8-Stage Filtration Technology: SimPure T1-400 Tankless RO System
SimPure T1-400 under sink tankless reverse osmosis system is NSF/ANSI 58 compliant and has been tested and certified by SGS. With innovative 8-Stages water filtration, it can remove 99.99% of 1,000+ contaminants, including chemicals (PFAS: PFOA/PFOS, Pharmaceuticals), heavy metals (Lead, Arsenic, and etc), TDS (>99.87%), chloride (>99.49%), fluoride (>99.77%), microplastics, and more. (See SGS Test Report for more details) This 8 Stage tankless ro system is also a BPA and Lead-free under cabinet reverse osmosis system.
Best Tankless Reverse Osmosis System for Under Sink with TDS Reduction Nearly Zero
SimPure High-Efficiency tankless reverse osmosis system for Under Sink removes contaminants 0.0001 microns in diameter or larger. This tankless RO water filter system is equipped with SimPure exclusive filtration technology, it reduces TDS by up to 95%—bringing tap water with ≤200 PPM TDS down to nearly 0, and water with 200–500 PPM down to as low as 25 PPM. This best tankless reverse osmosis system is also equipped with 4 long-lasting filters and a precision water pressure gauge; it outperforms standard RO systems in both efficiency and durability.
Tankless & No Waiting Under Sink Design: Best Tankless Reverse Osmosis System with 400 GPD
SimPure T1-400 under sink reverse osmosis tankless system requires only a fraction of the space under the sink, saving up to 70% under-sink space. The SimPure T1-400 tankless RO water filter system offers a faster flow rate of 400GPD (0.28 gallons per minute), supplying pure water instantly on demand, without waiting. There is no possibility of secondary pollution. (RO systems with tank require at least 2-4 hours for the tank to fill before use.)
Sustainable Tankless Reverse Osmosis System – Save Water with 1.5:1 Pure-to-Drain Ratio
SimPure T1-400 tankless reverse osmosis water system equipped with a boost pump and offers faster water flow (400GPD, 0.28 gallons per minute) and can filter a cup of water in about 12 seconds. Compared to traditional RO systems, SimPure tankless reverse osmosis system has a low pure to drain ratio of 1.5:1 ( Produces only 1 gallon of wastewater for every 1.5 gallons of pure water). This means you can reduce your own plastic waste – saving money on bottled water.
Filter Replacement Alerts & Twist-in Filter System, Filters can be Changed in 3 Seconds
SimPure T1-400 tankless 8 stage water filter system is equipped with a water pressure gauge, which reminds you to replace the filter more intelligently and scientifically, without having to remember the date of the last filter change. And Compared to typical RO systems, its unique twist-in filter design avoids kinks and leaks, making filter replacements a breeze and easy replacement in 3 seconds.
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 T33 filters need to be replaced.
SimPure High Quality Tankless Water Filter with RO System Really Worths Your Trying!
Here is the installation process of SimPure T1-400 series under sink ro system. Follow the steps in the video and you will be surprised by this excellent tankless reverse osmosis system!
Note: Please kindly note the extra pressure tank is required if you need to connect the refrigerator/ice maker or another device to the system and not included in the package, you need purchase it separately.

Contact Ushe 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 manual 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 T1-400 Reverse Osmosis System has specific water pressure requirements, but with a built-in pump for flexibility: Water Pressure Requirements: Operating range: 14.5-116 PSI (pounds per square inch) Built-in pump: Compensates for varying water pressures automatically Automatic operation: Pump activates as needed to maintain proper filtration This wide pressure range makes it suitable for most residential water systems. The built-in pump is particularly beneficial because it ensures consistent performance even when your water source pressure fluctuates, which is common in RV applications or areas with variable municipal water pressure."
Yes. RV-Friendly Design: Compact size: 15.6" x 5.3" x 15.7" fits well in limited RV storage spaces Tankless design: Saves precious under-cabinet space compared to traditional RO systems with bulky tanks Built-in pump: Works effectively with varying water pressures (14.5-116 PSI) 400 GPD capacity: Provides ample fresh water for RV living
