Coffee Phin Filter: Medium

✔ The standard volume of the filter is about 170ml. ✔ The number of errors on the filter and the disc filter must be equal and analyzed evenly. ✔ The size of the filter error must be compatible with the particle size of the ground coffee beans so that it can give about 55-60 coffee pearls/1 minute. ✔ The full lid must be tight to avoid heat loss. ✔ The error on the latch (lid) must also be analyzed evenly and have a thicker password than the password error on the body and disc filter to reduce coffee better.
