Abstract
Disclosed herein is a spiral wound type filter cartridge and more specifically, a spiral wound type filter cartridge in which activated carbon fiber is provided. The inside of spiral wound type filter cartridge is capable of serving as a carbon filter in a water purifier, thus eliminating the necessity of the use of any carbon filter for pre- or post-treatment in the process of purifying raw water, reducing an overall size of the water purifier and considerably reducing costs associated therewith.
