The wrong shape won't fit your dripper. The wrong size affects flow and extraction. Bleached vs unbleached is a question that comes up repeatedly. This guide covers everything you need to know to buy the right filters confidently. - Cone (V60) vs trapezoid (Kalita/Melitta) filter shapes - Hario and Kalita filter size reference - Bleached white vs unbleached brown — does it matter? - Pre-rinsing: why and how ## Filter Shapes: Cone vs Trapezoid There are two fundamental filter shapes: **Cone (conical):** - Used in Hario V60, ORIGAMI (with cone adapter) - Comes to a point at the bottom - Designed for single-hole cone drippers **Trapezoid (fan-shaped):** - Used in Kalita flat-bed drippers, Melitta single-hole drippers - Flat bottom with two side seams - **Not compatible with cone drippers** These shapes are not interchangeable. Always confirm your dripper type before buying filters. ## Hario V60 Filters > **HARIO V60 Paper Coffee Filters 02W White for 1-4 Cups 100 Pack VCF-02-100W** / 価格: ¥407 / 評価: 4.6 / 特徴: 100-sheet pack / Size 02 (1–4 cups) / Made in Japan → [Amazonで商品を見る](https://www.amazon.co.jp/dp/B001U7EOYA?tag=ps0036fr-22 ) ※アフィリエイトリンク | Size | Cups | Product code | |------|------|-------------| | 01 | 1–2 cups | VCF-01-100W | | 02 | 1–4 cups | VCF-02-100W | The V60 02 is the most widely used size — it works with the standard V60 02 dripper. Hario's own filters are Made in Japan with consistent quality and minimal paper smell. They are the recommended first choice for V60 users. ## Kalita Trapezoid Filters > **Kalita Coffee Paper Filter Trapezoid 1-2 Persons FP101 White 100 Sheets** / 価格: ¥363 / 評価: 4.5 / 特徴: 100-sheet pack / Trapezoid size 101 (1–2 cups) / FP101 → [Amazonで商品を見る](https://www.amazon.co.jp/dp/B003AKXGO4?tag=ps0036fr-22 ) ※アフィリエイトリンク | Size | Persons | Most common use | |------|---------|----------------| | 101 | 1–2 | Small home dripper | | 102 | 2–4 | Standard home dripper | | 103 | 4–7 | Large/office brewing | Kalita's 102 is the most common household size. The number system corresponds to the dripper model number — a Kalita 101 dripper uses 101 filters; a 102 dripper uses 102 filters. ## Bleached White vs Unbleached Brown | | White (bleached) | Brown (unbleached) | |--|-----------------|-------------------| | Bleaching | Oxygen or chlorine | None | | Flavor impact | Negligible | Negligible | | Paper smell | Minimal | Slightly more | | Environmental note | Oxygen bleaching is low-impact | No bleaching chemicals | **The practical answer: bleached vs unbleached makes negligible difference to flavor** — especially if you pre-rinse your filter (which you should). Choose based on preference: - Brown if you prefer no chemical processing - White if you prefer cleaner appearance or easier visual color assessment Before adding coffee, place the filter in the dripper and pour hot water through it to saturate the paper. Pour out the rinse water. This eliminates residual paper smell and pre-heats your dripper and server. It takes 10 seconds and meaningfully improves the clarity of the cup — especially noticeable with lighter roast specialty coffee. ## Dripper-to-Filter Compatibility Reference | Dripper | Filter shape | Recommended filter | |---------|--------------|--------------------| | Hario V60 01 | Cone | VCF-01 (Hario) | | Hario V60 02 | Cone | VCF-02 (Hario) | | Kalita 101 | Trapezoid | 101 filter (Kalita) | | Kalita 102 | Trapezoid | 102 filter (Kalita) | | Melitta 1×1 | Trapezoid | 1×1 filter (Melitta) | | Kalita Wave 155 | Wave | KWF-155 (Kalita) | | Kalita Wave 185 | Wave | KWF-185 (Kalita) | Note: Kalita Wave filters are a third shape category — corrugated paper that does not match standard trapezoid or cone filters. ## Storage Store paper filters in a dry location. Moisture absorption accelerates paper smell. After opening, keep filters in a sealed bag or tin. Even small amounts of humidity can affect filter quality over time. **Pros** - Paper filtration removes coffee oils and fines for a clean, clear cup - Disposable design requires no cleaning — simplest maintenance of any filter type - Low per-filter cost makes ongoing expense minimal **Cons** - Filter shape and size must precisely match the dripper — incompatible filters are unusable - Ongoing paper waste (metal filters are the alternative) - Moisture storage required to prevent paper smell buildup ## Final Verdict Filter selection comes down to one rule: **match the filter shape and size exactly to your dripper**. Hario V60 02 uses VCF-02 cone filters. Kalita 102 drippers use 102 trapezoid filters. Wave drippers use Wave filters. Beyond that, bleached vs unbleached is a preference call with no practical flavor consequence. Pre-rinsing costs 10 seconds and improves every cup. ## Related Articles - [Best Electric Coffee Grinders Under 20000 Yen: 7 Picks for Serious Home Brewers](https://coffee-guide.jp/gear/coffee-grinder-under-20000-yen-recommended) - [Dripper Comparison: V60 vs Kalita Wave vs Chemex vs ORIGAMI [2026]](https://coffee-guide.jp/gear/dripper-comparison-v60-kalita-chemex-origami) - [Glass Coffee Dripper Guide — HARIO V60 Glass and Material Comparison](https://coffee-guide.jp/gear/glass-coffee-dripper-recommended) - [HARIO Coffee Gear Guide — V60 Drippers, Servers, and Kettles](https://coffee-guide.jp/gear/hario-brand-coffee-gear-guide) - [Hario Switch Immersion Dripper Review — One Dripper, Two Brewing Styles](https://coffee-guide.jp/gear/hario-switch-immersion-dripper-review) ## Frequently Asked Questions **Q: Hario vs Kalita paper filter — which is better?** A: The most important thing is to match the filter to your dripper brand. Use Hario filters for the V60 and Kalita filters for the Kalita Wave. **Q: Bleached or unbleached paper filter — which should I choose?** A: Both have minimal impact on flavor when properly rinsed. Unbleached (brown) filters have a lower environmental footprint. Always rinse with hot water before use. **Q: Can I use a metal filter instead of a paper filter?** A: Yes, but coffee oils pass through, changing the flavor profile — you get a richer, heavier body similar to French press rather than the clean cup from paper. --- *This is the markdown version for AI crawlers.
