Have been done. In recent years, volatile chemical substances such as formalin generated from building materials and the like may affect resident's health, and it is also desired to remove such volatile substances. It is known that a conventional air purification device includes a filter made of a woven or nonwoven fabric that is finer than the unnecessary substances contained in the air. As a filter, a porous ceramic material or activated carbon has been used.

Or chemical action in which harmful unnecessary substances cause a chemical reaction to render them harmless. For example, activated carbon has a fine porous structure, so that it has an effect of trapping unnecessary substances in fine pores and chemically adsorbing an active surface with the unnecessary substances. Apart from such air purification, building materials such as tiles containing a material having a humidity control function such as diatomaceous earth have been proposed in order to appropriately maintain a humidity environment in an indoor space. Walls constructed with building materials that have a humidity control function absorb moisture when the humidity of the indoor space becomes excessively high, lowering the humidity of the indoor space, and release moisture when the indoor space is too dry to release the humidity of the indoor space. Raise. Thereby, the humidity of the indoor space is adjusted to an appropriate range. It is also known that a humidity control material such as diatomaceous earth has a deodorizing property and a gas adsorbing property, and it is said that the humidity control wall also has a function of deodorizing an indoor space and removing volatile chemical substances.

Was. For example, a simple mesh filter can remove relatively large dust and the like, but can hardly remove fine particles and volatile substances such as formalin described above. In addition, since clogging occurs with the passage of time, it is difficult to use continuously for a long period of time. Activated carbon can remove fine particles and odor, but its performance deteriorates in a relatively short period of time.
This is considered to be due to the clogging of the fine pores of the activated carbon that perform the function of removing unnecessary substances.

Since the air purifying member has the honeycomb structure, the chance of contact between the air purifying member and the air can be increased without increasing the passage resistance of the air. Although an original honeycomb has a hexagonal cross section in the through passage, a cross section such as a square, a rectangle, other polygons, a circle, an ellipse, and an oval can be adopted. Irregularities such as grooves and ridges are formed on the inner surface of the through passage, so that good contact with air can be achieved.

It can be juxtaposed at a density of 8 to 2500 pieces per corner area. The arrangement shape of these through passages and partition walls is as follows:
What is necessary is just to set so that an appropriate air purification function can be exhibited according to the amount of air passing through the air purification member, the flow velocity, and other environmental conditions. When the cross-sectional shape of the air purification member is determined, the number, cross-sectional area, and partition wall thickness of the passages arranged in the cross-sectional shape are set in correlation with each other. If the cross-sectional area of the through-path is reduced and the number is increased, the contact area with the air increases, so that unnecessary substances can be easily captured, but the ventilation resistance increases. Reducing the thickness of the partition increases the air passage area. As the ratio of the partition wall to the cross-sectional area increases, the amount of moisture and unnecessary substances that can be retained in the partition wall, that is, the air purification member, increases.

This makes it possible to remove excess moisture contained in the air and adjust the humidity of the air to an appropriate state. In addition, when the inorganic moisture conditioner absorbs water, it can also capture fine particles and volatile hydrophilic chemical substances dissolved in the water at the same time. Specifically, hydrophilic gases such as formalin and ammonia are effectively captured. When the air comes into contact with moisture present on the surface of the inorganic humidity conditioner, fine particles and chemical substances contained in the air can be easily taken into the moisture of the inorganic humidity conditioner. Since water-soluble or hydrophilic substances are well associated with water, not only the action of physically fitting into the porous structure of the inorganic humidifier, but also the action of moisture efficiently removes various chemical substances or fine particles. It will be trapped and removed from the air.

As a result, the surface of the inorganic humidity conditioner is prevented from being clogged with the trapped chemical substance or fine particles, and the surface of the inorganic humidity conditioner is always maintained in a state of good adsorbability or a good capturing function. In addition, chemical substances that have the property of dissolving in water or decomposing by water dissolve or decompose into the moisture absorbed by the inorganic humidity control material, thereby reducing the fineness of the inorganic humidity control material. This prevents the porous structure from being physically clogged with a solid material.

When the humidity of the passing air becomes low, the inorganic humidity conditioner contained in the water has the effect of releasing moisture retained in the inorganic humidity conditioner into the air and increasing the humidity. Thereby, the humidity of the air can be maintained in an appropriate range. Even if moisture evaporates from the inorganic humidifier and is released into the air, the particles and chemicals trapped with the moisture do not evaporate or are more difficult to volatilize than the moisture. Will not be released, or the amount released will be small. The adsorption state in chemical adsorption or physical adsorption differs depending on the type of the adsorbed gas or chemical substance.
