Waterdrop - WD-T4-A Alkaline pH+ Reverse Osmosis Water Filter, extra RTCF Filter - White

This Waterdrop T4-A Alkaline pH+ Reverse Osmosis System provides two convenient water options through its dual-flow faucet: standard RO-filtered water and mineral-enhanced alkaline water. Its 10-stage filtration process, including an RO membrane, helps reduce PFOA, PFOS, chlorine, heavy metals, rust, colloids, and other unwanted substances, while the alkaline line adds beneficial minerals for a refreshing taste. With a 450 GPD flow rate and a 2:1 pure-to-drain ratio, the system delivers filtered water quickly while helping reduce wastewater. The compact tankless design saves valuable under-sink space and minimizes water storage. Smart indicator lights and buzzer alerts remind users when filters need replacement. The system is NSF/ANSI 372 certified, made with BPA-free materials, and requires an electrical connection and countertop drilling for faucet installation.

The Waterdrop TSA under sink water filter system features 8-stage deep filtration with three filters to reduce PFAS, PFOA/PFOS, chlorine, fluoride, heavy metals, rust, and more, delivering cleaner, better-tasting water. Recommended by National Geographic, it has a compact, space-saving design with quick-connect fittings for easy DIY installation in 3 minutes and 3-second filter replacement. Built with durable, age-resistant materials, it passes rigorous pressure and durability tests to prevent leaks or cracks, while its upgraded filtration area minimizes clogging risks. With filter lifespans of up to 18 months, the TSA ensures long-lasting performance for municipal tap water, though it is not designed for well or hot water.

Featuring a 3:1 pure-to-drain ratio with drain water recycling and power-saving mode, it reduces waste and energy use. Its dual-cartridge filtration effectively reduces PFAS and other contaminants to deliver fresh, pure-tasting water, while filters offer long lifespans of 6 to 18 months for low maintenance. Compact at 17.1"L x 7"W x 15.6"H, it provides clean, convenient hydration without drilling or plumbing.
