Spring Rain's Reverse Osmosis System

This under-the-sink reverse osmosis system is tested and certified to NSF/ANSI Standards 42, 53 (includes P473), 58 and 401 to effectively reduce 88 contaminants including...

  • 95% of Flouride
  • 95% of Mercury
  • 97% of Chlorine
  • 97% of Arsenic
  • 99% of Lead
  • 99% of Asbestos
  • And much more...

Our system is specially engineered to outlast other similar systems while maintaining the benefits of healthy minerals, and to perform better overall via unique combination of features:

Features:

  • Pentair GRO High Recovery Membrane which has an industry best 1:1 ratio which means it wastes half the water of traditional membranes
  • 1 micron sediment pre filter
  • 1 micron catalytic carbon pre filter
  • Your choice of 2, 3 or 4 gallon storage tanks
  • Post carbon & remineralization filter to allow small amounts of healthy minerals back into the water

A reverse osmosis system removes contaminants from unfiltered water. The system pressure forces water though a semipermeable membrane. To provide clean drinking water, water flows from the more concentrated side, or the more contaminated side, of the membrane to the less concentrated side, or has fewer contaminants. This produces fresh water called the permeate. The wastewater left over is called the waste or brine. The semipermeable membrane has small pores that block contaminants, but it allows water molecules to flow through.

In the osmosis process, water becomes more concentrated as it passes through the membrane to obtain equilibrium on both sides. However, in reverse osmosis, it blocks contaminants from entering the less concentrated side of the membrane. An example of this is when pressure is applied to a volume of saltwater during reverse osmosis, the salt is left behind, and only clean water flows through.
