SimPure T1-400UV Tankless RO System — 400 GPD, UV, Near 0 TDS, NSF/ANSI 58 Certified

Pure water reimagined for the modern kitchen

The SimPure T1-400UV is a compact, tankless under-sink RO system designed to fit beneath most sinks. With built-in UV purification and an efficient design, it delivers high-quality water without sacrificing cabinet space. Backed by SGS certification to the NSF/ANSI 58 standard, this unit has been tested for performance and reliability.

Powered by an eight-stage filtration process, it targets more than 1,000 contaminants, including fluoride, nitrates/nitrites, PFAS/PFOA/PFOS, heavy metals, chloride, and more. Expect water with dramatically reduced dissolved solids, helping you enjoy a crisper taste profile and clearer appearance in your drinking water.

How it performs in daily use

Designed for real-world use, the T1-400UV offers water near 0 TDS by leveraging advanced RO technology. In practical terms, it reduces initial tap water TDS levels substantially, achieving a high removal rate while preserving essential minerals through its multi-stage sequence. A pure-to-drain ratio of 1.5:1 helps minimize wastewater compared with many traditional systems.

The built-in UV light adds an extra layer of assurance for taste and odor while the tankless design ensures fresh water on demand and easier cleaning. With a production capacity up to 400 gallons per day, you can stock up during busy mornings and still have purified water during dinner prep.

Design, maintenance, and support you can count on

The system is BPA-free and ships with quick-change twist cartridges, simplifying routine maintenance. SimPure has served customers in the USA since 2006, based in Seattle, and offers ongoing support from a team of water specialists. If you need replacement filters, you’ll find options readily available.

• Note: If you seek very low TDS, the T1-400UV is optimized for tap water with <200 ppm TDS. For naturally alkaline water, consider the T1-400ALK variant.
• Included features: built-in pump, compact footprint, and NSF/ANSI 58 certification underline a commitment to quality.
