This is by far the best deal on water filters for my reverse osmosis system. You will receive six tube filters and three post-filters as well as a reverse osmosis membrane of each type. They call it a "3 year" filter kit, but you should probably replace your reverse osmosis membrane more often than every 3 years. Works just as well as the original filters that came with the kit. With this system, I consistently get less than 15ppm. I just measured and it was 12ppm with an incoming city of 194ppm. I'm not sure, but I think the fifth level increases the PPM. I remember reading this but can't find the source. If so, then the system is even more efficient. I had the iSpring reverse osmosis system in my home almost as soon as I received it. I've plugged it in and put it in the faucet and my fridge and am happy to have clean water for drinking and cooking. My sister always praised how clean and tasty our water was, so started a conversation about water quality and purification methods (to be honest, I originally bought a reverse osmosis system for chameleons, not for me). Fast forward a few months and my brother-in-law calls me to see what a similar system is available. Eventually he got the exact same system for fear the water wouldn't be what my sister expected. My sister is also happy with her system and I'm certainly happy to pay such a small price for a few years of pure, great-tasting water.
