Product review (4 stars): would be better if they would lower the price
Stick with brand name Samsung water filters.  I'll admit- I was wrong.  I tried the off brand.  They save very little money, but don't last as long, filter less and you don't have issues you have with the off brand.  I've also read where they leak, although I never had any filter leak either  Samsung or another brand. I'd give 5 stars if they weren't so expensive, i'm not sure if they're worth the price. It seems like they might just be taken in vantage of the fact you have to replace them after a while. But I will say, our water is terrible any filters do clean the water very well, so it's possible they are worth the money.
