The following is a general description of water purifier products: 

Product type: according to the filtration principle and structure, water purifiers can be categorized into activated carbon filtration, ultrafiltration, reverse osmosis (RO), nanofiltration (NF) and ceramic filtration. 

Product Function: Purification function: effectively remove residual chlorine, odor, color and other chemical pollutants in water. 

Mineralization function: some water purifiers improve the taste and nutritional value of drinking water by adding minerals. 

Direct Drinking Function: Provide purified water that meets the direct drinking standard, which is convenient for users to drink directly. 

Intelligent control: Modern water purifiers are equipped with an intelligent display, which can show cartridge usage and water quality information. 

Water-saving design: adopts water-saving technology to reduce the amount of waste water in the water purification process. 

Product Specifications: Flow rate: depending on the model, the flow rate of the water purifier ranges from a few liters to tens of liters per minute. 

Filtration precision: according to the filtration technology, the filtration precision ranges from 0.01 micron to 0.0001 micron. 

Applicable scenes: home kitchen, office buildings, schools, hospitals, restaurants and so on. 

Safety information: Replace the cartridge regularly to avoid saturation of the cartridge affecting the purification effect. Follow the installation and operation guidelines in the product manual. Avoid use in extreme temperatures to ensure the normal operation of the equipment. 

Water purifiers need to meet a series of requirements and standards when exporting by sea, the following are the main requirements for exporting water purifiers by sea: 

1.Certification Requirements: North America: Water purifiers exported to North America need to meet local regulatory requirements, common certifications include NSF, UL, CSA, etc. CSA Group, as the world's leading standard-setting body, provides testing and certification services to ensure that the manufacturer's products comply with the relevant standards. 

2. Product test report: Export water purifiers need to provide product test reports to prove that they meet the safety and quality standards of the target market. 

3. Environmental management system certification: such as ISO 14001 certification, proving that the enterprise meets the requirements of environmental management in the production process. 

4. Quality management system certification: such as ISO 9001 certification, proving that the enterprise meets international standards in quality management. 

5. 3C certification: China's mandatory product certification, applicable to home appliances sold in China, proving that the product meets the safety requirements of China's national standards. 

6. National Food Quality Inspection Report: Certain markets may require a national food quality inspection report to prove that the water quality of the water purifier meets food-grade standards. 

7. Industrial products production license: to prove that the enterprise has the qualification and ability to produce the relevant products. 

8. Membrane Industry Association Certification: For water purifiers that use membrane technology, certification by the Membrane Industry Association may be required 250. 

9. Export Destination Distribution: China's exports of domestic water purifiers are relatively decentralized, mainly exported to the United States, Japan, India, Germany and South Korea and other countries.
