Water-Straw Description

Membrane Solutions® Water-Straw filters water quickly and easily. The product requires no batteries, and filters at least 1,500 liters of water over its lifetime.
Membrane Solutions® Water-Straw can be used to drink directly from surface waters, like a river or lake, or a container, like a bottle or a glass. It can even be connected to Membrane Solutions Gravity Bag for treating and storing bulk water. Its lightweight and slender design makes it perfect for hiking, traveling, and camping in areas where water may be unsafe to drink due to contamination by bacteria or parasites.
Membrane Solutions® Water-Straw uses advanced ultrafiltration membrane technology that removes up to 99.999999 percent of bacteria (e.g., Escherichia coli, Vibrio cholera, and Salmonella typhi) and 99.999 percent Of protozoan cysts (e.g., Cryptosporidium parvum, Giardia lamblia) that cause waterborne diseases.
Membrane Solutions® Water-Straw therefore greatly reduces the risk of contracting waterborne illnesses such as diarrhea, dysentery, and giardiasis.

Operating Instructions

  1. Backwash After Use.
    If the Water-Straw won't be used for an extended period of time, or if flow rate or taste quality has diminished then it is recommended to backflush. Backflushing is more effective if performed before letting the filter to dry out. First remove the dust cap, then twist off the mouthpiece and thread on a squeezable plastic water bottle (e.g., ones commonly available at grocery stores) containing clean and safe water to the threaded cap. Some bottles need to be connected to the bottle adapter first. Then with the bottle connected, invert the Water-Straw so that the intake is pointed downward. Gently squeeze the bottle so that water from the bottle flows slowly out of the straw intake. Backwashing is more effective if the pressure is pulsated. —500ml (170z) should be sufficient.

If the Water-Straw is going to be stored for an extended period of time then it is highly advisable to disassemble and let air dry for 1-2 days prior to storing. DO not store in sun or in areas with elevated temperatures. Recommended to store in a refrigerated environment (do not freeze if wet)

    Typical life is 1,500L of filtered water. However, if it is difficult to draw water through the Water-Straw, or if the flow rate has greatly diminished, then try backflushing. If water taste has deteriorated then backflush, allow to dry, and replace the GAC filter. If these steps don't improve performance, then the Water-Straw or the ultrafiltration module needs replacing.
