Product review (5 stars): No difference
I was a bit hesitant after reading some other reviews, but my husband changed the filter and I can't tell that we are using a different brand. The "replace filter' light went off and the water now tastes the same as it did with the Samsung brand. The first few times I had water after changing the filter the water tasted a bit... off, but not bad. I think maybe he just didn't run enough water through it after the installation - for user purposes, run several gallons through before drinking it to avoid the funny taste; he did about 3 and it should probably be at least 5.
