The basic steps to swap out your Samsung fridge filter

Most Samsung refrigerators use a twist-and-lock or push-button filter cartridge that you can replace yourself in under five minutes without tools. The filter sits either inside the fridge (usually in the upper right corner or back wall) or underneath the fridge near the front grille. You turn or push the old filter out, insert the new one, and run water through the dispenser for 30 seconds to clear air from the line.

The exact location and removal method depend on your model. Samsung makes several filter types — the most common are the DA29-00003G (twist-type), DA29-00035B (push-button), and HAF-CIN (side-mounted). You can find your model number on the back wall of your fridge or in your owner's manual, then match it to the right filter before you start.

Replacing the filter yourself costs between $30 and $60 for a genuine Samsung cartridge, depending on the model. A service call to have someone else do it runs $150 to $300 before the filter cost. The filter should be replaced every six months if you use the ice maker and water dispenser regularly, or every 12 months with light use.

Key Takeaways

  • Samsung fridge filters are located either inside the refrigerator compartment or under the front grille, and removal takes less than five minutes with no tools required.
  • The three most common Samsung filter types are twist-and-lock (DA29-00003G), push-button (DA29-00035B), and side-mounted (HAF-CIN), and you must match your model number to buy the correct replacement.
  • After inserting the new filter, run water through the dispenser for 30 seconds to purge air from the line and prevent sputtering or cloudy ice.
  • Genuine Samsung filters cost $30 to $60 and should be replaced every six to twelve months depending on how often you use the water and ice features.

Finding your filter location and model number

Open your refrigerator and look in the upper right corner of the interior, along the back wall, or inside the bottom left corner of the fridge compartment. If you do not see a filter cartridge inside, it is mounted underneath the fridge near the front grille — you will need to get down and look under the front panel or remove a small access door.

Write down your refrigerator's model number before you shop for a replacement filter. The model number is printed on a sticker on the back wall of the fridge, usually near the top, or inside the owner's manual. It starts with letters like RF, RS, or RH followed by numbers. Take a photo of the sticker with your phone so you have it when you order online or visit a store.

Once you have the model number, search for "[your model number] water filter" on the Samsung website or a retailer like Amazon or Best Buy. The search results will show you the exact filter type your fridge uses and confirm the price. Do not guess — buying the wrong filter means a wasted trip and a return.

Removing the old filter

If your filter is a twist-and-lock type (the most common), locate the cartridge inside the fridge and grip it firmly. Turn it counterclockwise (to the left) about a quarter turn until you feel it stop. Pull it straight out toward you. Some water may drip, so have a towel or small cup ready underneath.

If your filter is a push-button type, press the button or lever on the filter cartridge and it will pop out or swing down. Catch it as it comes out and set it aside. Again, a small amount of water may spill.

If your filter is side-mounted (usually on the right side of the fridge interior), you may need to turn a knob or press a release tab. Check your owner's manual for the exact motion — it varies by model. Once released, the cartridge should slide or swing out easily.

Do not force any filter. If it does not turn or pop out smoothly, stop and consult your manual or call Samsung customer service at 1-800-726-7864 rather than risk cracking the housing.

Installing the new filter

Remove the new filter from its packaging and inspect the rubber gasket (the seal) at the end. If it looks cracked or dry, do not use it — contact the seller for a replacement. The gasket must be intact or water will leak around the filter.

For twist-and-lock filters, align the cartridge with the housing opening and push it in straight until it seats. Then turn it clockwise (to the right) about a quarter turn until it stops. You should hear or feel a click when it locks. Do not over-tighten — a quarter turn is enough.

For push-button filters, slide the new cartridge into the slot and push until it clicks into place. The button should be flush with the housing when locked.

For side-mounted filters, slide the cartridge into the slot and turn the knob or press the tab to lock it, following the reverse of the removal steps.

Flushing the line and testing the dispenser

After the new filter is locked in place, go to the water dispenser on your fridge door and run water for 30 seconds into a sink or large cup. This flushes air from the filter and line. The water may come out cloudy or with a slight hissing sound — this is normal and will stop after a few seconds.

If you have an ice maker, run it once and discard the first batch of ice. The ice may taste slightly off or look cloudy until the filter has been running for a few hours. This is normal and clears up on its own.

If water does not flow at all after 30 seconds of flushing, or if it leaks around the filter housing, turn off the water supply to the fridge (usually a valve under the sink or behind the fridge) and check that the filter is fully locked. Unlock it, reseat it, and lock it again. If the problem persists, the gasket may be damaged or the filter may be the wrong type for your model.

When to replace your filter and what to watch for

Samsung recommends replacing the filter every six months if you use the ice maker and water dispenser daily. If you use them only occasionally, every 12 months is usually sufficient. Mark the date on your calendar or set a phone reminder when you install a new filter so you do not forget.

Some Samsung models have a filter indicator light on the fridge display that turns on when the filter is due for replacement. If your fridge has this feature, the light will change color (usually from blue to red) when the cartridge has been in use for six months. This is a reminder, not a hard cutoff — the filter will continue to work, but its ability to remove contaminants declines.

If your water tastes off, the ice smells strange, or the water flow from the dispenser slows down noticeably, the filter may be clogged before the six-month mark. This can happen if your tap water has high sediment or mineral content. Replace it early if you notice these signs.

Buying the right replacement filter

Genuine Samsung filters are sold at Best Buy, Amazon, Lowe's, Home Depot, and directly from Samsung. Prices range from $30 to $60 depending on the model. Third-party filters that claim to fit Samsung fridges are cheaper (often $15 to $25) but may not filter as effectively or fit as snugly. If you choose a third-party filter, check the reviews for your specific model number to see if other users report leaks or poor fit.

Buy your filter before the old one fails so you have it on hand when replacement time comes. Ordering online and having it shipped takes a few days, so plan ahead. If you need a filter when ready and do not know your model number, take your fridge's model sticker to a local appliance parts store and they can match it for you on the spot.

Frequently Asked Questions

Can I use a third-party filter instead of a Samsung brand filter?

Yes, but check the reviews for your specific model first. Third-party filters are cheaper but may not seal as tightly or filter as well. Some users report leaks or poor water flow. If you choose a non-Samsung filter, buy from a seller with a return policy in case it does not fit properly.

What do I do if water leaks around the filter after I install it?

Turn off the water supply to the fridge, unlock the filter, and remove it. Inspect the rubber gasket for cracks or debris. Wipe the gasket and the housing opening clean with a dry cloth, then reinstall the filter and lock it firmly. If it still leaks, the gasket may be damaged — contact the seller for a replacement cartridge.

How long does it take to replace a Samsung fridge filter?

The actual replacement takes three to five minutes. Flushing the line afterward takes another 30 seconds. The entire job, including finding your model number and buying the filter, takes less than an hour if you already have the replacement on hand.

Do I need to turn off the water supply before replacing the filter?

No. A small amount of water will drip when you remove the old filter, but you do not need to shut off the main water valve. Have a towel ready to catch the drips. Only turn off the water supply if the filter leaks after installation and you need to remove it again.

Why is my water cloudy after I install a new filter?

Air trapped in the filter and line comes out as tiny bubbles, making the water look cloudy. Run water through the dispenser for 30 seconds and the cloudiness will clear. If it persists after several minutes, the filter may not be seated correctly — unlock it and reseat it firmly.
