## Description

SimPure Tankless Alkaline Reverse Osmosis System, UV Under Sink RO Water Filter System 400GPD, 1.5:1 Pure to Drain, Built-in Booster Pump (T1-400ALK)

Review: Easy installation with great performance - I ordered the SimPure ROULP-3012-400-T1, to install as our main filtration unit in the kitchen. With its capability to remove over 99.99% of more than 1,000 contaminants—including harmful viruses, bacteria, microplastics, and chemicals like PFOA/PFOS—this system offers peace of mind for anyone concerned about water quality. The comprehensive removal of heavy metals such as lead and arsenic makes it a particularly compelling choice for households in areas with questionable water sources. One feature that impressed me is the alkaline remineralization capability. Not only does this system effectively purify water, but it also enhances its quality by restoring essential minerals such as calcium, magnesium, and potassium. The result is an alkaline, mineral-rich beverage that tastes refreshing and contributes to better overall health. Unlike some ionizers, this system delivers a higher pH with no chemicals or heavy metals, making it a safer option in my opinion. The inclusion of a UV sterilizer is another highlight of the SimPure R/O system. This automatic component eliminates bacteria and other microorganisms, ensuring that the purified water remains uncontaminated. Moreover, the tankless design is a game-changer—it not only maximizes space under your sink but also provides fresh water on demand, further reducing the risk of any secondary contamination. With a production capacity of up to 400 gallons per day and an impressive pure-to-drain ratio of 1.5:1, this system is undoubtedly more eco-friendly than traditional reverse osmosis systems. The efficiency in minimizing waste while providing high-quality purified water is great. Installation is fairly simple and the instructions are detailed, making installation time right under 30 minutes. This system is so much easier with the included pump, eliminating the need of a bulky tank. While the system enhances the pH level of filtered water, the Total Dissolved Solids (TDS) won't reach 0 ppm. If you are looking for lower TDS values, look at the SimPure's T1-400UV option. The SimPure ROULP-3012-400-T1's ability to provide not just purified water but also essential minerals makes it a worthy investment for anyone looking to improve their water quality and overall health. I highly recommend it!
Review: Great Product! - I’ve now been using this product daily for 2 years and using water testing devices to verify quality. This product is very good, works well, and produces pure, clean, great tasting water.
