Chemex, Hario, Tiamo: Filter Paper Comparison for Pour-Over
Ever wondered why your Chemex pour-over takes forever to draw down, or why your coffee sometimes tastes oddly papery? The answer isn’t just your grind or pour technique—it might be the filter paper. With different brands offering varied flow rates, thicknesses, and even subtle flavors, choosing the right paper can make or break your pour-over experience.
If you're comparing Chemex, Hario, and Tiamo filter papers, here’s the quick takeaway: Chemex papers are the most expensive at around $1.70–$1.90 per sheet, but reusable up to 3 times (bringing cost down to ~$0.56–$0.60); Hario’s V-01 is mid-range at ~$0.35, with moderate flow and noticeable paper taste; Tiamo’s version is cheapest at ~$0.27, but inconsistent and thin.
Why Filter Paper Matters in Pour-Over Coffee
Filter paper isn’t just a barrier—it affects brew time, flavor clarity, and even how your coffee tastes. A slower-drawing filter might over-extract, while a fast one could under-extract. The material, thickness, and porosity all influence how water passes through your coffee bed. That’s why the brand and type of paper you use matters just as much as your grind size or water temperature.
Chemex vs. Hario vs. Tiamo: Filter Paper Face-Off
To understand how these three popular filter types compare, we tested 17g doses with 300ml water, using a standard 20-second bloom. Here’s what we found, measured in real-world brewing conditions:
| Brand & Model | Price per Sheet | Flow Rate (300ml Drawdown Time) | Paper Taste (During Bloom) | Other Notes |
|---|---|---|---|---|
| Chemex (1–3 cup, curved filter) | ~$1.70–$1.90 (reusable down to ~$0.56–$0.60 after 3 uses) | ~2:50 | Almost none | Highly porous, tall cone shape increases brew time; washable and reusable; ships internationally at high cost |
| Hario V-01 | ~$0.35 | ~3:10 | Noticeable wood pulp taste | Medium flow; standard for Hario V60 users |
| Tiamo V-01 | ~$0.27 | ~3:35 | Mild paper taste | Inconsistent performance; thin paper, poor cup fit |
Note: Tiamo’s filter performance varies batch to batch—some are fast, others very slow—making it the least predictable option. Price is its only clear advantage.
Flow Rate, Reusability, and Flavor: What Sets Them Apart
The Chemex filter’s unique curved, tall design results in a narrower coffee bed compared to the wider cones of Hario and Tiamo. This means water interacts with coffee grounds for longer, slowing extraction. In our tests, Chemex filters drew down in just under three minutes, while Hario took about 3:10 and Tiamo a full 3:35.
Chemex filters also demonstrated almost no paper taste, even during the bloom phase. Hario’s V-01 had a distinct woody pulp flavor, while Tiamo’s was milder but still present. Tiamo’s paper is thinner and doesn’t seal as well against the brewer, potentially causing uneven flow.
On reusability, Chemex stands out: with proper rinsing and drying, the same filter can be used up to three times without significant impact on taste or performance. In extended testing over seven hours, no residual coffee flavor was detected after a simple rinse and air dry.
Frequently Asked Questions
Which filter paper gives the cleanest taste?
Chemex filters produce the cleanest-tasting coffee, with almost no paper flavor detected during brewing. Their thick, oxygen-bleached paper minimizes any papery taste, making them ideal for highlighting bright, nuanced coffees.
Are Chemex filters really worth the higher price?
Chemex filters cost more upfront (~$1.70–$1.90 each), but they can be reused up to three times with proper care, lowering the cost to around $0.56–$0.60 per use. Even factoring in import fees, they’re cost-effective for dedicated Chemex users.
Do Hario V-01 filters affect coffee flavor?
Yes, Hario V-01 filters have a noticeable wood pulp taste, especially during the bloom. While not overwhelming, it’s more pronounced than Chemex or Tiamo filters, which are milder or nearly neutral.
Why are Tiamo filters so inconsistent?
Tiamo V-01 filters vary significantly in flow rate and performance—some draw down quickly, others very slowly. They’re also thin and don’t always seal well against the brewer, leading to unreliable extractions. Their low price is their main advantage.
Can you reuse pour-over filter papers?
Yes, Chemex filters can be reused 2–3 times if rinsed thoroughly after each use and allowed to dry completely. Reusing them doesn’t strongly affect extraction quality or introduce off-flavors when cared for properly.
