COMPLEX FILTER FOR WATER PURIFIER

摘要

A composite filter for water purification which simultaneously performs an adsorption function of various contaminants contained in water and a removal function of particles, improves bearing capacity of activated carbon or activated carbon fibers, and can easily confirm the exchange time thereof is provided. A composite filter for water purification comprises: a hollow core(20) installed in an inner part of the filter; a cylindrical first filter(30) which is closely adhered onto an outer surface of the core, and is formed from activated carbon(32) or activated carbon fibers; and a cylindrical second filter(40) which is closely adhered to an outer surface of the first filter, and is formed from non-woven fabric. The first filter is manufactured by forming activated carbon or activated carbon fibers into a cylindrical shape, and covering a cylindrical outer surface of the cylindrical shape with non-woven fabric(34).
