Air purification device, air purification filter, water purification device, and water purification cartridge

摘要

PROBLEM TO BE SOLVED: To provide a water purification device which can exhibit a water purification function sufficiently even when a filtration flow rate is high and in which such a problem is hardly caused that a porous carbon material leaks from a water purifier together with purified water.SOLUTION: The water purification device includes a column or a cartridge in which the porous carbon material is packed, which material has 1×10m/g or larger specific surface area when measured by a nitrogen BET method, 0.3 cm/g or higher pore volume when measured by the BJH method, and 75 μm or larger particle diameter. The bulk density of the porous carbon material is from 0.1 g/cmto 0.8 g/cm.SELECTED DRAWING: Figure 1
