A composition for purifying an ozone-containing gas comprising activated carbon, in which the percentage of the volume of pores having a pore diameter of 0.4-0.8 nm in the volume of pores having a pore diameter of 0.4-2.0 nm is 75% or more, and an ozone decomposition catalyst powder is disclosed. Also disclosed is a filter for purifying an ozone-containing exhaust gas comprising activated carbon powder, in which the percentage of the volume of pores having a pore diameter of 0.4-0.8 nm in the volume of pores having a pore diameter of 0.4-2.0 nm is 75% or more, and an ozone decomposition catalyst powder carried on a fiber supporting body. The composition and filter of the present invention can remarkably reduce the content of ozone and volatile organic compounds in ozone-containing exhaust gas from printers.

Purification composition and filter for ozone-containing exhaust gas

A method of cleaning air, including a humidifying operation for humidifying the air containing chemical contaminants by a humidifier and taking a part of the gaseous contaminants in the air into excessive moisture to remove the contaminants from the air, and a dehumidifying operation for dehumidifying the humidified air by a condenser and taking the gaseous chemical contaminants remaining, without being removed, in the humidifying operation into condensed water for removal. By using an oblique honeycomb having both front and rear faces and both upper and lower faces disposed in open state, air is led from the front opening part of the oblique honeycomb and water is fed from the upper opening part thereof to one or both of the humidifier and condenser.
