Waterdrop T4-A 450 GPD Alkaline Dual-Flow Reverse Osmosis System
Price with Installation
$650.00
The Waterdrop T4-A 450 GPD Alkaline Dual-Flow Reverse Osmosis System combines advanced reverse osmosis filtration with alkaline remineralization, allowing you to choose between RO-purified water and mineral-enhanced alkaline drinking water from one convenient under-sink system.
With 10-stage filtration, 450 GPD production, a 2:1 pure-to-drain ratio, and a smart faucet, the T4-A delivers fast, efficient drinking water filtration while providing two distinct water options. The system is designed to reduce TDS, PFOA, PFOS, chlorine, fluoride, lead, Chromium-VI, heavy metals, bad taste and odor, and other impurities while the alkaline flow adds minerals back into the purified water.
Filtration Process
Advanced 10-Stage Filtration
The T4-A uses a 10-stage filtration process designed to reduce a wide range of common drinking water contaminants and impurities.
Dual-Flow Water Selection
Choose between RO-purified water or mineral-enhanced alkaline water from the same system, providing flexibility for different drinking and cooking preferences.
Alkaline Remineralization
The dedicated alkaline filtration stage adds minerals back into purified water for a mineral-enhanced taste and alkaline drinking water option.
High-Efficiency Reverse Osmosis
Produces up to 450 gallons per day with a 2:1 pure-to-drain ratio, helping reduce wastewater compared with many traditional reverse osmosis systems.
Smart Faucet & Dual LED Function
The smart faucet provides convenient access to both water options, while the dual LED function provides system-status information for each water line.
Warranty
1-Year Manufacturer Warranty
The Waterdrop T4-A is backed by a 1-year warranty covering manufacturing defects.
