Reverse Osmosis Domestic Systems

Reverse osmosis provides high-quality drinking water by separating dissolved contaminants through a fine membrane.

This collection contains our domestic and high-output direct-flow RO equipment, along with the matching replacement filters needed to keep compatible systems operating correctly.

Why choose reverse osmosis?

  • Reduces a broad range of dissolved contaminants
  • Improves drinking-water taste and clarity
  • Suitable for homes, offices and higher-demand applications
  • Direct-flow systems can deliver purified water without a bulky storage tank

Choose a system or replacement pack

If you are installing reverse osmosis for the first time, choose a complete system and confirm your water pressure, plumbing connection, available space and expected daily demand.

If you already own a Direct Flow RO system, check the exact model before ordering replacement filters. Replacement packs are model-specific and are not complete filtration systems.

Get the sizing right

Membrane output varies with incoming pressure, temperature and water quality. For help selecting a system, contact The Filter Guy with your water source, household or workplace demand, available space and any water-test information you have.

We can also quote larger or specialised RO systems that are not listed online.
