Cloth, paper, and metal filters

Filter Material Comparisons

• Cloth Filters:

• Allow some oils through while retaining most fines.

• Produce a clean but full-bodied cup.

• Reusable but require thorough cleaning to avoid rancid flavors.

• Common in traditional Japanese siphon brewing.

• Paper Filters:

• Trap oils and fine particles effectively.

• Yield a bright, clean, and high-clarity cup.

• Single-use, available bleached (cleaner taste) or unbleached (may impart papery notes if not rinsed).

• Standard in V60, Chemex, Kalita, and Melitta.

• Metal Filters:

• Stainless steel or mesh designs allow oils and fines into the cup.

• Produce heavier body and richer mouthfeel.

• Reusable and durable, but harder to clean thoroughly.

• Used in French press, AeroPress metal disks, and some pour-over devices.

Practical Considerations

• Flavor: Paper → clarity; Metal → body; Cloth → balance.
• Maintenance: Paper → disposable; Cloth → high cleaning demand; Metal → reusable but prone to buildup.
• Environmental Impact: Cloth and metal are sustainable options; paper creates waste but offers convenience.

Summary

Filter material choice significantly affects coffee’s clarity, body, and flavor expression. Paper emphasizes brightness, metal emphasizes richness, and cloth offers a middle ground—making filter selection a key variable in brewing design.
