Key Features
- [Dual Water Flow]: The T4-A RO system offers two purified water options: a standard RO-purified stream and a mineral-enhanced alkaline stream. Switch between them effortlessly based on your needs — both deliver contaminant-reduced drinking water. Dual LED indicators provide thorough sterilization, ensuring complete water safety from filtration to faucet.
- [10-Stage Filtration with RO Membrane]: This system reduces harmful substances, including PFOA & PFOS, chlorine, heavy metals, microbial, rust, colloids and more impurities, through its comprehensive filtration stages. The dedicated mineral-enriched line then infuses beneficial alkaline minerals, delivering healthier, great-tasting water.
- [450GPD Flow & 2:1 Pure to Drain]: With a 450-gallon-per-day capacity and industry-leading 2:1 water-saving ratio, the WD-T4-A provides fast, on-demand purified water while reducing wastewater by up to 800% compared to traditional RO systems.
- [Smart Filter Life Reminder]: You won’t miss a filter change with the indicator lights and buzzer alerts. Replacement intervals: CF filter: 6 months; RO membrane: 24 months; CB filter: 12 months; Alkaline mineralizer: 12 months.
- [Tankless Design]: The compact, tank-free system effectively avoids secondary contamination risks associated with water storage tanks, while freeing up 70% more under-sink space than traditional tank-based RO systems.
Warranty
[1-Year Warranty, Guaranteed Reliability]: We’ve got you covered with a full year of protection, so you can enjoy clean water worry-free.
