It features an advanced 8-stage filtration process designed to restore the water's natural alkalinity and mineral balance, effectively removing 99.99% of over 1,000 contaminants, including, PFAS (PFOA/PFOS), heavy metals (Lead, Arsenic and etc), TDS, chlorine, fluoride, and microplastics (See SGS Test Report for more details).
Great Tasting Water: Purified pH+ Alkaline RO System
SimPure T1-400 Alkaline Reverse Osmosis System sets itself apart from standard RO systems by addressing a common issue—slightly acidic water caused by mineral loss. Its 7th-stage Alkaline Remineralization filter restores essential minerals like calcium, magnesium, and potassium, delivering naturally balanced, great-tasting water with a pH >7.5.
Compact Tankless Alkaline RO System: Instant Water, Space-Saving Under Sink
SimPure T1-400 Tankless Under Sink Alkaline Reverse Osmosis system increases under-sink filtration efficiency by 70%. Its tank-free design delivers water instantly while preventing issues associated with traditional storage tanks. Unlike conventional units that take hours to fill, the T1-400 provides filtered water on demand for everyday use.
400 GPD High Flow Alkaline Water System: 1.5:1 Pure-to-Drain Ratio
SimPure T1-400 Alkaline Tankless 8-Stage RO System with Remineralization includes a boost pump for faster water delivery, producing 400 GPD (0.28 gallons/s) and filling a cup in just 12 seconds. Compared to standard RO systems, it offers an efficient 1.5:1 output-to-waste ratio, generating only 1 gallon of wastewater for every 1.5 gallons of filtered water, helping reduce plastic usage and saving on bottled water costs.
Alkaline Water Filter Changes: 3-Second Twist-in Filter Design & Timely Filter Replacement Alerts
This under-sink alkaline water filter system features a water pressure gauge to remind you when it's time to change the filter. Forget tracking dates – rely on pressure readings. Its Twist-in filter design ensures quick, leak-free filter replacements in 3 seconds, which sets it apart from conventional RO systems.
Filter Replacement Reminder: The pressure gauge value is normal for 75-130PSI. If the value exceeds 130PSI, the RO filter needs to be replaced. If it is lower than 75PSI, the PP, CTO and ALK filters need to be replaced.

Contact UsThe only difference is water type output: the T1-400ALK delivers mineralized alkaline water, while the T1-400 provides nearly 0 TDS water. Choose based on your preference for mineral content.
Filter Replacement Schedule: All-in-one filter cartridge: Every 6-12 months depending on water quality and usage: Filter capacity: Each cartridge processes approximately 1,057 gallons of purified water Factors Affecting Replacement Frequency Water quality: Higher TDS levels in your source water (above 200 PPM) may require more frequent changes Daily usage: Heavy use (multiple gallons per day) shortens filter life Performance indicators: Replace when TDS levels start rising above 25PPM or flow rate decreases noticeably The system's twist-and-replace design makes filter changes quick and tool-free. Customers report that the all-in-one cartridge design simplifies maintenance compared to multi-stage systems where individual filters need separate replacement schedules.
No. DIY Installation is Possible: Comes with complete installation kit including faucet, tubing, and manua. Many customers in reviews mention successful self-installation. One reviewer specifically notes: "Installation was easy, just need to make sure you have a power outlet in reach of the cord and close to the cold water hook up"
Yes, the SimPure T1-400ALK has defined water pressure requirements, but its built-in pump adds flexibility: Operating Range: 14.5–116 PSI Built-in Pump: Automatically compensates for varying water pressures Automatic Operation: The pump activates as needed to maintain proper filtration This wide pressure range makes the system compatible with most residential water setups. The built-in pump is especially useful in situations where water pressure fluctuates, such as in RVs or areas with variable municipal supply, ensuring consistent performance at all time
