I was THISCLOSE to buying a Samsung branded water filter from a home improvement store for half of a Benjamin Harrison, then I checked Amazon. Much cheaper and works just as well!

This certainly appears to be an OEM Samsung filter made in Korea. I just changed my filter for the first time and the one that came with the refrigerator was labeled 'fresh water'.  It indicated that it filtered chlorine and particulate Class III, which is NSF/ANSI Standard 42, an aesthetic effect.  The box for my replacement filter was labeled 'fresh water', yet the filter itself was labeled 'mineral water', describing multiple things it filters, which is NSF/ANSI Standard 53, health effects and a much higher standard.

Without knowing more, it would appear the 'mineral water' filter does much more in the way of filtration, but the quality control in packaging is lacking here, as neither is provided or listed as a choice when purchasing and in my case, the box indicated one and the filter itself the other.

That said, so far I am very happy with this purchase.  It fits correctly, no leaks have developed and it appears to be working as it should.  I believe the 'fresh water' filters are intended for city water supplies and the 'mineral water' filters are intended for those who have a well-water supply.  If anybody has more information I would be happy to review it.  Regardless, accurate descriptions should be listed for these different options and appropriate choices should be listed.

My wife is very fiinicky about her drinking water.  Even though we had an under-the-sink water filter, she insisted on buying bottled water because it tasted better.  After we got our new Samsung fridge, she switched to the in-the-door water with no complaints.  Still, the first time it came time to replace the filter, out of an abundance of caution I bought the Samsung approved one.  This time, though, I chose the Water Sentinel.  Princess approves!  No more bottled water!  I'm going to buy the 2-pack next time.

Tried a Samsung water filter on my Samsung RF268ABWP Refrigerator but due to a design change would not fit. Purchased the WaterDrop 3-pack, and they fit great!

I purchased only one filter so I could test it out for myself.  I am happy with my purchase.  The filter was packaged well.  It fits my refrigerator perfectly, and the water takes great.  The price is reasonable, especially compared to the Samsung brand filters.  I recommend these filters, and I plan to purchase more.

I have the samsung 2 drawer model.  At first when I put the filter in the fridge, it made a weird grinding sound. I checked some online forums and concluded that it could be debris. I remove the filter and clean the area well. Then I reinserted the filter and it works brilliantly. No issues at all. Water taste great.

These water filters worked seamlessly with my SAMSUNG French door refrigerator.  No problems whatsoever.  No leaks.  I had them installed in about 10 seconds.  Highly recommend.  Don't waste your money on the SAMSUNG brand filters, they are ridiculously priced.

This filter worked for two weeks and then the water and ice started to have a terrible flavor and smell. I will stick with factory Samsung from now on.

So not sure about the previous reviews stating that these cost more in a 3 pack versus individually, when I did my shopping the 3 pack was less expensive (not by much, but still).  This filter went into our Samsung fridge (these are OEM Samsung filters by the way, not 3rd party) RF4287HABP with no issues, just like the filter that came with the fridge.  Water tastes fine, no issues there - I don't have a way to measure the crap in the water, so I can only assume the filter is doing its job.

I had the fairly common Samsung refrigerator issue of water not dispensing when the filter was in place. I could take it out, run some water, then put it back in and it would work for a short period before hammering to a stop again. This is the faulty part to fix it and it has worked perfectly since. I only used Samsung filters before the problem happened, so that's not a contributing factor contrary to what others may say.

I used this on a Samsung model RF28HDED/TSR.

I've attached annotated pictures of the install process. I could not find video or details online of this (besides taking off the glass shelf), so hopefully this will be helpful to others.

This comes with the white tube attached. I just took that out and used the only already installed. Running the tube through the refrigerator would make things more difficult and that's not the problem here.

This filter is slightly smaller in diameter than the OEM product.  I had no trouble installing it and have not experienced any leaking at the connection. Water flow, filtration, and lifetime capacity (gallons) is equal to the OEM product.  A very good value when compared to the pricey Samsung OEM filter.

Did not function properly in my Samsung refrigerator.  Once installed, refrigerator water dispenser made the typical rattling it would do when the filter is clogged from use.  After purchasing a Samsung branded filter, and inserting it instead of this filter, back to normal.  Not shocked, since this filter is $8 and the Samsung filter is $50.

For many years I have bought this model replacement filter in both Samsung brand and knock off brands.  I've never had an issue with fit or function.  Until now.  As other reviewers have noted, Samsung has changed the size/spacing of the plastic tabs on the filter locking mechanism for this model filter and it will no longer fit in my refrigerator.  Samsung insists the two designs are compatible and that we just need to apply more force.  No...it will not turn...at all.  No matter how much pressure my husband applies.  The grooves are different and it just doesn't fit.  At first I thought it was an issue with this brand....ordered the expensive certified Samsung model instead and same issue.

Edit:  Another reviewer suggested a fix to this problem that worked for us.  You can use an exacto knife to trim the plastic tab on the bottom right side.  After making this adjustment, we were able to install the product.

I had been getting the replacement filters at the appliance store every time the "warning" light went on.
The Amazon price was better, delivery was quick, and I ordered the 2-pack.  It's the only way I'll ever buy these!!

Update:  Since installing there has been a major leak.  Apparently this is a current issue with Samsung.  This is a different filter than the earlier ones -- I thought it was meant to be improvement.  Wrong!!

My preference is to use a filter made by or recommended by Samsung for their refrigerator, knowing that it's more likely to fit properly and perform as expected.  There are many generics out there that are probably less expensive, but I would rather not take a chance that could result in a water leak and related damage.  It seems to work as intended and we use the water and ice from the refrigerator for drinking and cooking because of this filter and what it's supposed to be doing.

I like the fact that this product is so much cheaper than the brand-name. Everything was great including  delivery. One thing that Im not 100% thrilled with is the fact that the water flow seems to be a little restricted with this filter as opposed to the Samsung brand so the water doesnt come out the strong and as quickly. Other than that everything was great
