Outdoor Water Filter with 0.5 L Collapsible Bottle

Product description What water sources can I drink from? Suitable for clear freshwater from streams, lakes, springs or rainwater cisterns. Does the filter also remove viruses, salt or chemicals? No. The 0.1 µm hollow-fibre membrane filters out bacteria, particles and microplastics. Dissolved salts, many chemicals and viruses are not reliably removed. How do I use the water filter? Fill the bottle with water, screw the filter on tightly and drink directly through the mouthpiece. You may need to suck harder the first time you use it. Is the filter compatible with standard water bottles? Yes. The filter fits many standard bottles with a 28 mm thread. How long can the filter be used? It has a maximum capacity of 4,000 litres. Its actual lifespan depends on water quality, use and maintenance. Replace the filter if the flow rate becomes significantly lower.
