This smart countertop purifier applies a 3-stage RO reverse osmosis filtration system that delivers high-quality filtration. It also doubles as a kettle, with 1-second instant heating and 1℃ temperature control. 24-hour UV sterilization inhibits 99.9% of bacterial growth and eliminates secondary pollution. An auto-fresh algorithm ensures the freshness of water while the self-cleaning program remotely monitors the filter status.
