Which is better, nanofiltration or reverse osmosis?

Reverse osmosis: it is a relatively fine membrane separation product at present. The filtration mode is reverse osmosis membrane, and the filtration accuracy reaches 0.000 1 micron, using electricity. It can filter out sediment, rust, colloid, organic matter, bacteria, viruses and heavy metals. The filtered water source has high purity and can be directly drunk, but it is expensive and will produce waste water. Suitable for all kinds of water quality.

Nanofiltration: between reverse osmosis and ultrafiltration. The filtration mode is nanofiltration membrane, the filtration accuracy reaches 0.00 1 micron, and electricity is also used. It can filter out sediment, rust, heavy metals and calcium and magnesium ions. It can filter out scale and retain some minerals, and the price is lower than that of reverse osmosis.

If your city is polluted by heavy industry, it is better to choose reverse osmosis water purifier. Angel's original long-acting reverse osmosis membrane has a filtration accuracy of 0.000 1 micron, which is one millionth of that of hair. Can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. In the water, thoroughly remove the alkali and scale in the water. If the water pollution is serious or unclear, it is recommended to buy an angel water purifier, and big brands are more secure.

Angel was selected as the brand of water purifier. Angel has been deeply involved in the field of water purification for 33 years, participated in the formulation of 14 national and industrial standards, has 768 patents, has a better understanding of the water quality in China, developed water purification products more suitable for China families, and developed a long-term reverse osmosis membrane, breaking the monopoly of foreign reverse osmosis membrane technology. Products sell well in 65 countries, such as the United States and Japan, and have won the choice of 200 million people around the world.
