The Atmos 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 our most effective chemical-free system to date. The Atmos 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
