Patent ID: 7615152

Claim:
A water filter device for treating untreated drinking water, said water filter device comprising: (a) a connector for providing fluid communication between said water filter device and an untreated drinking water source; (b) a low-pressure water filter in fluid communication with said connector, said low-pressure water filter for treating untreated drinking water, said water filter comprising a water filter material, said water filter material comprising filter particles consisting of mesoporous activated carbon, and said water filter having a Filter Bacteria Log Removal of greater than about 2 logs, wherein: (i) the sum of the mesopore and macropore volumes of said filter particles is between about 0.2 mL/g and about 2 mL/g; wherein mesopore means an intra-particle pore having a diameter between 2 nm and 50 nm, and macropore means an intra-particle pore having a diameter greater than 50 nm; (ii) the total pore volume of said filter particles is greater than about 0.4 mL/g and less than about 3 ml/g; and (iii) the ratio of the sum of mesopore and macropore volumes to the total pore volume of said filter particles is greater than about 0.3; (c) a storage housing in fluid communication with said low-pressure water filter, said storage housing for storing treated drinking water treated by said water filter; (d) an automatic shutoff valve in fluid communication with said storage housing, said automatic shutoff valve for arresting the flow of treated drinking water into said storage housing; and (e) a dispenser in fluid communication with said storage housing, said dispenser for dispensing treated drinking water from said storage housing; wherein the treated drinking enters into said storage housing at the rate of at least about 5 mL/min but not greater than about 2,000 mL/min until activating said automatic shutoff valve, such that the flow of treated drinking water into said storage housing is arrested, wherein said water filter device is a non-electric water filter device, and wherein said water filter device is operable to remove microorganisms from said untreated drinking water flowing into said connector and out of said low-pressure water filter.
