The LPRO-JS1-1500 reverse osmosis pure water machine adopts advanced single-stage low-pressure reverse osmosis technology to purify tap water. Combined with carefully designed filtration and adsorption systems, it can effectively remove various harmful substances such as bacteria, residues, heavy metal ions, etc. in water, and can also remove carcinogenic and pathogenic substances such as chloroform and fluoride that cannot be removed by conventional methods. The conductivity of tap water in the vast majority of regions in China is ≤ 500us/cm. Therefore, when using this mechanism for water production, it is important to pay attention to the quality of the raw water and strictly follow the instructions for operation, maintenance, and upkeep. The conductivity of the purified water produced can be fully maintained at the national standard of 10? Ensure the production of pure water for direct drinking below s/cm, in accordance with the hygiene requirements of Annex 4 of the Health Supervision and Administration Commission (1998) No. 19 document and the Ministry of Health GB5749-2006 "Sanitary Standards for Drinking Water".
