Water Filters FAST carries three Samsung refrigerator water filter families. The DA29-00020B family answers to twenty different part numbers, more than either of the other two. The store stocks that filter two ways, and the Samsung part costs $37.99 while the Gold Series GS-S2 costs $19.99.

Both cartridges run a six month interval and the Gold Series carries NSF certification. The gap between them is $18.00 a cartridge.

This page lists every Samsung number the GS-S2 answers to, prints its specifications, and shows what the two options cost across three years.

Every Samsung number the GS-S2 covers

Samsung numbers this filter more ways than any other cartridge in the catalog. The Gold Series GS-S2 listing names all of them.

The DA29 numbers come first. DA29-00020A, DA29-00020B, DA29-00019A, DA2900019A, DA2900020A, and DA2900020B all point at this cartridge.

The HAF numbers come next. HAF-CIN, HAF-CINS, HAF-CIN-EXP, HAF-CINEXP, and HAFCIN are Samsung's model names for the same part.

The DA97 group covers Samsung's service numbering. DA-97-08006A, DA-97-08006A-B, DA-97-08006B, and DA97-08006A-B belong here.

A short numeric family closes the list. 9101, 09101, 46-9101, 469101, and 04609101000 appear on retail packaging and on parts diagrams.

Any of those twenty strings buys the same filter. A shopper holding one of them has found the right page.

Where Samsung prints the number

Samsung prints the part number on the cartridge body near the cap. Pull the old filter and turn it under a light.

The refrigerator's model sticker is the backup. Open the fresh food compartment and look along the left wall or under the crisper drawers.

Filter position narrows it further. This family installs inside the refrigerator compartment, and Samsung's own listing describes the removal as a quarter turn to the left.

A filter that sits in the base grille or behind a door panel belongs to a different Samsung family. Call 855-789-FAST with the model number when the position does not match.

What the GS-S2 is built from

The Gold Series line runs on coconut shell carbon block. Catalytic coconut shell carbon reduces sand, silt, sediment, rust, and chlorine taste and odor.

NSF certified the cartridge after independent testing. Gold Series builds it in the United States.

Gold Series is the Water Filters FAST house line. The store puts its own name on these cartridges and answers the phone when one of them raises a question.

Three hundred gallons is the figure worth noting. A four person household drinking and making ice off the dispenser runs through roughly that much in half a year.

Pressure is the other figure to check. The cartridge needs at least 30 psi at the refrigerator and tops out at 100 psi. A house on a well with a pump switch set low can sit under that floor at the end of a draw cycle, and the dispenser runs slowly for reasons the filter never caused.

The Samsung part and the price gap

Water Filters FAST also stocks the Samsung DA29-00020B refrigerator water filter at $37.99. Samsung sets the same six month interval on it.

The Samsung listing describes a slim body and a tool-free swap. It fits Samsung French door and side by side refrigerators with the filter access inside the refrigerator, including model RFG298HD.

Three years of filters costs $114.99 in the Gold Series 6 Pack. Six Samsung cartridges bought one at a time total $227.94. The difference across those three years is $112.95.

The Gold Series 6 Pack works out to $19.17 a cartridge and clears the $75 free shipping line on its own.

Which one to buy

Both filters answer the same fit list and both change at six months. Price is the thing separating them.

Buy the Samsung part when you want the manufacturer cartridge in the housing. Plenty of owners prefer that on a newer refrigerator.

Buy the Gold Series GS-S2 when price leads the decision. Eighteen dollars a cartridge adds up fast in a house that runs two refrigerators.

Buy in a 6 Pack either way when the price per cartridge matters. A wrapped filter keeps indefinitely until water reaches the carbon.

The other Samsung filter families

Two more Samsung families cover the refrigerators the DA29-00020B does not.

The DA29-00003G family is the older one. Samsung also badges it HAFCU1S, and the Gold Series GS-S1 covers it at $19.99. Its fit list includes DA29-00003A, DA29-00003B, DA61-00159, DA61-00159A, and HAFCU1.

The DA97-17376B family covers another set of Samsung models. Samsung badges it HAF-QIN and HAFQIN/EXP, and Water Filters FAST stocks a replacement at $28.99.

Three families, three cartridges, and no crossover between them. Read the number off the old cartridge before ordering. A refrigerator's build year is a poor guide here.

What a carbon block cartridge handles

A carbon block works two ways at once. The block traps particles too large to pass through its pores, and the carbon itself holds onto chemicals as the water moves by.

Chlorine is the headline job. Municipal systems dose chlorine to keep the distribution line safe, and that dose is what most people taste in a glass of tap water. Carbon strips it out and the water starts tasting like water again.

Particles are the other job. Sand, silt, rust, and scale flakes come loose from old plumbing, and the block catches them before they reach the ice maker.

Some things pass straight through. A refrigerator carbon filter is not built to remove dissolved minerals, and hard water stays hard on the other side of it. Water carrying heavy iron or a sulfur smell needs treatment upstream of the refrigerator.

Bacteria are outside its scope as well. A refrigerator cartridge treats water that arrives safe and makes it taste better.

Test the incoming water when a new cartridge changes nothing. A problem the filter cannot see is a problem no cartridge will fix.

Changing a Samsung water filter

Locate the filter inside the fresh food compartment. Samsung mounts this family in the upper right corner on most models.

Turn the cartridge a quarter turn to the left and pull it straight out. A small amount of water sits in the housing, so keep a cloth underneath.

Push the new cartridge in and turn it a quarter turn to the right until it seats. The cap should finish flush with the housing.

Run about two gallons through the dispenser before drinking. Fresh carbon releases a fine grey dust on the first draw and the flush clears it out.

Hold the filter reset button on the dispenser panel for three seconds afterward. Samsung uses different button labels across panels, and the owner manual names the right one.

Signs the cartridge is spent

Flow drops first. A dispenser that filled a glass in ten seconds starts taking twenty.

Ice production falls off next. The ice maker draws through the same cartridge and it loses ground before anybody notices the dispenser.

Taste returns third. Chlorine comes back to the water and the cubes turn cloudy.

Change on six months and let the other signs confirm it. Write the install date on the cap with a marker before the cartridge goes in.

Ordering and shipping
