Best Vietnamese Coffee Filters (Phin) for 2026: 6 Top Picks

By Juan Carlos Sosa | Boquete Coffee Traders

A Vietnamese coffee filter — the little metal drip pot called a phin — is the simplest, cheapest way to make a genuinely great cup of coffee at home. There is no paper, no power and almost nothing to go wrong: you spoon coffee into the chamber, add hot water, and let it drip slowly into your cup. Below are the best Vietnamese coffee filters I would actually buy, from a heavy specialty-grade stainless phin to the traditional made-in-Vietnam classic, plus how to brew a proper cup of cà phê sữa đá at the end.

What to look for in a phin

A Vietnamese coffee filter is about as simple as brewing gear gets — a chamber, a press disc and a lid — but a few details decide whether you get a clean, even cup or a slow, silty mess.

Material. Traditional phins are aluminum: cheap, light, quick to heat, and what you will find in most Vietnamese homes. Stainless steel costs a little more but holds heat better, resists denting and discoloring, is dishwasher-safe, and is usually machined to tighter tolerances — which means fewer grounds sneak into your cup. Both brew beautifully; stainless is the longer-term buy.

Insert type: gravity vs screw-press. The disc that sits on the grounds comes in two styles. A gravity insert simply rests on top and lets the coffee's own weight set the drip — traditional and foolproof. A screw-press insert threads down so you can tamp the grounds and dial the flow: tighter for a slower, stronger cup, looser for a faster one. Gravity is more authentic; a screw-press is more repeatable.

Size. A 4 to 8 oz phin makes one strong cup — perfect for a hot coffee. If you love Vietnamese iced coffee, size up to an 11 or 12 oz phin so you can brew a concentrated cup that will not vanish once it hits the ice and condensed milk.

Hole size and fit. Finer perforations give a cleaner cup but a slower drip; coarser ones are faster but let through more fines. And check that the chamber sits stably on a mug and a tall glass — you will want both.

The grind matters more than the filter. A phin wants a medium-coarse grind, roughly like coarse sand. Too fine and it clogs and drips forever; too coarse and it gushes and tastes thin. More on that below.

The 6 best Vietnamese coffee filters, reviewed

Best overall

1. Nguyen Coffee Supply Original Phin Filter (4 oz)

Nguyen Coffee Supply built its name on bringing Vietnamese coffee into the specialty world, and its stainless phin is the one I reach for first. The 4 oz chamber is sized for a single, properly strong cup, the heavy-gauge steel holds heat so the drip stays even, and the press plate is machined finely enough to give you a clean cup with almost no grounds slipping through. It brews in about five minutes and it will outlast every other filter here. If you want one phin done right, buy this one.

Material: Heavy stainless steel  |  Size: 4 oz (1 cup)  |  Best for: A lifetime everyday phin

Best traditional

2. Thang Long Gravity Phin (8 oz)

Thang Long has been making phin filters in Vietnam for decades, and this is the classic. It is a traditional gravity-insert phin: the coffee's own weight and a loose-fitting disc set the drip speed, so there is nothing to screw or adjust. You spoon in the grounds, rest the insert on top, add water and let gravity do the work — exactly the way it is done in a Saigon street cafe. The 8 oz size makes a strong cup with plenty of room for a layer of condensed milk underneath. Authentic, cheap and hard to beat for the money.

Material: Aluminum, made in Vietnam  |  Size: 8 oz  |  Best for: Authentic, traditional brewing

Best for consistency

3. Thang Long Screw-Press Phin (8 oz)

If your phin coffee comes out different every time, a screw-down press fixes it. Instead of a loose gravity disc, this Thang Long has a threaded insert you tighten onto the grounds, so you control the tamp — and therefore the drip speed — precisely. Screw it lighter for a faster, brighter cup, or firmer for a slow, syrupy one. It is the most repeatable phin here, and my pick if you like dialing a brew in until it is exactly right.

Material: Aluminum, screw-down insert  |  Size: 8 oz  |  Best for: Repeatable, controllable brewing

Best for iced coffee

4. Nguyen 12 oz Phin

Cà phê sữa đá — Vietnamese iced coffee — needs a bigger, stronger brew to survive being poured over ice, and that is where this 12 oz Nguyen phin earns its place. The larger chamber lets you brew a concentrated cup straight down onto a glass of sweetened condensed milk, so it stays bold once the ice melts instead of turning watery. It is the same heavy stainless build as the 4 oz, just scaled up for the drink most people fall in love with first.

Material: Heavy stainless steel  |  Size: 12 oz  |  Best for: Vietnamese iced coffee

Best budget

5. Thang Long Small Stainless Phin (6 oz)

You do not need to spend much to try phin coffee, and this small 6 oz Thang Long is the cheapest way in that I would still stand behind. It is stainless steel rather than the flimsier aluminum you find at the very bottom of the market, it is made by the same Vietnamese maker as our traditional pick, and the single-cup size is just right for one strong coffee. A great first phin, or a spare to keep at the office.

Material: Stainless steel  |  Size: 6 oz (1 cup)  |  Best for: The cheapest phin worth buying

Best for travel

6. Portable Phin with Built-in Cup

This one packs the whole brew into a single stainless unit: the phin sits on its own cup with a lid, so you brew and drink from the same vessel at a campsite, a desk or a hotel room. There is no glass to break and nothing extra to carry, which makes it the most self-contained option here. It makes a smaller cup than a full-size phin, but for good coffee on the move it is exactly what you want in a bag.

Material: Stainless steel, built-in cup  |  Size: Single serve  |  Best for: Travel and camping

Which phin should you choose?

For most people I would buy the Nguyen Original Phin — the heavy stainless build and clean cup make it worth the few extra dollars, and it will last for years. If you want the real, traditional article for very little money, the Thang Long gravity phin is the genuine made-in-Vietnam classic. If you like control and repeatability, the screw-press Thang Long lets you dial the drip. Drinking mostly iced? Size up to the 12 oz Nguyen. Just curious and want to spend as little as possible? The budget Thang Long phin gets you brewing today. And if you travel, the all-in-one portable phin goes in the bag.

How to make Vietnamese coffee with a phin

A phin is genuinely hard to mess up, but these few steps get you a rich, sweet cup every time — and a real cà phê sữa đá if you want it iced.

1. Grind medium-coarse. Aim for something like coarse sand or raw sugar — coarser than drip. Too fine and the phin clogs and drips forever; too coarse and it gushes and tastes thin. This is the single biggest thing that decides your cup.

2. Add coffee and level it. Spoon about 2 to 3 tablespoons of ground coffee into the chamber, give it a gentle shake to level, and set the insert on top (or thread the screw-press down lightly — snug, not cranked).

3. Bloom. Set the phin on your cup or glass and pour a small splash of just-off-boil water (about 200F) over the grounds. Wait 30 seconds for them to swell and release gas — this is what gives you a fuller cup.

4. Fill and drip. Top up with hot water, put the lid on, and let it drip for 4 to 5 minutes. If it races through, your grind is too coarse or the press is too loose; if it stalls, go coarser or loosen the press.

5. Make it cà phê sữa đá. For classic Vietnamese iced coffee, brew directly over 2 to 3 tablespoons of sweetened condensed milk in a glass, stir until it dissolves, then pour the lot over a tall glass of ice. For a hot cup, skip the ice and drink it as cà phê sữa nóng.

One thing worth saying: the phin is only half the cup. Vietnamese coffee is strong and often taken with sweet condensed milk, so it wants a bold, chocolatey roast with real body — the kind of coffee that pushes through the sugar instead of disappearing under it.

Vietnamese coffee filter FAQ

What is a Vietnamese coffee filter called?
It is called a phin (phin cà phê). You will also see it sold as a "Vietnamese coffee maker," "Vietnamese coffee press" or simply a "phin filter" — they all mean the same little metal drip pot that sits on top of your cup.

Do I need special Vietnamese coffee for a phin?
No. Traditional Vietnamese coffee is a dark robusta blend, but a phin will brew any coffee well. Because the cup is strong and often sweetened, it shines with a bold, chocolatey roast — a medium-to-dark specialty coffee like our Cafe Palo Alto works beautifully, ground medium-coarse.

What grind do I use in a phin?
Medium-coarse, roughly like coarse sand — coarser than a drip machine. A grind that is too fine clogs the filter and drips endlessly; too coarse and the water rushes through and the cup tastes weak.

Aluminum or stainless steel phin?
Aluminum is the traditional, inexpensive choice — light and quick to heat, but it can dent and discolor over time. Stainless steel costs a little more but holds heat better, lasts longer, is dishwasher-safe, and is usually machined tighter so fewer grounds reach your cup.

What size phin should I buy?
A 4 to 8 oz phin makes one strong hot cup. If you mostly want Vietnamese iced coffee with condensed milk, choose an 11 or 12 oz phin so the brew stays bold after it hits the ice.
