However, RO reverse osmosis water purifier water speed is relatively slow, and need to regularly replace the cartridge, the cost is higher.
2. Ultra-filtration: The filtration precision of ultra-filtration technology is 0.01 micron, which can effectively remove suspended solids, colloids, bacteria and other impurities in the water, but the removal of dissolved substances and heavy metals in the water is less effective. Ultra-filtration water purifier has a faster water output speed, and the filter cartridge has a relatively long life, and the cost is low. However, the water quality of ultrafiltration water purifier can not reach the standard of direct drinking, need to be used with other water purification equipment.
3. Nanofiltration membrane: nanofiltration membrane is a new membrane separation technology between reverse osmosis and ultrafiltration, with high efficiency separation performance and selective filtration capacity. It can effectively remove most of the heavy metals in the water, small molecules of organic matter, some hardness components and some dissolved salts, while retaining the beneficial minerals in the water. The filtration precision of nanofiltration membrane is usually between 0.001~0.002 micron, and the quality of water can meet the needs of domestic water, but also to a certain extent to meet the standard of healthy drinking water. However, the processing efficiency of nanofiltration membrane is slightly lower than that of reverse osmosis, and the removal of some dissolved substances is not as thorough as that of reverse osmosis, and regular cleaning and maintenance are required during operation to prevent membrane surface fouling and prolong service life.

Water quality requirements 
1. Local water quality: Before buying a water purifier, first of all, to understand the local water quality. If the local water quality is good, there are only some minor pollution problems, such as odor in the water, suspended solids, etc., you can choose ultra-filtration water purifier; if the local water quality is poor, there are heavy metal pollution and other issues, it is recommended to choose RO reverse osmosis water purifier.

Some consumers in the purchase of water purifiers, ignoring the life of the cartridge, resulting in the use of the process of frequent replacement of the cartridge, increasing the cost of use.
2. To choose a water purifier with a long filter life: When buying a water purifier, choose a water purifier with a long filter life. Generally speaking, the life of RO filter is 1-2 years, and the life of ultrafiltration filter is 2-3 years. Consumers can choose a water purifier with a long cartridge life according to their water consumption and water quality to reduce the cost of use.

Choosing a water purifier is an important decision that requires comprehensive consideration of several factors. During the purchasing process, it is important to avoid common misconceptions such as looking only at price and ignoring cartridge life to choose a water purifier that suits your needs.
