With M3 CARBON as the main raw material, we started basic research toward adopting carbon filters for water purification applications.
As anticipated, due to its particular shape, this substance allows water to pass through freely and does not clog easily. It also provides a high level of adsorption, is durable and its impact on the environment is minimal, allowing various materials to be absorbed.
Because it is lightweight and consists of fine particles that are easy to form, M3 CARBON allows the filter to be compact, thus facilitating distribution and inventory control. Rice husks, which provide the raw material, are abundant in Japan. In addition, all processes—from the initial forming to the finishing process—are carried out in Japan. Our product achieves a high level of Japanese quality by utilizing traditional manufacturing techniques.

In the midst of increased concern about the environment, the concept of carbon neutrality is attracting a great deal of attention. Use of vegetable based raw materials allows the carbon balance to be maintained. In addition, reducing the CO2 emitted during the manufacturing and distribution process achieves neutrality with respect to the environment, thereby contributing to environmental conservation.
By reusing surplus rice husks, i.e. vegetation based natural resources, transport is reduced to the short distances between locations within Japan. This not only represents ecology that conforms to the concept of carbon neutrality, it also represents economy since—at the same time—costs are reduced.

The amazing properties of M3 CARBON

2 to 50 nm “meso-pores”
give excellent adsorption

Coconut shell activated carbon M3 CARBON

Countless micro-pores less than 2nm, meso-pores ranging from 2 to 50 nm and macro-pores less than 50nm exist on the surface of M3 CARBON.
It is meso-pores that are considered to have the best adsorption properties.
Compared to coconut shell activated carbon, which consists mainly of micro-pores and macro-pores, M3 CARBON provides a good balance of the three pore types, with meso-pores acting as the most important element.

Comparison between M3 CARBON and

Compared to the chunky form of coconut shell activated carbon, the thin, flat form of M3 CARBON pieces provides the ideal aspect ratio (ratio between the length of the long and short sides) for filters. Because of the low resistance that they present to the passage of water, these dimensions allow the water to flow through smoothly. In addition, little damage is caused by the pressure of water flow, and since the amount of clogging is small, the filter allows the passage of large quantities of water and has good durability.

The surface area of M3 CARBON is
1.5 times that of coconut shell
activated carbon

Careful measurement of M3 CARBON grains and those of coconut shell activated carbon shows a significant difference in their respective surface areas. This difference results from the shape of the M3 CARBON grains, and from the presence of small indentations on the surface the M3 CARBON. In addition, M3 CARBON has a better total surface area / total volume ratio than coconut shell activated carbon. This means that M3 CARBON has a larger area of contact with the running water, allowing it to quickly adsorb particles of various types.
