πŸ”¬ How It Works

Five Stages, One Job: Genuinely Clean Water

Reverse osmosis on its own is powerful, but pairing it with pre- and post-filtration stages is what makes the system as effective and long-lasting as it is. Here's what each of the five stages is doing, conceptually, as your water passes through.

  • β‘ 

    Sediment Pre-Filter

    The first stage strains out sand, silt, rust, and other visible particles before water moves any further β€” protecting the finer filtration stages downstream.

  • β‘‘

    Carbon Filter β€” Chlorine & Taste

    A carbon filtration stage targets chlorine and the taste and odour it leaves behind, giving the water a noticeably cleaner profile before it reaches the membrane.

  • β‘’

    Second Carbon Filter β€” Fine Polish

    A second carbon stage catches additional chlorine and organic compounds the first stage didn't, further protecting the membrane and improving taste.

  • β‘£

    The Reverse Osmosis Membrane

    The heart of the system. Water is forced through a semi-permeable membrane fine enough to reject a wide range of dissolved contaminants β€” including lead, nitrates, and fluoride β€” while letting purified water pass through.

  • β‘€

    Post-Filter Polishing

    A final carbon polishing stage refines the water one last time right before it reaches your faucet, removing any last trace tastes for the cleanest possible glass.
