Tiamo Stainless Steel K-Series Pour-Over Filters Explained

If you’ve ever poured water over coffee grounds and ended up with either weak, underwhelming results or bitter over-extraction, you’re not alone. Many home brewers struggle to get consistent flavor, especially when factors like filter material, water flow rate, and brewer design aren’t dialed in. The right filter can make a surprising difference.

In short: Tiamo’s K01 and K02 stainless steel pour-over filters come in two sizes—1–2 people (K01) and 3–4 people (K02)—and their three-hole base, sloped interior, and anti-stick design help control brew speed, clarity, and strength depending on how quickly you pour.

What Is the Tiamo K01 and K02?

The Tiamo K01 and K02 are stainless steel pour-over coffee filters made for manual drip brewing. They’re designed by CAFEDETIAMO and come in two sizes: the K01 is for 1–2 cups, while the K02 is for 3–4 cups. Both feature a unique three-hole bottom for controlled extraction, a sloped interior that allows air to escape and prevents filter paper from sticking, and a built-in design that supports full coffee bed expansion.

Design Features That Affect Your Brew

The Tiamo K-series filters aren’t just metal cones—they include engineering details that influence how your coffee tastes:

• Three-Hole Base: Allows unrestricted downward flow for cleaner, more balanced extraction.
• Sloped Interior Wall: Promotes even water flow and prevents the filter from sealing against the brewer, ensuring better airflow.
• Non-Stick Surface Design: Filter paper stays in place even when wet, aiding consistent saturation.
• Coffee Expansion Space: The wide, open cone design gives coffee grounds room to bloom without restriction.

These features mean that pouring slowly tends to produce a lighter, gentler cup, while a faster pour yields a richer, more intense brew. The filter doesn’t dictate flavor on its own—it works with your technique.

Why Filter Choice Matters in Pour-Over Brewing

In pour-over coffee, the filter isn’t a passive barrier—it actively shapes the flavor profile. Metal filters like Tiamo’s allow more oils and fine particles to pass through compared to paper, though cake-type paper filters (used with these) strike a balance by offering some clarity while still letting through body-enhancing compounds. The Tiamo K01 and K02 are optimized for these paper filters, with shapes and hole configurations that support a clean yet full-bodied cup.

Your pour speed directly impacts the result: slower pours extract more gently for brighter flavors, while faster pours increase extraction intensity. The Tiamo design enhances this effect by managing flow rate and avoiding channeling or uneven saturation.

Frequently Asked Questions

What’s the difference between the Tiamo K01 and K02 filters?

The K01 is designed for 1–2 people, with a top diameter of ~9.3 cm, height of ~6 cm, and base diameter of ~10 cm. The K02 is for 3–4 people, measuring ~11.3 cm in diameter, ~7 cm tall, and ~10.3 cm at the base. Both use cake-type paper filters, with the K01 for smaller brews and the K02 for larger volumes.

What materials are the Tiamo K01 and K02 made from?

The cup body is made from 304# stainless steel—a food-grade, corrosion-resistant material. The handle is made from 201# stainless steel. Both contribute to durability and heat resistance during brewing.

Do these filters require special paper?

Yes, they’re designed for use with cake-type (also called “cupcake” or “thick”) paper filters in the appropriate size—1–2 serving for K01, 3–4 servings for K02. These help balance clarity and body in the brewed coffee.

Does pour speed really change the flavor that much?

Yes. The Tiamo design enhances the impact of your pour. Slow, steady pouring extracts flavors more gently, leading to a lighter, brighter cup. Faster pouring increases extraction intensity, resulting in a richer, more robust brew.

What comes included with the Tiamo K01 and K02 filters?

Each filter set includes one stainless steel filter (either K01 or K02), one drip tray, and one 10g coffee powder scoop. No additional paper filters are included.
