Perfect Fit for Multiple Samsung Fridges and Great Value
I have two Bespoke Samsung fridges that both needed filter cartridge replacements, and these worked perfectly for both. The fit was exact, and installation was quick and hassle free. The water quality has been great since switching to these. Everything tastes clean and fresh, just like with the original filters, but at a much better value. I also like that this comes in a 6 pack since I have two refrigerators. It makes it easy to stay on top of regular replacements without having to reorder all the time. Overall, these are a reliable and cost effective alternative to the original filters. If you have multiple Samsung fridges or just want to stock up, this is definitely a great option.

Excellent and Affordable Alternative to OEM Filters
An Excellent and Affordable Alternative to OEM Filters The waterspecialist DA97-17376B Replacement filter is a fantastic choice for anyone with a compatible Samsung refrigerator. This replacement filter offers exceptional performance and provides great value compared to the more expensive original equipment manufacturer (OEM) filters. Installation was a breeze, with the twist-in design sealing and fitting perfectly into my Samsung refrigerator without any leaks or issues, just like the original making it fully compatible with the OEM model. My family has noticed a significant improvement in the taste and clarity of our water and ice and experienced no significant change in water flow. It effectively reduces a wide range of contaminants, including chlorine, odors, and other impurities, all verified by third-party testing. The filter is also certified to NSF/ANSI 42 and 372 standards, giving me confidence in its quality and safety. Plus, waterspecialist includes monthly install stickers, which are a helpful reminder to replace the filter every six months for optimal performance. For a reliable, high-quality, and budget-friendly water filter, the waterspecialist DA97-17376B is a top-notch option.

Important tip for Samsung side by side fridge is to shut off water to fridge first!
We have a Samsung side by side refrigerator and these have worked perfectly! One important tip for this kind of refrigerator is you must shut off the water to the fridge before removing the filter to replace it. If you don’t then as soon as you start to twist the filter to remove then a lot of water comes spraying out and you have a mess to clean up! It’s really simple to turn off the water, unscrew the old filter and screw the new one back in. (Twist clockwise to install and counterclockwise to remove.) We’ve not had any problems with it leaking so the size is perfect. The package does say to flush about 2 and a half gallons of water out before consuming any of it to clear the carbon out. It is well made and durable. I find it very easy to use and water tastes fresh. Occasionally it is hard to unscrew the old filter out so I just use a pair of pliers. It’s such a great price. I never hear any kind of noise come from it. We’ve used this brand for almost 2 years and have had no issues so we recommend!

Great Value and Fixed the Water Dispenser
I was visiting my grandma and noticed the water dispenser on her Samsung fridge was barely working. After looking it up, I saw that changing the filter could help. I found these on Amazon, got three for about the price of one Samsung filter, and they arrived overnight. I installed one, and the dispenser started working again right away. Great value, easy to install, and they work well. Highly recommend and would buy again.

Perfect fit they do the trick!!
This is the second time I purchased these. They're a really good deal, they fit my water filter area perfectly. They're easy to install. My water taste so much better when these are installed, I can tell when they need changing even before my calendar, reminds me to change them.

These are a perfect fit, no leaks, and the water tastes identical.
For years, I stubbornly bought the official, name-brand Samsung replacement filters for my refrigerator, spending upwards of $45 to $50 every six months for a single filter. I was hesitant to try aftermarket brands because I was terrified of water leaks or poor-tasting water. I finally decided to give this Waterspecialist 3-pack a try, and I am genuinely kicking myself for not switching sooner. At under $30 for a pack of three, this is an absolute no-brainer. Here is my detailed breakdown after installing and using them: The Good: Perfect, Leak-Free Fit: This was my biggest concern. I am happy to report that these lock into place exactly like the OEM Samsung filters. The engineering is precise. It clicked right in with a quick twist, and I have experienced absolutely zero dripping or leaking inside my fridge housing. Crystal Clear, Great Tasting Water: The water quality is indistinguishable from the expensive name-brand filters. The coconut shell carbon block does a fantastic job of removing that heavy, chlorinated city-water taste. The water comes out crisp, clean, and completely odorless. The ice cubes also taste perfectly fresh. NSF Certifications: It gives me a lot of peace of mind knowing these actually hold independent NSF 42 and 372 certifications for lead-free material and impurity reduction, rather than just making empty marketing claims. Thoughtful Extras: They include a sheet of month stickers in the box. You just peel off the current month and stick it right to the front of the filter so you don't have to guess when your 6 months are up. It’s a small touch, but incredibly helpful. Important Things to Keep in Mind (Before you buy!): Check Your Filter Shape! As the manufacturer notes, these are the SQUARE filters (HAF-QIN style). Do not buy these if your current Samsung filter is perfectly round and cylindrical (HAF-CIN style). Pull your old filter out and check the shape before adding this to your cart! Remember to Flush It: Just like the expensive name-brand filters, these are carbon-based. When you first install it, you must run about 2 to 3 gallons of water through the dispenser to clear out the loose carbon dust and trapped air. The first few cups might sputter or look a little cloudy - this is totally normal. Just keep dispensing until it runs clear. The Verdict: If you have a compatible Samsung refrigerator, stop overpaying for the OEM logo. The Waterspecialist filters offer the exact same fit, the exact same water quality, and the exact same lifespan for a fraction of the cost. A single purchase of this 3-pack will cover you for a year and a half. Highly, highly recommended!

Great product
These are a great, budget-friendly alternative to the name-brand filters and perform really well. They can be a bit tricky to install at first, but once in place, they work perfectly. I’d definitely buy them again.

Good Budget Replacement for Samsung Filter
The Waterspecialist DA97-17376B replacement filter for Samsung refrigerators works well overall. It fits properly, is easy to install, and provides good water taste and odor improvement. The price is much more affordable compared to the original Samsung filters, especially when buying a multi-pack. It is also NSF certified, which adds some confidence in its filtration performance. However, it is not an official Samsung OEM part, so long-term durability and filtration consistency may not be exactly the same as the original. Some users prefer OEM filters for peace of mind. Overall, it is a good budget-friendly alternative if you want decent performance at a lower cost
