Contact usStandard 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.
Yes. Most homeowners install it in 60 to 90 minutes. All fittings are push-connect, the tubing is color-coded, and the clear housing lets you verify that water is flowing properly without guesswork.
Stages 1 through 3 should be replaced every 6 to 12 months. The Stage 5 post-carbon and Stage 6 alkaline filter are replaced every 12 months. The central RO membrane typically lasts 2 to 3 years.
Yes. The 0.0001-micron reverse osmosis membrane removes up to 99% of lead, fluoride, PFAS, nitrates, heavy metals, pharmaceuticals, and microplastics.
Yes, provided the well water is microbiologically potable and operating within the 45–70 PSI pressure range. If your well water contains high iron or sulfur, pre-treatment may be advisable.
