Tiamo K-Type Pour-Over Filter Cup with Unbleached Cake Paper

If you've ever noticed muddled flavors or uneven extraction when brewing pour-over coffee, the filter paper—and the design of your filter cone—could be the culprit. Many standard filters alter extraction speed or add unwanted paper taste, affecting clarity and body. Choosing the right filter material and shape helps you brew cleaner, more balanced coffee every time.

The Tiamo K-type filter cup, paired with its dedicated unbleached cake filter papers, is engineered for 1–4 cup brewing sessions. These 50-count packs come in two sizes: K01 for 1–2 cups and K02 for 3–4 cups. Both are made from natural coniferous wood pulp and are completely unbleached, helping you achieve a cleaner-tasting cup without chemical residues or unwanted tastes.

What Is the Tiamo K-Type Filter Cup?

The Tiamo K-type filter cup is the newest pour-over design from the specialty coffee equipment brand CAFEDETIAMO. Its shape is distinctively K-style—a hybrid form that balances aspects of both wave (melitta-style) and cone (v60-like) designs. The cake-style filter it uses sits snugly inside, designed to regulate flow rate and encourage even saturation during your brew.

Why Unbleached Filter Paper Matters

Most coffee filters on the market are either bleached white (using chlorine or oxygen processes) or left in their natural brown state. The Tiamo K-type cake filters are neither dyed nor chemically treated—they’re made from natural coniferous tree pulp and are completely unbleached. This avoids introducing papery or chemical off-notes into your cup, a common issue with lower-grade bleached papers. Unbleached paper also tends to break down better in compost and is preferred by specialty brewers aiming for purity in flavor.

Filter Size and Pack Details

The set includes two types of filter paper:

• K01: 1–2 cup capacity (50 sheets), ideal for single or small batch brews
• K02: 3–4 cup capacity (50 sheets), better suited for sharing or larger sessions

Both filter sizes are optimized for use with the Tiamo K-type filter cup only. Each sheet is 50-count, meaning you get a total of 50 sheets per pack regardless of size option. The material is specified as paper pulp, unbleached, ensuring minimal impact on taste and maximum clarity in your brewed coffee.

How to Use the Tiamo K-Type Cup and Filters

To get the best results:

• Pre-wet the filter with hot water to remove any paper dust and preheat your brewer.
• Discard the rinse water before adding ground coffee.
• Use a medium-fine grind (comparable to table salt), aim for a 1:15 to 1:17 brew ratio, and pour in stages to control flow—just as you would with a V60 or Kalita Wave.

The K-type shape encourages even extraction by balancing flow rate and contact time. Avoid overfilling beyond the recommended brew sizes (1–2 or 3–4 cups) to maintain proper saturation and prevent overflow.

Frequently Asked Questions

Are Tiamo K-type filters really unbleached?

Yes, the Tiamo K01 and K02 cake filter papers are made from natural coniferous wood pulp and are completely unbleached. They contain no chlorine or oxygen bleach chemicals, ensuring no residual taste or chemical aroma affects your coffee’s flavor profile.

What’s the difference between the K01 and K02 filter paper sizes?

K01 is designed for 1–2 cup brews (50 sheets), while K02 is intended for 3–4 cups (also 50 sheets). The paper size and shape differ slightly to match the brew volume, ensuring proper flow and saturation for the intended number of cups.

Can I use Tiamo K-type filters in other pour-over cones?

No, these filters are specifically designed for the Tiamo K-type filter cup. Their shape, size, and folding are tailored to that cone and may not fit or function correctly in other pour-over devices like V60, Kalita Wave, or Melitta cones.

Is unbleached filter paper better for taste?

Many specialty brewers believe unbleached paper reduces unwanted paper flavors and avoids chemical residues, leading to a cleaner, more transparent cup. The lack of bleach also appeals to those prioritizing a more natural brewing process.

How many filters come in each pack?

Each pack—whether K01 or K02—contains 50 filter papers. K01 is for 1–2 cup brewing, and K02 is for 3–4 cups. That’s 50 sheets total per package, not per size option.
