FAQs & Information

Got questions? We have answers.

How does the FiltSipy straw work?

It uses a 0.01μm hollow fibre membrane that physically blocks microscopic contaminants, sediment, and heavy metals as water is drawn through the filter.

How long will one filter last me?

Each FiltSipy filter purifies up to 5,000 litres of water depending on source clarity, providing years of reliable hydration for outdoor adventures.

Can I attach it to bottles?

Yes, the dual screw-threaded design connects directly to standard 28mm plastic beverage bottles, squeeze bladders, and hydration packs.

Are chemicals used inside?

No chemicals, iodine, or batteries are used. FiltSipy uses purely mechanical hollow fibre ultrafiltration to keep your water completely natural, pure, and pleasant tasting.

How do I clean and store it?

Simply backwash the filter straw with clean water to flush out trapped sediment, then blow out remaining moisture and allow it to dry before long-term storage.

Is the plastic safe and BPA-free?

Absolutely. FiltSipy is manufactured entirely from premium food-grade, BPA-free ABS material built for rugged outdoor use.

Can it filter water from seawater?

No, it is designed specifically for freshwater sources like rivers, lakes, and streams. It does not remove dissolved salts from seawater.

Does it come with a satisfaction guarantee?

Yes, every purchase includes a 30-day money-back guarantee. If you are not completely satisfied with your FiltSipy straw, simply return it for a prompt and full refund.
