The X3 RO water purifier is available in three models with capacities of 400, 500, and 600 GPD. It features two filters that deliver four-stage filtration, effectively removing sediment, rust, heavy metals, viruses, and bacteria from water. The compact design reduces overall size while maintaining high purification efficiency. This under-sink water purifier provides purified drinking water on demand, with no waiting time for filtration. Its ONE-PUSH filter structure makes filter replacement faster and more convenient. The system includes overwork protection and automatically stops pumping if continuous operation exceeds one hour. The X3 also comes with a lead-free faucet, helping prevent secondary contamination.
