Product review (4 stars): A bit Pricey but Works Well
These filters are a bit pricey at over $30 a pop, although that is on par with other brands.  Amazon is definitely the place to buy these though, as stores tend to charge $40+.  Depending on how much ice and water you use from your fridge, you will have to replace them at least every 6 months.  We use ice at the rate of a few glasses a day, but rarely use the water from the fridge as we have a separate water filter at the sink.  After about 5 months, I could tell the ice was getting that "funny taste".  I ordered one of these filters, changed it and back to the great tasting ice we were.

I have the Samsung RF4287HARS fridge and this is the correct model filter for it.  Changing it is incredibly easy:  just shut the water off, twist out the old filter and twist in the new one, then run a gallon or so of water to clear the filter of carbon dust and to remove air from the lines.  I believe you can install this without turning the water off, but I'm paranoid of that so I shut it off.

As a note, when ordering one of these keep an eye on the price of this versus the 3-pack:&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Samsung-DA29-00020B-Refrigerator-Water-Filter-3-Pack/dp/B004UB1O9Q/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Samsung DA29-00020B Refrigerator Water Filter, 3-Pack</a>.  Depending when you hit it, there may be significant savings in the 3-pack or it may be cheaper to order the single.  The price seems to fluctuate daily. In my case, it would've cost an extra $2 for each filter to order the 3-pack, so I went with the single.  It looks though that the 2-pack is always more expensive, so avoid that.

Overall these are very convenient to install and work well.  Spending almost $70 a year just to filter water for a fridge though is a bit extreme, so I give it 4 stars.
