Hollow NF Filter Core Life Test Hollow NF membrane made of imported medical-grade raw materials from Germany + cross-flow technology is the key of service life. Filter core life test:  150,000 times of dynamic pressure fatigue test result that the membrane element has no rupture, the water quality is good, the seal is good, and there is no water leakage, reaching 1.5 times the relevant test requirements of the National standard, and the filter core life is at least 10 years.

Hollow NF Membrane Water Purifier Features How Hollow NF Membrane Water Purifier Works 1, Permeate Selectively 2, Pure physical filtration by feed water pressure 3,Crossflow filtration, automatic washing and minimal fouling. The service life of hollow NF water purifier is more than 5 years. 4, Space-saving installation, easy to use, no waste water and no electricity required. Hollow NF Membrane Direct Drinking Water Features 1, Purer water contains desired mineral solutes: Ca, Mg, Fe, Zn, Sr, etc. 2, Remove viruses, bacteria, heavy metal, chemical residues, etc. 3, Water quality is weakly alkaline, small molecular clusters

How Hollow NF Membrane Water Purifier Works The surface of the hollow fiber NF membrane has pore size of 1-10nm, which can effectively filter pollutants harmful to the human body in tap water. The diameter of the smallest individual virus in water is 15-300nm, the diameter of bacteria is 200-800nm, the diameter of heavy metals (divalent and above compounds of mercury, lead, and cadmium in water) is more than 10nm, and the diameter of other large particles in the water is more than 500 nm (pesticide residues, organic matter, gel, rust, silt). Substances larger than 10 nm are naturally isolated and filtered through the principle of membrane pore size molecular sieve.

Can water go bad after a long time storing? Water ages quickly. Water molecules are distributed in a chain-like structure. If the water is not frequently hit by strong impacts, this chain-like structure will continue to expand and extend into aging water, commonly known as "dead water". If minors often drink aging water, they will Accelerate aging. In recent years, the incidence of esophageal cancer and gastric cancer has increased in many areas, and experts believe that it may be related to drinking water that has been stored for a long time.

Is the water dispenser okay? Xinhua News Agency, Beijing, February 22, 2006: Enterprise self-revealing industry insider: 1, more than 99% of household water dispensers are "toxic"; 2, water dispensers are the "power-consuming king" of household appliances Learn More More than 99% of household water dispensers are "toxic". (News Details ) Today Morning Express

Is bottled water good? The shelf life of bottled water is only 24 hours after opening the lid. After a few hours, bacteria reproduced under certain suitable temperature and environmental conditions, and the bottled water after three days basically turned into dead water containing new pollutants. Relevant departments have tested the bottled water that has been opened for drinking for two weeks, and the total number of bacteria has exceeded 12.5 times the upper limit of the bottled water factory standard.
