Filtration Stages & Maintenance

Stage 1: Polyspun Sediment Pre-Filter
Crafted from spun-bonded polypropylene, this filter captures large debris like rust, sand, dirt, and silt, acting as a formidable barrier that protects the carbon filter in Stage 2.

Stage 2: 0.5 Micron Coconut Carbon Block
Not all carbon is created equal. This filter uses German-made Celanese ultra-high molecular weight polyethylene and HAYCARB carbon. It offers 10x the adsorption capacity of standard filters, guaranteeing 99.99% chlorine removal. (Bonus: We include a free chlorine tester so you can see the results yourself!)

Maintenance: For optimal performance, we recommend replacing both cartridges every 6 to 12 months, depending on your local water quality and daily usage volume.
