How a Reverse Osmosis System Works

Have you ever wondered what actually happens under your sink when you turn on your drinking water faucet?

This is the full journey of water through a reverse osmosis system.

Step by step.

Step 1: Cold Water Feed

Everything starts with your cold water line.

  • Water enters the system from your home’s cold water supply
  • This line feeds directly into the reverse osmosis manifold

This is the starting point for filtration.

Step 2: Sediment Filter

The first filter is the sediment filter.

  • Catches dirt, sand, rust, and debris
  • Acts like a net for larger particles
  • Protects the filters that come next

If sediment reaches the membrane, it shortens its life. This filter helps prevent that.

Step 3: Carbon Filter

Next, water flows through a granulated activated carbon filter.

  • Reduces chlorine and chemical contaminants
  • Improves taste and smell
  • Prepares water for the membrane

This step helps protect the core of the system.

Step 4: Reverse Osmosis Membrane

This is the heart of the system.

  • A semi-permeable membrane
  • Removes dissolved solids and unwanted contaminants
  • Separates clean water from waste water

This is what makes it a true reverse osmosis system.

Without this membrane, it’s not reverse osmosis.

Step 5: Remineralization Filter (Optional)

After purification, some systems add minerals back in.

  • Adds healthy minerals
  • Improves taste
  • Raises pH for more balanced water

Think of it like a daily vitamin for your water.

Step 6: Storage Tank

Clean water moves into the storage tank.

  • Holds purified water until you need it
  • Keeps water ready on demand
  • Helps maintain steady pressure at the faucet

This tank is why reverse osmosis systems deliver water when you want it.

Step 7: Delivery Pump (If Needed)

If the faucet or refrigerator is far from the tank, a pump may be used.

  • Pressurizes water leaving the tank
  • Maintains strong flow
  • Helps prevent slow delivery

Not every setup needs one, but longer distances often do.

Step 8: Accumulator Tank and Final Filter

Before water reaches your glass, it passes through one final stage.

  • Accumulator tank helps stabilize pressure
  • Final polishing filter improves taste and odor
  • Uses activated carbon for a clean finish

This step gives the water its final touch.

Step 9: Fresh Water at Your Sink

After all that filtration, water reaches your faucet.

  • Clean
  • Filtered
  • Ready to drink

Every drop has passed through multiple stages designed to improve water quality and taste.

Is Reverse Osmosis Right for Your Home?

Reverse osmosis systems are a great option for any drinking water source.

  • PFAS
  • Chlorine
  • Heavy metals
  • Dissolved solids
  • Unwanted taste and odor

Municipal water. Well water. Refrigerator lines.

If it’s water you drink, reverse osmosis can help.
