    Plumbing Connectors


    The Atmos AIO uses the power of atmospheric oxygen to rid your well water of iron, sulphur, and manganese. Say goodbye to stained tubs & toilets, stained laundry, metallic-tasting water, and foul smells when someone has a shower or fills the kitchen sink.

    We've leveraged two decades and thousands of customer interactions to design this highly effective and DIY-friendly chemical-free system. The Atmos-AIO is capable of removing high concentrations of contaminants due to its unique media mix:

    Katalox Light: The most effective catalytic oxidizing media on the market

    Zeolite Sand: Renowned for its particle-capturing capabilities

    Calcite + Corosex: Granular media boosts pH to supercharge the filtration process

    Filter Gravel: Supports the media bed and offers coarse particle filtration
