A Samsung refrigerator water filter comes in three shapes, and the three look nothing alike. The newest is a slim bar almost nine inches long. The oldest is a short round can about the size of a coffee mug. Between them sits a cartridge that releases with a quarter turn inside the fresh food compartment.
That is the whole routing problem in this category, and it settles in one look. A shopper who holds the spent cartridge up and reads its shape has the answer before any model number gets typed. A shopper who starts from the appliance model number has to work through Samsung's part codes, and those codes changed twice.
This guide sorts every Samsung cartridge Poseidon Filters stocks by what it looks like. Each section quotes the dimensions, the rated life and the certification line from the product listing itself.
The three shapes, side by side
Every figure below comes from the listing named in its row. The Samsung refrigerator water filters collection carries the current stock.
| What the spent cartridge looks like | Samsung code | Cartridge in stock | Price |
|---|---|---|---|
| Slim bar, 2.13 by 2.13 by 8.86 inches | HAF-QIN, DA97-17376B | Replacement Sam-sung DA97-17376B Refrigerator Water Filter HAF-QIN HAFQIN/EXP | $28.99 |
| Interior cartridge, quarter turn to release | HAF-CIN, DA29-00020B, DA29-00020A | Sam-sung DA29-00020B Refrigerator Water Filter, or the compatible Gold Series GS-S2 Refrigerator Replacement Filter Fits Samsung HAF-CINS/ DA29-00020B | $37.99 or $19.99 |
| Short round can, 5 1/2 by 3 1/4 inches | HAFCU1, DA29-00003G | Gold Series GS-S1 Refrigerator Replacement Filter Fits Samsung HAFCU1S/ DA29-00003G | $19.99 |
Four cartridges cover the whole Samsung line, and the shape of the spent one picks the row. The rest of this guide is the detail behind each.
The slim bar: HAF-QIN and DA97-17376B
Samsung's newest cartridge is a square-section bar. The Replacement Sam-sung DA97-17376B Refrigerator Water Filter HAF-QIN HAFQIN/EXP listing publishes it at 2.13 by 2.13 by 8.86 inches. Nothing else in the Samsung line has that profile, and nothing else in the line is that long.
The listing names side-by-side and French-door refrigerators as the cabinets this cartridge serves. It puts rated life at 6 months or 300 gallons, whichever comes first, and flow rate at 0.4 gallons per minute. Operating pressure runs 30 to 125 psi and the country of origin is Korea.
Certification on this cartridge is the most detailed in the Samsung line. The listing states that the DA97-17376B meets American National Standard NSF/ANSI 401 testing for emerging contaminants in drinking water. It adds that the HAF-QIN cartridge is tested and certified by NSF International to meet or exceed NSF/ANSI Standards 42 and 53.
NSF/ANSI 401 is the standard worth understanding before choosing between cartridges. It covers what the industry calls emerging contaminants: trace pharmaceuticals, pesticides and chemicals that municipal treatment was never designed to remove. Standard 42 covers taste and odor. Standard 53 covers health effects such as lead and cysts. A cartridge certified against all three has been tested across every layer a household drinks through.
The price sits at $28.99, and it is the lowest price on a genuine Samsung-branded cartridge in this catalogue. That combination puts the widest certification in the Samsung line at the lowest genuine price in it.
The interior twist: DA29-00020B and HAF-CIN
The second family lives inside the fresh food compartment. The Sam-sung DA29-00020B Refrigerator Water Filter listing describes select Samsung French door and side-by-side refrigerators with the filter access inside the refrigerator. Its release method is the visual tell. A quarter turn to the left unlocks the cartridge, and no tool goes near it.
That listing names Samsung model RFG298HD directly and prices the cartridge at $37.99. It asks the household to replace the filter every 6 months.
Poseidon Filters covers the same position with a compatible cartridge at $19.99. The Gold Series GS-S2 Refrigerator Replacement Filter Fits Samsung HAF-CINS/ DA29-00020B listing prints the widest cross-reference in the Samsung line. It names DA29-00020A and DA29-00020B on the Samsung side. It also names HAF-CIN, HAF-CIN-EXP, HAFCIN and HAF-CINS, plus the Kenmore code 46-9101 and the older DA29-00019A.
Rated life on that Gold Series listing is 6 months or 300 gallons at 0.5 gallons per minute. The listing states the cartridge is NSF Certified and independently tested and verified.
The short round can: DA29-00003G and HAFCU1
The oldest family is a stubby cylinder. Samsung's own listing for that position describes refrigerators with short round filters and puts the cartridge at 5 1/2 inches long by 3 1/4 inches across. Set that beside the 8.86 inch HAF-QIN bar and the two are unmistakable in the hand.
The genuine Samsung cartridge for this position sits out of stock today. The Gold Series GS-S1 Refrigerator Replacement Filter Fits Samsung HAFCU1S/ DA29-00003G covers it at $19.99 and ships now.
The GS-S1 fit list reaches back through every code Samsung used for this cartridge. It names DA29-00003G along with DA29-00003A and DA29-00003B, then adds DA61-00159 and both HAFCU1 and HAFCU1S. An old round cartridge stamped with any of those points at this one position.
Why 00020A and 00020B are one purchase
Samsung revised this cartridge and moved the suffix from A to B. Two part numbers came out of one position, and a decade of printed manuals and appliance labels still carry the older letter.
The Gold Series GS-S2 listing resolves both in one line by naming DA29-00020A and DA29-00020B in the same fit list. A household reading 00020A off an old label orders the cartridge for 00020B and the housing accepts it.
The same logic covers the HAF-CIN codes. Samsung wrote that name four ways across production runs, and the GS-S2 fit list carries all four. Any spelling on an old barrel points at the interior twist position.
Reading the number when the old cartridge is gone
The shape check needs the spent filter in hand. Once that cartridge reaches the bin, three other places carry the same answer.
- The refrigerator owner manual lists the filter part in its maintenance section, and it keeps listing it for the life of the appliance.
- The model and serial plate inside the fresh food compartment gives the appliance model number. Samsung prints it on a sticker along the left wall or behind the crisper drawers on most cabinets.
- The bay itself often carries a small printed code beside the filter head. Look at it before the new cartridge goes in.
The Poseidon Filters team matches an appliance model to a cartridge at 855-789-3278. That call takes about a minute and it removes the two failure modes this category is known for. A household orders a cartridge that will not seat, or it orders one that seats in the housing while the dispenser keeps reporting the old filter.
Why Samsung cartridges answer to Kenmore numbers
Samsung built refrigerators sold under other badges, and the filter cross-references followed. The Gold Series GS-S2 listing prints the Kenmore code 46-9101 in the same fit list as DA29-00020B. It also carries the DA-97-08006A family of numbers, which appear on cabinets Samsung produced for other labels.
A shopper holding a Kenmore filter with a Samsung-shaped body is looking at one of those cabinets. The cross-reference on the Gold Series page settles it without any research into who built the appliance. Read the number, find it in the fit list, then order what that list covers.
Genuine or compatible on a Samsung cabinet
Both classes fit the same housings, and the difference a buyer should weigh sits in what each listing publishes.
- The genuine Samsung DA97-17376B at $28.99 publishes named NSF/ANSI standards. Its listing prints 401, 42 and 53 against the contaminants each standard covers.
- The Gold Series cartridges at $19.99 state that they are NSF Certified and independently tested and verified. Their listings stop short of naming standard numbers.
- The Gold Series line uses a catalytic coconut shell carbon block. Those listings name sand, silt, sediment, rust and chlorine taste among what the block reduces.
- The genuine Samsung DA29-00020B cartridge at $37.99 publishes neither a certification line nor a gallon rating. Its listing gives the fit and the six month window.
A household choosing on water quality reads the certification line on both pages and pays for the one it wants. A household swapping a cartridge in a rental or a break room reads the fit list and the price. Both answers are defensible, and the listings give a buyer enough to make the call without a phone call.
Flow rate, and what the HAF-QIN trades for it
Flow rate is the one Samsung number that moves against filtration. The HAF-QIN runs at 0.4 gallons per minute while the Gold Series cartridges run at 0.5. The HAF-QIN is also the only Samsung cartridge in the catalogue carrying NSF/ANSI 401 for emerging contaminants on its listing.
A household moving from an older Samsung cabinet to a HAF-QIN cabinet fills a glass more slowly. That difference is the certification showing up at the dispenser, and no faster cartridge exists for the HAF-QIN position.
A fill that has slowed since the last swap is a different problem. That one points at a cartridge nearing the end of its rated 300 gallons or at air still sitting in the line from a fresh install. Run several gallons through a new cartridge before judging it, because trapped air sputters and loose carbon fines cloud the first few glasses.
Rated life and the schedule that follows
Every Samsung cartridge in this catalogue publishes a six month window on its own listing. The HAF-QIN and both Gold Series cartridges add a 300 gallon ceiling to that window. Whichever limit arrives first is the one that governs.
A house on a well, or an office running a break-room dispenser through a hot summer, hits 300 gallons before six months. A two-person household on city water rarely does. The dispenser tells the truth either way.
An office manager stocking several appliances can settle them on one order. Poseidon Filters covers home and office refrigerators from the same catalogue, and a single plan can carry different cartridges on different schedules.
The Subscribe and Save page states the rule that makes a schedule work. Set the interval to the manufacturer's rated replacement window for the cartridge in the appliance. That page also publishes a standing 5 percent discount on every recurring shipment. On the $28.99 HAF-QIN that is $1.45 off each cartridge and one less date to remember. The guide to how the subscription plan works walks through the setup.
Frequently asked questions
How do I tell which Samsung water filter my refrigerator takes?
Look at the spent cartridge. A slim bar 8.86 inches long is the HAF-QIN. Samsung numbers that one DA97-17376B and it lists at $28.99. A cartridge that releases with a quarter turn inside the fresh food compartment belongs to the HAF-CIN family under part number DA29-00020B. A short round can 5 1/2 inches long belongs to the HAFCU1 family under part number DA29-00003G.
Is DA29-00020A the same as DA29-00020B?
They are one position under two part numbers. The Gold Series GS-S2 listing names DA29-00020A and DA29-00020B in the same fit list, along with every HAF-CIN spelling Samsung used. A label reading 00020A takes the cartridge sold for 00020B.
What does Poseidon Filters stock for the DA29-00020B position?
Two cartridges. The Sam-sung DA29-00020B Refrigerator Water Filter lists at $37.99, and the Gold Series GS-S2 compatible cartridge lists at $19.99. Both fit the same interior housing and release with the same quarter turn.
Is the Samsung HAF-QIN filter NSF certified?
The DA97-17376B listing states that the cartridge meets American National Standard NSF/ANSI 401 testing for emerging contaminants in drinking water. It adds that NSF International tested and certified the HAF-QIN cartridge to meet or exceed NSF/ANSI Standards 42 and 53.
How often does a Samsung refrigerator water filter need replacing?
The DA97-17376B listing rates the cartridge at 6 months or 300 gallons, whichever comes first. The Gold Series GS-S1 and GS-S2 listings publish the same figure. The genuine DA29-00020B listing asks for a swap every 6 months.
Hold the old cartridge up, then order
Samsung's part codes changed twice and its cartridge shapes did not. That is why the look wins. Read the shape off the spent filter, then match it to a row in the table above and order the cartridge that row names.
Current prices for the whole line sit in the Samsung refrigerator water filters collection, with the HAF-QIN at $28.99 and the Gold Series GS-S2 at $19.99 covering the two most common Samsung cabinets in American kitchens. A Subscribe and Save plan then carries the reorder on its own at 5 percent off every shipment.
A household running more than one brand can run the identical shape check elsewhere. The Whirlpool part number guide maps the legacy 4396xxx codes to their EveryDrop names, and the LG LT1000P guide settles the two LG cartridges that differ by two inches of length. An office manager restocking break-room appliances and return-air filters on one order will find the air-side sizing rules in the MERV 8 sizing guide. Anyone starting fresh across several systems can begin with the Poseidon Filters buying guide.
