A water purifier filter and a water purifier comprising same, according to the present invention, comprises: a filter housing including an inlet and an outlet; a filter module which is provided inside the filter housing to purify the water having flowed in through the inlet and then supply same to the outlet, wherein the filter module comprises a first filter member formed as a hollow tube and a second filter member made of a material different from that of the first filter member.

A method of making activated carbon particles from hemp includes placing raw hemp within a predefined atmosphere to produce activated carbon particles from the raw hemp and carbonizing the raw hemp to produce the activated carbon particles. Hemp filters including the activated carbon particles from hemp are disclosed.

Methods of forming solid carbon products include disposing nanostructure carbon in a container, disposing the container in a press, compressing the nano structured carbon within the container, and fastening a lid to the container to form a filter. Further processing may include sintering the nanostructured carbon within the container and heating the nanostructured carbon within the container in an inert environment to form bonds between adjacent particles of nanostructured carbon. Other methods may include forming a plurality of compressed nanostructured carbon modules, placing the plurality of compressed nanostructured carbon modules within a container, and placing a lid on the container to form a filter structure. Related structures are also disclosed.

Embodiments relate to apparatus for manufacturing a carbon block filter and a method for manufacturing a carbon block filter. The apparatus for manufacturing a carbon block filter according to an embodiment may include a mold having an inner space, a heater coupled to the mold to heat the mold, a material injection unit injecting a material to the mold heated by the heater, a material pressing unit pressing the material, and a filter separation unit separating a thermally treated filter from the mold heated by the heater.

A replaceable air filter element has a multilayer filter medium panel configured for mounting on a reusable exoskeleton support frame. The exoskeleton support frame is installable on a flow face of the filter medium panel and is provided with U-shaped locking members configured to detachably engage with and mount the filter medium panel. The exoskeleton support frame is configured to be reused such that only the filter medium panel is replaced, thereby reducing the environmental waste and making for a “green” eco-friendly air filter element.

Provided is a water-purification cartridge to be replaceably accommodated in an accommodating portion of a water purifier. The cartridge includes activated carbon that removes impurities from water, forms, within the water purifier, a raw water flow path through which raw water flows downstream without passing through the activated carbon and a water purification flow path through which raw water flows downstream while passing through the activated carbon, and further includes a buffer portion that is disposed, within the water purifier, at a position upstream of flow path switching valves for selecting discharge from the raw water flow path or discharge from the water purification flow path and downstream of the activated carbon and that cuts off a water hammer propagating from the flow path switching valves to the activated carbon.

One aspect of the present invention relates to a carbonaceous material which has a benzene adsorption of 25 to 40% and a vitamin B12 adsorption of 13.0 to 50.0 mg/g, while having a pore volume of mesopores of 0.070 to 0.150 cm.sup.3/g as calculated from a nitrogen adsorption isotherm by means of a BJH method.
