am very pleased with this particular brand and just ordered 2 more for the next year.
