Water purifiers typically operate using multi-stage filtration technology. First, water passes through a pre-filter to remove large particles like sediment and suspended solids. An activated carbon filter then absorbs harmful substances such as chlorine, odors, and organic compounds. The reverse osmosis (RO) membrane performs precision filtration to eliminate microscopic contaminants including heavy metals, bacteria, and viruses, ensuring water purity. To guarantee purification effectiveness, LESSO water purifiers incorporate high-efficiency RO membranes combined with activated carbon, mineralization filters, and other advanced technologies to ensure safe and reliable water quality. The system automatically alerts users to replace filters when water quality standards aren't met, maintaining optimal purification performance. These technologies work synergistically to effectively enhance purification results and provide healthy, safe drinking water.
