Air-cleaning filter, method of producing the same, and high-level cleaning device

An air filter comprising:

• a supporter, a first inorganic material layer formed of powder of fraipontite mineral and powder of an inorganic substance as a binder, and a second inorganic material layer formed of powder of an inorganic substance, wherein one of the first inorganic material layer and the second inorganic material layer is fixed to the surface of the supporter, and the other of the first inorganic material layer and the second inorganic material layer is fixed to the surface of the one inorganic material layer.

An air filter comprising:

• a supporter and a layer formed of a plurality of pellets fixed to the surface of the supporter, wherein the pellet is formed by pelletizing a mixture of powder of fraipontite mineral and powder of an inorganic substance as a binder.

An air filter comprising:

• a supporter and a layer formed of a plurality of pellets fixed to the surface of the supporter, wherein the pellet is formed by pelletizing a mixture of powder of fraipontite mineral and powder of an inorganic substance as a binder and is then coated with powder of an inorganic substance, or the pellet is formed by pelletizing powder of an inorganic substance and is then coated with powder of fraipontite mineral, using powder of an inorganic substance as a binder.

An air filter comprising:

• a casing filled with a plurality of pellets, wherein the pellet is formed by pelletizing powder of fraipontite mineral, using powder of an inorganic substance as a binder, or the pellet is formed by pelletizing powder of fraipontite mineral, using powder of an inorganic substance as a binder and is then coated with powder of an inorganic substance, or the pellet is formed by pelletizing powder of an inorganic substance and is then coated with powder of fraipontite mineral, using powder of an inorganic substance as a binder.

An air filter comprising:

• a supporter and an inorganic material layer that is formed by fixing a mixture to the surface of the supporter, using an inorganic substance as a binder, the mixture comprising powder of fraipontite mineral and one or both of powder of manganese oxide and permanganate.

A method for manufacturing an air filter comprising the steps of:

• immersing a supporter in a suspension in which powder of fraipontite mineral and powder of an inorganic substance as a binder are dispersed as the suspensoid, and
• drying the supporter impregnated with the suspensoid, thereby forming an inorganic material layer fixed to the surface of the supporter.
