Rated as one of the best international brands, this RO system is fully certified by international NSF/ANSI testing standards. The Dumaguete Water District Lab gave it a top rating for purity. Few RO systems can match that. This is the upgraded version of the well-known T1-400UV system. The T1-500UV provides toxin, bacteria and virus free water.
This system can produce 80,000 gallons (300,000 liters) of water before filters need replacing. The tankless design eliminates the possibility of mold that has to be purged from systems that have a water holding tank. it comes with all filters pre-installed and has a filter replacement alert gauge.
SIMPURE T1-500UV Under the Sink Reverse Osmosis
8-Stage Filtration Technology: Tankless RO System
The T1-500 UV under-sink tankless reverse osmosis system is NSF/ANSI 58 compliant and has been tested and certified by SGS. Featuring innovative 8-stage water filtration, it effectively removes 99.99% of over 1,000 contaminants, including viruses, bacteria, chemicals (PFAS: PFOA/PFOS, Pharmaceuticals), heavy metals (Lead, Arsenic, etc.), TDS (over 99.87%), chloride (over 99.49%), fluoride (over 99.77%), microplastics, and more (see the SGS test report for details). This 8-stage tankless RO system is also BPA- and lead-free, making it a safe choice for under-cabinet installation.
Best Tankless Reverse Osmosis System for Under Sink with Nearly Zero TDS Reduction
The SIMPURE high-efficiency tankless UV reverse osmosis system removes contaminants as small as 0.0001 microns in diameter. Equipped with exclusive filtration technology, it achieves a TDS removal rate of 95%, with the highest rate reaching 99.99%, making it the best reverse osmosis system for reducing TDS.
The SIMPURE T1-500UV lowers the TDS of tap water with a level of ≤ 200 PPM to nearly 0 PPM, while water with 200-500 PPM can be reduced to 25 PPM or lower. Additionally, this top-rated tankless reverse osmosis system features a high-precision water pressure gauge and four filters, offering greater efficiency and longevity compared to similar products on the market.
UV Sterilization in T1-500: Eliminate 99.99% of Microorganisms
Equipped with a UV sterilizer, this tankless 8-stage reverse osmosis water filter system effectively removes harmful bacteria such as E. coli, coliforms, salmonella, and various viruses and water parasites. It eliminates up to 99.99% of harmful microorganisms in water. Combined with the 7-stage RO filtration system, this tankless RO+UV water filter provides and 8th stage of purification for your drinking water compared to standard under-cabinet reverse osmosis systems, making it especially recommended for well water sources. Just buy one and taste the difference!
Tankless & No Waiting Under Sink Design: Best Reverse Osmosis Tankless System
The T1-500 UV under-sink reverse osmosis tankless system requires only a fraction of the space under your sink, saving up to 70% of the area. This tankless RO water filter system delivers a fast flow rate of 1900 liters per day (1.3 liters per minute), providing pure water instantly on demand without any waiting. It eliminates the risk of secondary pollution that can occur with traditional tank systems, which require 2-4 hours for the tank to fill and eliminate the possibility of bacteria, microbiological contaminants or viruses that may collect and grow in the stored water in the tank.
A Truly Sustainable Under Sink Tankless RO System
The SIMPURE T1-500UV tankless reverse osmosis water system is equipped with a built in boost pump, delivering a faster water flow of 500 GPD (2 liters per minute) producing a cup of water in about 5 seconds.
Less waste than other RO systems, this tankless UV reverse osmosis system features a low pure-to-drain ratio.
