T4-A is Designed for Healthy Living. Enjoy fresh, clean water that supports your healthiest life. Instantly turn your tap water into a refreshing, pure flow.
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.

How does the dual-flow feature benefit me?
You can switch instantly between standard RO-purified water for everyday drinking and an alkaline stream that adds beneficial minerals, perfect for coffee, tea, or anyone who prefers a smoother taste profile.
Does the system keep water hygienic after filtration?
Yes. Each water line has its own UV LED sterilizer that continuously disinfects the water as it leaves the filter, safeguarding freshness all the way to the faucet.
Does it require a storage tank?
No. The compact, tankless design prevents secondary contamination and frees up about 70 % more under-sink space compared with tank-based RO systems.
Is installation complicated?
No! The tank-free design make under-sink installation straightforward for most homeowners — no bulky tank to position or maintain.
Will the alkaline stream affect beverage flavor?
Yes — positively. The mineral-enhanced line can improve the taste and aroma of coffee, tea, and cooking water while still delivering contaminant-reduced purity.
