Cerafilter | Ceramic coffee filter that mellows the taste

The New Era of Coffee Filters: Ceramic Filters

Do you love coffee?

The time spent grinding your favorite beans, slowly drip brewing, and inhaling the spreading aroma is an irreplaceable and enriching experience, isn't it?

The "Cerafilter," a completely new coffee filter that brings an amazing change to your coffee time, is an item we highly recommend for those who enjoy the best cup of coffee with their favorite tools.

Bringing Happiness to People Through Arita Ware Technology

The creators of Cerafilter are THREE RIVERS, located in Arita Town, Saga Prefecture, known for Arita ware. They launched the brand "39arita" in gratitude to the pioneer potters of Arita ware, which has a history of over 400 years.

The number "39" not only signifies "thank you" but also incorporates the lucky number 39 from ancient Japan, carrying the wish that "infinite happiness reaches everyone who holds this product in their hands!"

Tiny, Invisible Holes That Smooth Out the Taste

Cerafilter is made from porous ceramic with countless tiny holes, each about 60 microns wide, like a strand of hair.

These holes allow the flavorful oils of the coffee beans, which are the umami components, to pass through while blocking out unpleasant flavors, thereby maximizing the coffee's taste and giving it a mellow finish.

Since typical paper or cloth filters cannot pass the bean oils, you can enjoy a new side of your familiar coffee.

Furthermore, the ceramic's far-infrared effect helps remove chlorine odors and impurities from water, which is a welcome feature. You can also use it as a water purifier by pouring tap water into it, or for green tea, black tea, and even shochu.

No More Traditional Paper or Cloth Filters – It's Eco-Friendly!

It's incredibly eco-friendly because it eliminates the need for disposable paper or cloth filters, which were essential for brewing coffee. You no longer need to stock up on filters.

Proper Care for a Long-Lasting Relationship

The Cerafilter requires a little more maintenance than disposable filters. However, with careful care, you can use it for a long time. 

〈Daily Care〉

① Discard grounds

It becomes difficult to remove coffee grounds once they dry, so discard them promptly.

② Rinse with water

Rinse thoroughly with water to ensure no grounds remain. No detergent is needed. Avoid using scrub brushes or metal brushes, as they can cause breakage or deterioration.

③ Boil in water

Pour hot water over it to remove coffee oils. Stop when the color disappears. Air dry before storing.

〈Special Care〉

If fine coffee grounds or impurities accumulate and clog the filter, you can completely restore it by baking it in a gas stove or oven.

Place a rack on a gas stove, put the Cerafilter on it, and bake over medium heat for about 15–20 minutes. Alternatively, bake in an oven for 15–30 minutes.

Turn off the heat, and once it has cooled sufficiently, wash with water or hot water.

A Clearly Noticeable Difference in Taste with Just One Sip

Our SiKiTO staff, who love coffee, actually brewed some coffee.

Although I love coffee, I was skeptical whether I could discern subtle taste differences... but the moment I took a sip, I was amazed by the change in mouthfeel!

I brewed it with a sweet and rich Mocha blend, and I found that the lingering bitterness I usually experience with paper drip coffee was gone, and the richness and umami were enhanced. This was an astonishing coffee experience.

If you give this as a gift to a coffee lover, they will surely be surprised.

Japan's Only Patented Ceramic Filter!

"Forming," a process that requires particularly delicate techniques in manufacturing, can only be done by artisans who have mastered Arita ware technology. The manufacturing method for Cerafilter is Japan's only patented ceramic filter.

Manufacturing Step ① Raw Materials

Three types of raw materials are blended to create the tiny holes that make coffee taste delicious.

Manufacturing Step ② Forming

Artisans meticulously hand-form each piece with delicate precision. Any mistake in this process can result in a failed product.

Manufacturing Step ③ Firing

Fired at 1,230℃ for 30 hours. High-temperature firing achieves the far-infrared effect, which makes beverages smoother and more delicious.

The Goal: "Everyone Can Be a Barista"

The vision of the Cerafilter, which enhances the flavor of your everyday coffee even without special skills or knowledge, is "that everyone in the world can become a barista."

Why not open up a new world of coffee for yourself?
