Product review (5 stars): these filters are hands down the best. Unlike the other brands that I tried
After purchasing a Samsung refrigerator two and a half years ago, I've consistently purchased these replacement filters about every 6 months. I was hesitant to purchase these initially, as I wasn't sure of the quality of the filtration and the fit for my refrigerator. After trying two other filter brands (both generic filters purchased online), these filters are hands down the best. Unlike the other brands that I tried, the water from these tastes great and I haven't noticed any decrease in water flow from the factory included filter. These also were noticeably heavier than the generic brands, which I'm guessing means more filtration in the filter.

A few notes:
1. Prices on these can fluctuate.  As of this review they're $6 cheaper than they were in April, the last time I purchased. If you see them at a reasonable price, stock up on a few to save money down the line.
2. Always check the prices for the single, double and triple packs.  Ordering multiple singles can be cheaper than the double or triple packs.
