Review on πŸ’¦ Enhance your Water Quality with the iSpring F9K Replacement 6 Stage Filtration by Jorge Tupou

Revainrating 5 out of 5

Unbeatable price and fantastic customer service

I didn't know anything about home reverse osmosis systems until this morning, but I'm tired of paying someone over $250 a year to replace cartridges. My home reverse osmosis system is not made by iSpring and I wasn't sure if their cartridges would fit. I called support. Don from iSpring looked at the pictures and showed me the steps to connect hoses with quick disconnects. After the call, I was able to replace steps 1, 2, 3, 5, and 6 in under 30 minutes on my first try! Your products are very beneficial. Everyone should know how to change reverse osmosis filters yourself, because thanks to companies like iSpring, it's that easy. An interesting thing I learned this morning while changing the filters and fiddling with the tubes: There are two ways to hook up a six stage system. iSpring has a circuit consisting of 1, 2, 3, 4, tank, 5, 6, faucet. The plumber who hooked up my system did 1, 2, 3, 4, 6, tank, 5, faucet. If you follow the iSpring configuration, the first half pint of water is residual water from stage 6, so you'll briefly see TDS up to 200ppm because the water has been mineral-packed for a while. However, if you add more water, the TDS can drop to 33ppm, which is good. However, if you use the second configuration, your TDS reading will be much more stable and around 35-45ppm as any residual high TDS water in the aquarium will be normalized (diluted). and you can definitely feel the difference. if all this sounds Greek to you, don't worry, your water still tastes great, but if you understood my very poor description, try it and you will definitely like it.

Pros
  • Reverse Osmosis Membrane not only removes harmful pollutants but also several beneficial minerals. As a result, a standard 5-stage reverse osmosis system will produce slightly acidic water with a pH of 7.0 or lower. The alkaline mineral filter produces alkaline water with restored healthy minerals such as naturally occurring calcium, magnesium and potassium ions that balance the pH of reverse osmosis water.
Cons
  • Long Lead Time
