Gravity water purification bags can be used as safe drinking water guarantee equipment for emergency rescue, military equipment, outdoor operations, tourism, exploration, mountaineering, hiking, and natural disasters such as earthquakes and floods.
Gravity water purification bags can purify natural water without industrial pollution such as river water, rainwater, lake water, stream water, etc. [1] into direct drinking water, which can be drunk without boiling.
Gravity water purification bags use double-control membrane ceramic filter elements, which can remove 99.9999% of pathogenic bacteria [2] and other suspended pollutants in water. Its double-layer ceramic membrane structure can ensure that the membrane layer will not be damaged during the cleaning process, effectively ensuring the stability of the filter element during the entire use process. NMC™ filter material can effectively reduce the concentration of harmful ions (such as lead, cadmium, chromium, arsenic, etc.) in water, effectively inhibit bacteria during use, and make the water safer and healthier.
[1] Class III and above surface water or groundwater.
[2] Escherichia coli, Staphylococcus aureus, Salmonella typhi, Cholera, Legionella, Pseudomonas aeruginosa, etc.
