    About

    OASSAY - Innovation That Flows. OASSAY was born from a breakthrough in the lab. After five years of focused research, our partner team developed a revolutionary 3D porous, flexible filtration material - NanoFlex Carbon. Capable of removing bacteria, viruses, and heavy metals with impressive efficiency. Its feather-light weight and soft elasticity sparked a bold idea: what if we turned this breakthrough into a versatile, on-the-go purification solution for everyday life and outdoor adventures? That idea became our mission - to create outdoor drinking products that combine purification, safety, convenience, and aesthetics in one elegant form. Not just a tool, but a reliable companion for both everyday moments and wild adventures. At OASSAY, we believe clean water should feel effortless, beautiful, and always within reach. And we're not stopping here. Together with our users, we aim to keep exploring, keep evolving, and make this “solution” a trusted part of every journey - wherever it leads.
