Filter-Free Low-Temperature Plasma Wearable Air Purifier and Personal Air Sterilizer with 21-Hour Runtime

The VD‑NC01 is a compact personal low‑temperature plasma air sterilizer built for individual micro‑environment air care. Adopting DBD (Dielectric Barrier Discharge) dual‑tube plasma technology, it actively treats surrounding air without filter elements. It suppresses harmful bacteria and viruses, and decomposes formaldehyde, benzene, and multiple volatile odor‑causing substances.

Ultra‑compact and lightweight at ≤58g, it comes with a lanyard and key‑chain for easy portability. Low‑noise performance enables all‑day use in work, rest, and travel scenarios. Trace ozone output supports safe human coexistence in personal small‑space applications.
