Design principle of Kono filter cup;

After absorbing water, the filter paper can be attached to the upper part of the filter cup where there is no skeleton, so as to reduce the air circulation space and control the contact time between water and powder. The convex groove skeleton at the bottom of Kono filter cup is the key design that can produce siphon effect in subsequent brewing.

This is the biggest difference in extraction principle between KONO and HARIO filter cups. The siphon design of Kono filter cup comes from a Japanese named Yasin Kono, so this filter cup is named after Kono.

HARIO's design:

The skeleton is designed to extend spirally from the bottom to the top. The skeleton is used to exhaust air, not to limit the exhaust air, whether it is stewing or brewing, but the spiral design extending to the top makes the water flow cause a certain torque to the coffee powder during the downward extraction.

Moreover, the spiral design can increase the residence time of certain hot water in the filter cup, thus improving the concentration and extraction rate. However, compared with Kono filter cup, HARIO filter cup is far less than Kono in concentration and extraction rate.
