A method of filtering water contained in a squeezable bottle includes filling the squeezable water bottle with water; screwing a portable filtration apparatus onto the squeezable water bottle, the portable filtration apparatus includes a cap piece, the cap piece having a mouthpiece and a threaded portion, wherein the threaded portion is configured to screw onto the squeezable bottle; and a filter fluidly connected to the cap piece, wherein the filter comprises a plurality of hydrophilic hollow fibers and hydrophobic hollow fibers, the hydrophobic fibers are configured to allow air to flow into the squeezable bottle; flowing a filtrate out through the mouthpiece from the filter in response to a pressure differential between an inside portion of the squeezable bottle and an outside portion of the squeezable bottle.
A portable water filtration apparatus for a squeezable bottle, the portable water filtration apparatus comprising:
A method of filtering water contained in a squeezable bottle, comprising:
The method claim of 8, wherein the pressure differential occurs in response to squeezing an outside portion of the squeezable bottle.
The method claim of 8, wherein the pressure differential occurs in response to applying suction at the mouthpiece.
The method claim of 8, wherein the filter is configured to at least produce a turbidity reduction in a water sample from an initial turbidity of 40 Nephelometric Turbidity Unit (NTU) to a final turbidity of less than 1 NTU, under conditions described in the World Health Organization's (WHO) Standard International Scheme to Evaluate Household Water Treatment Technologies Filtration Batch System Technology V 2.0 (Geneva, 2016), wherein the initial turbidity is obtained through an addition of fine test dust (ISO spec. 12103-A2) to reverse osmosis treated water.
The method claim of 8, wherein the filter is configured to continuously flow at least 6,000 liters of reverse osmosis treated water having less than 1 NTU.
The method claim of 8, wherein the filter is configured to achieve a percent reduction of bacteria of at least 99%, under conditions described in the World Health Organization's (WHO) Standard International Scheme to Evaluate Household Water Treatment Technologies Filtration Batch System Technology V 2.0 (Geneva, 2016).
