FAQ
Frequently asked
questions
Everything you need to know about your FiltSipy Water Filter Straw. Need assistance?Contact Support
How does the 0.01μm hollow fiber membrane work?FiltSipy utilizes a microscopic 0.01-micron hollow fiber membrane that acts as a physical barrier. As water passes through, suspended sediment, dirt, and microscopic particulate matter are physically blocked while clean, fresh water passes through effortlessly without chemicals.
What kind of water sources can I filter?FiltSipy is designed for freshwater sources such as rivers, lakes, mountain creeks, streams, and rainwater. It should not be used with saltwater (ocean water), heavily chemical-polluted industrial runoff, or brackish water.
How long will each filter straw last?Each FiltSipy straw is rated for up to 5,000 liters of water filtration under normal freshwater conditions. Because this bundle is Buy 1 Get 1 Free, you receive two straws for up to 10,000 liters of total filtration capacity.
Does it fit standard disposable water bottles?Yes! FiltSipy features a dual-thread connector that screws directly onto standard 28mm threaded water bottles, soda bottles, and compatible squeeze bags, making it easy to create a squeeze filtration system on the go.
Do I need replacement filters or batteries?No batteries, electricity, or replacement cartridges are needed. FiltSipy operates entirely on manual suction or gravity/squeeze pressure, making it completely reliable in off-grid survival situations.
How do I clean and store the straw after use?After your hike, simply backwash the filter with clean tap water by blowing air or flushing water in reverse through the mouthpiece, then allow it to air-dry completely before storing in your pack.
How fast does shipping take?Orders ship quickly and typically arrive within 4-8 business days across the United States. You will receive tracking information via email as soon as your package ships.
