Bring the forest’s oxygen-rich haven into your everyday life! Pusen Yuan and Shui Lizhi forge a strategic partnership to safeguard every breath.

Pusengyuan and Water Lychee Through the establishment of a deep strategic partnership, the two parties will leverage “water-based negative oxygen ions” as the core technology to integrate end-to-end resources across technology, products, and distribution channels, jointly driving innovation and upgrading in the negative-ion health industry and delivering comprehensive, high-quality respiratory health solutions for hundreds of millions of users.

After five years of research and development, this technology had, as of 2025, filed six trademark applications and 74 core patent applications, including 51 invention patents, 4 PCT patents, and 2 U.S. invention patents.

Unlike conventional air-purification technologies, water-based negative-ion technology—which mimics the powerful impact of a waterfall—continuously releases high-concentration, highly active negative ions. This not only efficiently breaks down airborne pollutants such as formaldehyde, PM2.5, bacteria, and viruses, but also elevates indoor and in-car air quality to “forest-level” freshness, truly delivering the dual benefits of purification and health enhancement.

As evidenced by the authoritative test reports presented at the exhibition, Shui Lizhi products achieve removal rates of up to 99.9% and 99.99% for various pollutants, providing a solid safety barrier with concrete, measurable data for every breath you take.

Through this strategic partnership, the two companies will integrate their technological and channel resources to create end-to-end air-purification solutions for in-vehicle, home, and commercial settings, bringing forest-level fresh air to every space. Looking ahead, we will harness technology to promote health, turning every breath into a healing experience and jointly unlocking a new blue ocean in the negative-ion health industry!
