ABSTRACT:
A method of treating low-pressure untreated drinking water includes providing a low-pressure water filter device, running low-pressure untreated drinking water from a source of low-pressure untreated drinking water through a low-pressure water filter of the low-pressure water filter device, removing bacteria and viruses from the low pressure untreated drinking water at a level of Filter Bacteria Log Removal of greater than about 2 logs and a Filter Viruses Log Removal of greater than about 1 log, and filling a storage housing with treated drinking water at greater than about 5 mL/min. The low-pressure water filter device may include a connector for connecting to an untreated drinking water source, a low-pressure water filter comprising mesoporous activated carbon particles and a storage housing. The average fluid contact time with the low-pressure water filter may be greater than about 2 seconds.
