Features:Ultra High Precision: 0.0001 micron ultra-high filtration precision, effective filtration of organic matter, metal ions and other soluble substances, the removal rate is as high as 99.9%.Multiple Filtration: the RO membrane (reverse osmosis membrane) and UF membrane (hollow fiber ultrafiltration membrane) are used in this water filter. Through multiple filtration, water molecules can pass through, while inorganic salts, heavy metal ions, organic matters, colloids, bacteria and other magazines in the water can not pass through the RO membrane, so as to achieve the purpose of filtration.Super Water Purification Capacity: this water filter can filter at least 8000 liters of water, equivalent to 16000 bottles of 500ml water, 300 MLper20 pumping,reduce TDS, and produce purified water. The filter element can be cleaned or replaced.Ergonomic Design: the handle is provided with a number of grooves to increase the friction between the palm and the handle, which can support the whole palm to the thumb, providing the best touch and making the user's use process easy and comfortable.This water filter will help you when you go hiking, camping, traveling, taking risks and encountering disasters.Product :1, Product features:Package weight: 528g1. Provide convenient, safe and clean outdoor drinking water2. Super water purification capacity: under normal conditions, it can filter at least 8000 liters of water to remove heavy metals, reduce TDS and remove all salts. Produce pure water3. No chemicals4. No power / battery or replacement parts are required2, Average flow rate:Under the condition of reverse osmosis filtration, the flow rate of hand pump is 250-300ml in 1 minuteUnder the condition of ultrafiltration by hand pump, the flow rate is more than 1.5L per minute.3, Put the pump into the water supply pipe according to the manual. Take out the sand head from the source water after use. Pump out the residual source water. After washing with pure water, pump out all the water and shake it dry. Wrap the pipeline and put it into a plastic bag.matters needing attention:1. Please do not use the front 100-200ml water made by the system. After the filter element is washed, 30-50ML can be washed before the second use2. Filter water, try not to collect heavy salt water and chemical pollution water. It is easy to cause pollution and blockage of filter element and reduce service life.3. Keep in a cool and dry place.4. Please pay attention to the direction of water flow arrow and pump at constant speed.Product packaging:1 x water filter1 x water bag1 x silicone hose1 x sand head1 x storage bag1 x user manual
