Our municipal tap water here in Arizona has a strong mineral and chlorine bite. Installed the Ispring Rcc7Ak 6 Stage Reverse Osmosis System under our kitchen sink in about an hour and a half. The quick-connect fittings made plumbing straightforward with zero leaks. Flow rate from the dedicated faucet is strong and fills a large glass in seconds. Tea, coffee, and ice taste completely pure now.
Replaced an old bulky tank system with this Ispring Rcc7Ak 6 Stage Reverse Osmosis System. Having full access to our cleaning supplies under the sink again is fantastic. The real-time filter life indicator is very convenient, and the water tastes noticeably crisper than standard pitcher filters.
Arrived in double-boxed commercial packaging with all adapters and color-coded tubing included. Hooked it to both the sink faucet and our refrigerator ice maker. Ice cubes are crystal clear and there is no plastic aftertaste.

Standard RO systems remove all minerals, resulting in slightly acidic, flat-tasting water. The iSpring alkaline filter restores natural minerals such as calcium, magnesium, and potassium, creating a balanced pH of 8.0–9.0 and a natural mountain-spring flavor profile.
