How Reverse Osmosis Systems Work

Reverse osmosis systems use a multi-stage filtration process to purify water. The process forces water through a semi-permeable membrane that blocks contaminants while allowing clean water to pass through.

A typical RO system includes:

  • Sediment pre-filters
  • Carbon filtration stages
  • Semi-permeable RO membrane
  • Post-filtration polishing filter
  • Dedicated storage tank
  • Faucet dispensing system

This layered filtration produces highly purified drinking water.
