Pick paper if you want a clean, bright cup that shows off a coffee’s origin, and if you want the easiest cleanup. Pick metal if you want a heavier, rounder cup and a filter you can wash and reuse for years. Both make good coffee. The difference is what each one lets into your mug, and that is also where the one health point worth knowing comes in.
Below we compare paper, metal mesh and cloth on flavor, flow, cleanup, cost and cholesterol. We also match each to the brewer you own.
TL;DR
- Paper removes most oils and fine particles, so the cup tastes clean, light and delicate. Metal lets them through for more body and texture.
- In America’s Test Kitchen’s panel test, paper and metal brews were virtually identical in flavor. The metal cup had more body and tasted ever so slightly weaker.
- Metal needs a slightly finer grind and a rinse after every brew. Paper is more forgiving and you just throw it away.
- If you drink several cups a day and watch your LDL cholesterol, paper is the filter that removes the compounds involved. Ask your doctor if you have a specific concern.
- Light, fruity single origins tend to shine in paper. Bold, dark blends tend to suit metal.

What actually separates the two filters
A filter does one job: it holds back grounds. How much else it holds back decides the cup.
Paper is a dense web of fibers. According to Coffee Gear Guides, it traps particles down to single-digit microns. Metal mesh has pores of roughly 20 to 100 microns, depending on how dense the mesh is. That gap is large enough for coffee oils and very fine particles to pass.
The oils matter because they carry flavor. As Takumi Brewing Lab explains, coffee oils hold fat-soluble flavor compounds and add body and mouthfeel. Paper removes most of them, while metal and cloth let them through. More oil means more texture and a heavier feel on the palate.
The fine particles that slip through a metal filter settle at the bottom of the cup. Takumi notes that they keep extracting after the brew and can add bitterness the longer the cup sits. That is why a metal-filtered cup can taste thick at the start and a little muddy at the bottom.
Taste: clarity versus body
Sprudge puts the choice down to two factors: the cup profile you want and how easy the filter is to use. Larger holes let more oils and solids through for a weightier mouthfeel. Paper cups are usually described as clean, light or delicate.
In practice, here is what you can expect:
- Paper: defined acidity, clear fruit and floral notes, a tea-like finish. The cup looks bright and translucent.
- Metal: a fuller, rounder, slightly oily cup. Flavors blend together more and the finish lingers.
- Cloth: in between. Brighter than metal, richer than paper.
The America’s Test Kitchen result is a useful reality check. In their blind comparison the flavors were virtually identical and the main difference was body. If you are not chasing subtle notes, you may not taste a dramatic gap. If you brew a delicate light roast and pay attention, you will notice the texture difference first.
What this means for your beans
Paper filters trap diterpenes, which according to Know Your Grinder lets origin character, stone fruit, florals and bright acidity stand out. The same page notes that paper is the standard in specialty coffee competitions. Metal gives a fuller, more textured cup that suits bold dark-roasted blends.
A simple rule: the more delicate and distinctive the coffee, the more a paper filter helps you taste what makes it special. The heavier the roast, the more a metal filter’s body complements it.
Flow, grind size and brewing method
The filter changes how fast water moves, and that changes extraction.
In the independent timing set cited by Coffee Gear Guides, 300 g of water ran through the same dripper with each filter. The papers landed between roughly 5.8 and 15.3 mL/s, cloth was near 18 mL/s, and metal reached about 68 mL/s. Metal moved water four to twelve times faster than the papers measured beside it.
Fast flow means less contact time. Left unchanged, that gives a thin, sour or under-extracted cup. The fixes are simple:
- Grind finer. America’s Test Kitchen recommends grinding a little finer with a metal filter because water passes through faster.
- Or slow your pour. Pour in smaller increments to extend contact time.
- Keep the dose steady. Change one variable at a time so you know what helped.
Paper is more forgiving on this front. A wider grind range still gives a balanced extraction. The flip side, noted by Sprudge’s Zac Cadwalader, is that thick paper filters such as Chemex-style ones can clog, and small changes in how you pour can change brew time a lot. Larger holes tend to give more consistent results, in his view.
If you want a refresher on matching grind to method, our guide to grind size for each brew method walks through it, and our page on understanding different coffee grinds covers the basics.
Which filter fits which brewer
| Brewer | Paper | Metal | Cloth |
|---|---|---|---|
| Hario V60 | Standard choice | Some setups, such as the Kone Mini | Less common |
| Chemex | Standard choice, thicker paper | Kone for compatible large-format brewers | Less common |
| Kalita Wave | Standard choice | Less common | Less common |
| AeroPress | Yes | Yes, stainless disc | Not typical |
| Automatic drip machine | Yes | Yes, reusable basket | Traditional drip |
| French press, percolator, moka pot | Not used | Built in | Not used |
| Siphon and cold brew | Possible | Possible | Best fit |
The brewer pairings come from Sprudge, Fellow and Takumi. The practical lesson is to choose a filter shape made for your brewer. A filter that does not fit lets grounds bypass it or changes the flow in ways you cannot control.
If you are deciding between brewers as well, our piece on AeroPress vs pour over compares the two with tested recipes.
A note on AeroPress and gold-tone filters
The AeroPress is the easiest place to try both, because the filters are cheap and interchangeable. AeroPress says its stainless steel filter has 178-micron holes, does not absorb oils or withhold fines, and adds texture and body. For espresso-style brewing with the metal filter, it suggests a grind of 300 to 500 microns. Paper absorbs oils and catches fine particles for a cleaner cup.
There is also a middle option. AeroPress says its titanium-coated Gold Tone filter has smaller holes that hold back more grit. The result is the rich body of a metal-filtered brew with more delicacy and clarity.
Cleanup and upkeep
This is where the two filters feel most different day to day.
Paper is single use. Remove it, toss it with the grounds, and you are done. Rinse natural or unbleached paper with hot water first to reduce any cardboard taste, as Sprudge advises.
Metal needs a little discipline. According to Coffee Gear Guides, rinse it under hot water right after each brew, before the oils cool and oxidize. Do a weekly soak in hot water with mild detergent or diluted vinegar for 10 to 20 minutes, and a monthly deep clean with sodium percarbonate. The National Coffee Association, as cited there, notes that metal filters must be cleaned thoroughly so lingering oils do not affect the next brew’s taste.
Cloth is the most demanding. Takumi says to store it submerged in clean cold water in a sealed container in the refrigerator. Never let it dry out, because a dry cloth filter can develop a musty, rancid character that is almost impossible to remove. Replace it every two to three months with regular use.
Be honest with yourself about your mornings. If you brew once a day and want zero fuss, paper wins. If you do not mind a 30-second rinse, metal is easy to live with.
Cost and environmental footprint
Metal costs more upfront and less over time. Fellow puts metal filters at $20 to $50 depending on brand, package and level of filtration, and says they last years. That makes them more cost-effective in the long run than disposable paper.
On the environmental side, Reencle reports that unbleached brown paper and oxygen-bleached white paper break down readily in a compost pile. Chlorine-bleached white paper is technically compostable but may leave trace residues. Metal is not compostable, but the same source considers it the best option overall for the environment because you reuse it.
If you compost your grounds, paper filters can go in with them. That makes paper a low-waste choice too, so this one comes down to your habits rather than a clear winner.
Is a metal filter healthier than paper?
This is the question people search most, and it has a clear answer on one point: cholesterol.
Coffee contains two oily compounds, cafestol and kahweol. Paper filters catch most of them. Metal and cloth let them through. The compounds can raise LDL cholesterol.
The evidence:
- An early Dutch study of 64 healthy volunteers found that six cups a day of unfiltered boiled coffee for 79 days raised total cholesterol by 0.42 mmol/L (16 mg/dL) and LDL by 0.41 mmol/L (16 mg/dL). Boiled coffee that was then paper-filtered showed no significant lipid effects.
- A 2025 study by Iggman and colleagues, reported by Healio, found that workplace brewing machines with metal filters had median cafestol levels of 175.7 mg/L. The researchers estimated that swapping three daily cups of that coffee for paper-filtered coffee could lower LDL by 0.58 mmol/L.
- Women’s Health reported on the same study and quoted a cardiologist, Dr. Cheng-Han Chen, saying certain office machines use metal filters that do not remove diterpenes as effectively.
- Empirical Health’s review of the research says the effect is concentrated in unfiltered coffee and grows with dose. It also notes that a metal mesh or cloth lets the oils through, so only paper gives the cholesterol benefit.
What to do with this: if you drink one or two cups a day, the effect is small. If you drink several cups daily from a metal filter, French press or percolator, or if you have high LDL cholesterol or heart disease risk, ask your doctor or a registered dietitian whether paper-filtered coffee makes sense for you. For most healthy people, the metal-versus-paper choice is about taste and convenience first.
A quick way to choose
Choose paper if you:
- brew light or medium roasts and single origins
- want a clean, bright, tea-like cup
- drink several cups daily and want to limit diterpenes
- want no cleanup beyond the compost bin
Choose metal if you:
- like a full, rounder, more textured cup
- brew darker roasts or bold blends
- want to stop buying filters
- are happy to grind a bit finer and rinse after each brew
Choose cloth if you:
- brew with a siphon, traditional drip or cold brew
- enjoy aromatic cups and will keep up the storage routine
You can also own both. Many home brewers keep paper for weekday light roasts and a metal filter for a weekend dark roast.
Our perspective
We roast fresh to order and source with full traceability from regions like Colombia, Peru, Bali and Uganda. We want you to taste where a coffee comes from.
That is why we lean toward paper for our single origins. A clean filter lets the fruit, florals and acidity of a washed Colombian or a Peruvian lot come through without extra oil blurring the edges. If you love a heavier cup, a metal filter and a slightly finer grind will serve our bolder blends beautifully.
Whatever you choose, the beans and the grind matter just as much as the filter. Fresh roast and the right grind for your brewer will improve your cup more than any filter swap.

Find your beans
Once your filter is sorted, match it to the coffee. If you are on paper and want clarity, start with our single origin coffees. If you prefer metal and body, try a bold blend such as our House Blend or 6 Bean Blend. Not sure where to begin? The Single Origin Favorites Sample Pack lets you taste several origins through the same filter and compare.
FAQ
Which coffee filter is best?
There is no single best filter, only the best match for your brewer and the cup you like. Paper gives a clean, bright cup and is the easiest to use. Metal gives more body and lasts for years.
Can you put a paper filter in a metal filter?
It depends on the brewer. On an AeroPress you can use a paper filter in place of the metal disc, but the two are alternatives, so you get one result or the other. Stacking them in a drip basket mostly slows flow and gives a paper-filtered cup, since the paper does the filtering.
Is cloth better than paper?
Cloth gives a cup between the two: brighter than metal, richer than paper. It needs more care, including cold-water storage in the fridge and replacement every two to three months. It is a good fit for siphon, traditional drip and cold brew.
Do I need to change my grind with a metal filter?
Usually, yes. Water moves through metal much faster than through paper, so America’s Test Kitchen recommends grinding a little finer. If the cup tastes thin or sour, go finer or pour more slowly.
Is a metal filter bad for cholesterol?
Metal filters let cafestol and kahweol into the cup, and these compounds can raise LDL cholesterol, mainly with heavy daily intake. If you have high cholesterol or heart disease risk, talk to your doctor about paper-filtered coffee.
