Review: The Only Water Filtration System you will Even Need. - The Best Tasting Warter Ever. The only Water filter System you will ever need. After years of using a standard carbon block system, I finally made the switch—and I’m never looking back. This is hands-down the best water filtration system you will ever need. The water is incredibly pure and tastes almost like high-quality mineral water. There is honestly no comparison to anything else available. Plus, the installation was very simple, and the filtration-to-waste ratio is excellent. It is very affordable and has low cost of replacement filters. System perfectly fit under my sink and it took me about 30 min to install. Highly recommended!
Review: Review – Why I Chose This Model - After one week of use, I’d like to share my experience and explain why I chose this particular reverse osmosis system over others. There were two main reasons for my decision: 1. Filter flexibility (ALK to T33 option). This model allows you to replace the Alkaline (ALK) filter with a T33 carbon filter if needed. I wasn’t completely sure whether I would prefer alkaline water long term. With this system, I can simply swap one filter and get 0 ppm water if I choose. That flexibility was very important to me. 2. NSF certification. This system has internationally recognized NSF certification, which can be easily verified on the official NSF website. Unlike some brands that only pay for one-time testing, this certification provides ongoing credibility. For me, that really matters when it comes to water quality and safety. Packaging & Installation: Everything arrived well packaged and protected. The box includes many additional fittings for different installation scenarios — various tubing sizes and even the option to connect the system to a refrigerator. The instructions are clear and detailed. Installation took about 1.5 hours. The most difficult part was drilling a hole in the countertop for the faucet. I had to buy a diamond drill bit for that. My advice: buy a good-quality bit and watch a YouTube tutorial before drilling. I was surprised to learn that: 1. You need to keep the drill bit wet while drilling. 2. You should start drilling at a 45-degree angle. The unit itself is compact and doesn’t take much space under the sink. Water Quality Results Before installation, my tap water measured 176 ppm. After installation, it measured 70 ppm, because the ALK filter adds beneficial minerals back into the water. After one week, I performed a 14-parameter water test with the following results: Hardness: 50 Chlorine: 0 Iron: 0 Copper: 0 Nitrate: 0 Nitrite: 0 Calcium: 0 Total Chlorine: 0 Fluoride: 0 Alkalinity: 40 Carbonate: 180 pH: 7.5 Lead: 0 Bacteria: 0 Overall, the results are very reassuring. What I Would Improve I would like to see better filter replacement indicators. The current system for tracking filter life is not very informative. A clearer indicator or built-in reminder would improve the user experience. Overall Impression I am satisfied with this purchase. We drink this water daily, cook with it, and wash food with it. So far, the system performs as expected and gives me confidence in our water quality.

- ALKALINE REMINERALIZATION WATER: Exclusively designed to restore the natural alkalinity and mineral balance of water. The alkaline filter contains pure natural filter material without heavy metal pollution.

With a remarkable 1.5:1 pure-to-drain ratio, it minimizes wastage by only producing 1 gallon of wastewater for every 1.5 gallons of filtered water.

- NOTE: The SimPure T1-400ALK RO system enhances the pH level of filtered water by adding minerals through the alkaline filter. However, the TDS value will not reach 0 ppm. If you prefer filtered water with low TDS value, we suggest purchasing the SimPure T1-400UV reverse osmosis water filter, which provides clear water with a TDS level near 0 ppm when your tap water measures below 200ppm

### ⭐⭐⭐⭐⭐ Best Tasting Water !
*by C***G on January 4, 2026*

I recently installed this tankless under-sink RO system, and it’s been a fantastic upgrade for my home water quality. The multi-stage filtration removes a wide range of contaminants while the alkaline remineralization adds back beneficial minerals for better taste and balanced pH. The built-in UV sterilization gives extra peace of mind by helping to eliminate microbes, and the compact, tankless design saves precious space under the sink. Setup was fairly straightforward, and daily use delivers clean, great-tasting water on demand. A highly effective and efficient choice for anyone serious about pure drinking water
