SimPure T1-100 RO System – Near 0 TDS, 100 GPD, 7-Stage, NSF/ANSI 58, Under-Sink

Compact, high-performance RO filtration for your kitchen

The SimPure T1-100 brings seven stages of reverse osmosis filtration into a compact under-sink package. With a built-in pump and a 2.5-gallon storage tank, it delivers purified water quickly, so you can enjoy a steady flow for everyday use, whether you’re filling a pitcher, a glass, or a pitcher for the fridge.

Certified against NSF/ANSI 58, this system targets a broad range of common contaminants. Expect noticeably crisper water as the filtration sequence reduces chlorine, certain heavy metals, PFAS-related compounds, and other substances that influence taste and odor. This isn’t about a single spec; it’s about clearer water across the board and a more refreshing finish from tap water.

Near-zero TDS, crisp flavor that adapts to your water

Using patent filtration technology, the T1-100 lowers dissolved solids toward near-zero levels (often below 25 ppm, depending on input water). In practice, you may notice a cleaner mouthfeel and a more balanced finish, with the system capable of achieving high removal rates for many streams.

Performance you can count on at home

• Flow: about 81 fluid ounces per minute, enabling swift access to purified water (roughly 1.3 gallons instantly).
• Storage: a 2.5-gallon tank helps sustain a ready supply for families or busy kitchens.
• Build and pump: a built-in pump supports steady water pressure for faucet and fridge connections.

DIY-friendly installation and maintenance

• Under-sink fit: all necessary parts are included for a straightforward setup without professional help.
• Easy cartridges: quick-change twist filters simplify replacement and upkeep.
• Long-term value: each cartridge set yields up to about 528 gallons of purified water, helping reduce plastic bottle usage.

Quality, support, and product choices

SimPure services customers from Seattle, WA, USA, since 2006, with trained water specialists available for questions over the product’s life. Note that the base T1-100 targets near-zero TDS for inputs under 200 ppm; for alkaline water, consider the T1-100ALK variant, with the caveat that TDS will not reach 0 ppm in that model.
