Paper texture of the Filter GC01 coffee filter

Small step, big difference

Pre-rinse for
a pure cup.

Rinse the filter with hot water before adding coffee. It removes any paper taste, pre-warms the dripper and your vessel, and ensures a clean, unobstructed water flow.

Pre-rinsing the coffee filter with hot water before brewing

How do you recognise good pour over filter paper?

Good pour over filter paper meets three criteria: it fits the dripper exactly, it lets water through at an even rate, and it adds no taste of its own to the coffee. Fit comes first. A filter that does not sit against the wall lets water run past the coffee bed, and that share never gets extracted. This is why the size matters more than the brand: a size 1 cone filter belongs in a dripper built for one to two cups, not in a larger one. Flow rate, together with grind size, decides how long water and coffee stay in contact, so a slower paper calls for a coarser grind. The Filter GC01 is made from wood pulp and comes 100 filters to a pack. It is a size 1 cone filter for one to two cups, its flow rate sits in the medium to slow range, and it is made in Japan.

Size 1 cone filters compared

All three papers carry the same size designation and therefore fit the same dripper. For the other brands the table lists only what follows from that designation itself.

The right coffee filter for a clean, sweet cup

A coffee filter is more than a consumable: it helps decide how clean, clear and balanced your coffee tastes in the end. The Filter GC01 is made from premium Japanese wood pulp and tuned to a medium-to-slow flow rate, for a controlled extraction that puts the sweetness of your coffee front and centre.

What makes a good coffee filter

These qualities make the GC01 a coffee filter you can rely on day after day:

Clean filtration: Premium Japanese wood pulp filters precisely and evenly.
Balanced extraction: The medium-to-slow flow rate highlights bright, sweet notes.
Perfect fit: A size 1 conical coffee filter, designed for the Graycano Dripper and compatible with the Hario V60 (size 01), among others.
Great value: 100 filters per pack last around 3 months of daily brewing.
Sustainable: Natural wood pulp, fully compostable, grounds and all, into the compost.

Coffee filter and Graycano: made for each other

The GC01 coffee filter reaches its full potential in the Graycano Dripper: even water distribution, precise extraction, a pure cup. And to keep your filters fanned out and always within reach, the Filterblock sits perfectly alongside.

Frequently asked questions

Unbleached paper can pass a faint papery taste into the first cups, while bleached paper is more neutral to begin with. The difference largely disappears once the filter is rinsed with hot water before brewing. Rinsing is worth doing with either version: it washes out loose fibres and warms the dripper and the server at the same time, so the brew water loses no temperature to cold metal. If you want to check the difference yourself, brew the same coffee once with and once without a rinse.

The extra cost sits in the manufacturing, not in the name. Specialty papers are cut more closely to a particular dripper shape, so the filter sits against the wall and no water runs past the coffee bed. On top of that comes a more consistent flow rate from pack to pack, and that is what makes a recipe repeatable. The clearest way to look at it is per cup: one pack of Filter GC01 holds 100 filters, so the difference spreads across 100 brews and barely registers next to the coffee itself.

The Filter GC01 are made from premium Japanese wood pulp paper. It is a slow-to-medium flow rate filter that lets every coffee particle speak for itself, highlighting bright, sweet notes in each brew.
