I can confidently say that after 5 years of using this ispring in conjunction with the rest of my family it's certainly a worthy investment! The installation was relatively simple and easy to do even without technical experience. The system and parts are made with quality and all tubing that connects has safety clips that prevents disconnection/leakage. There is even an additional leakage detector that has a kill switch included to shut off the system in case of any leaking that is detected. My city water TDS is 490 and after the filtration system the TDS is between 20 to 30. System reduces TDS to zero at first and adds beneficial minerals afterwards. So I know whatever TDS you get at the end, it's only the good stuff. I like that the first filter housing is see-through, so you can see that after a few months the colors will start changing from white to a more copper brownish color. As an additional bonus the last mineral filter is see-through too. I went longer than the recommended schedule to change the main filters and 4 years later the RO-Membrane is still putting out the same TDS that I had in the beginning. This system definitely removes chlorine and fluoride. The reason I know is that I breed medicinal leeches and they do not tolerate any amount of chlorine or flouride. They will not survive it.Additionally, I would like to say something about their outstanding customer service. Recently, I have moved to a new apartment and had to get replacement parts due to normal wear and tear. Prior to talking with customer service I was expecting that the company was going to charge me an arm and a leg to get replacement parts since my filter system was way out of warranty. To my pleasant surprise, I spoke with Sean and he was very nice and helpful. Sean even sent those parts I needed to me for free with little to no hassle. What a wonderful customer service experience, that tells me that the company is 100% behind their product. If anyone has any questions feel free to contact me.
