STAGE 1 Cartridge:

INERT POLYPROPYLENE (PP) SEDIMENT FILTRATION

This primary stage, utilizing an inert, melt-blown Polypropylene (PP) filter media, forms the critical first line of defense in the multi-stage system. Specifically designed as a depth filter, it creates a robust physical barrier that mechanically sieves out relatively large, heterogeneous particulates. A precision-engineered pore size of 5 microns (µm) ensures the comprehensive and accurate exclusion of common aquatic contaminants, including sand, silt, biological detritus (sediment), and fragmented scale deposits derived from aging infrastructure. By ensuring a low initial pressure drop, this stage maximizes water flow rate while meticulously safeguarding subsequent, more sensitive filter media from particulate fouling and premature capacity depletion.
