Moka Pot Filter Paper: Do You Need One? Pros, Cons & Taste Test

A moka pot filter paper is optional — but it changes the coffee. A thin paper disc sits on top of the coffee grounds in the filter basket. It catches micro-fines and oils that the metal filter cannot. The result is cleaner, smoother coffee with less body. Here is whether that trade-off is worth it for you.

"Moka Pot Filter" Can Mean Three Different Parts

A moka pot has two filters built in, and the paper disc is a third, optional one. People search "moka pot filter" meaning any of them, so here is the difference before anything else.

• The funnel basket: the metal cup that holds the coffee grounds. It sits in the water chamber.
• The filter plate: the flat metal screen in the upper chamber, held by the rubber gasket. This is the part that clogs and the part you replace with the gasket.
• The paper filter: a thin disc you add on top of the grounds. Optional. This page is about that one.

If your coffee is coming out slow or muddy, the part you want is the filter plate and gasket, not paper. See our moka pot accessories guide for replacements.

What Does a Paper Filter Do in a Moka Pot?

A standard moka pot uses only a metal filter plate with tiny holes. This lets through two things that paper catches:

• Micro-fines — tiny coffee particles smaller than the metal filter holes. These create the slight sludge at the bottom of a moka pot cup. Paper catches them.
• Coffee oils (cafestol and kahweol) — these oils give moka pot coffee its rich, thick body. Paper absorbs a significant portion of them.

Whether you want those oils in your cup is a matter of personal taste. Some people love the thick, oily body of unfiltered moka pot coffee. Others prefer a cleaner, lighter cup. The paper filter gives you the second option.

Paper Filter Pros and Cons

Taste Test: With vs Without Paper Filter

I ran a side-by-side test with the InstaCuppa Aluminum Moka Pot. Same beans, Araku Valley medium roast. Same grind, medium-fine. Same water, hot from a kettle.

Without paper filter:

• Thick, full body with an oily mouthfeel
• Bold, chocolatey flavour with low acidity
• Thin layer of sludge at the bottom of the cup (normal)
• Classic moka pot taste — strong and rich

With paper filter (AeroPress paper, trimmed to fit):

• Noticeably lighter body — more like a strong drip coffee
• Fruit and citrus notes more prominent
• Zero sediment — completely clean cup
• Less "espresso-like", more "pour-over-like"

My personal preference: without paper. I like the thick body and oily richness of a traditional moka pot brew. But if you are coming from pour-over or drip coffee and find moka pot coffee too heavy, the paper filter bridges the gap nicely.

The Cholesterol Angle — Does It Matter?

Where the numbers come from: A Nestlé Research Centre team measured cafestol in real brews. They reported it plainly:

"Scandinavian-style boiled coffee and Turkish-style coffee contained the highest amounts, equivalent to 7.2 and 5.3 mg cafestol per cup... In contrast, instant and drip-filtered coffee brews contained negligible amounts of these diterpenes, and espresso coffee contained intermediate amounts, about 1 mg cafestol and 1 mg kahweol per cup."
— Gross, Jaccaud & Huggett, Food and Chemical Toxicology, 1997

A later Brazilian study ranked the brews by how much diterpene they pull through. Boiled came highest. Then French press, then moka, then Turkish. Paper-filtered was lowest — Novaes et al., Plants, 2023. Paper-filtered brews measured 1.62 to 2.98 mg of cafestol a litre — Rendón et al., Food Research International, 2018.

How much cafestol actually moves cholesterol: In one trial, 10 men took about 60 mg of pure cafestol a day. They did this for 28 days. Their LDL rose by 0.57 mmol/L, or about 22 mg/dL. The effect tracked the dose — Urgert et al., American Journal of Clinical Nutrition, 1997. That daily dose is a long way from a moka cup at roughly 1 mg.

The population evidence: A Norwegian study followed 508,747 men and women. It ran for about 20 years. Unfiltered brew was linked to higher death rates than filtered brew. The raised risk showed up most in people drinking 9 or more cups of unfiltered coffee a day. It also showed up in men aged 60 and over — Tverdal et al., European Journal of Preventive Cardiology, 2020.

If you drink 1 or 2 cups of moka pot coffee a day, which is most people, the cafestol load is small. Paper is a cheap precaution if you have high cholesterol. Same if heart disease runs in your family, or you drink several cups a day.

This is not medical advice. Talk to your doctor if cholesterol is a concern. The point is simple. The paper option exists, and it costs about Rs 1 a brew.

How to Use a Paper Filter in a Moka Pot

1. Get the right size paper — measure your moka pot filter basket diameter. Most 3-cup pots need a ~57-62mm disc. AeroPress papers (62mm) work for most 3-cup moka pots.
2. Fill the basket with coffee grounds as normal — level off the top without pressing down.
3. Place the paper disc on top of the grounds — it should sit flat. Some people wet the paper first (like pour-over). I find it does not make a noticeable difference with moka pots.
4. Assemble and brew as normal — the paper does not change the process. Brewing takes about 10-15 seconds longer because water passes through an extra layer.
5. After brewing, the paper lifts out with the coffee puck — cleanup is actually easier. The puck comes out in one clean disc instead of loose grounds.

Where to Buy Moka Pot Filter Papers in India

The most practical route for Indian buyers: buy an AeroPress filter pack on Amazon India. At Rs 200-400 for 350 papers, each paper costs about Rs 1. That is the cheapest and most available option.

Do not use regular printer paper, tissue paper, or paper towels. Only food-safe, unbleached coffee filter paper is suitable. Regular paper can contain chemicals and bleaching agents that you do not want in your coffee.
