Portable Car Plasma Air Purifier — Product Details

Product Overview

The Junxintang Portable Car Plasma Air Purifier is a compact, USB-powered air purification device designed for vehicles, offices, and small enclosed spaces. Combining cold plasma ion technology with an optional H13 True HEPA filter, it actively neutralizes airborne pollutants, eliminates odors, and refreshes the air around you—whether you are driving, working, or traveling.

How It Works: Cold Plasma Technology

The purifier generates low-temperature plasma through an electrical discharge process. This plasma contains high-energy electrons, positive and negative ions, and reactive oxygen and nitrogen species (RONS). These active species oxidize bacterial cell membranes and viral envelopes, effectively inactivating airborne microorganisms. At the same time, charged particles are attracted to and intercepted by the device's internal filtration media.

Unlike passive HEPA-only purifiers that rely solely on air passing through a filter, plasma technology works actively: ions are released into the surrounding air, allowing purification to extend beyond the device itself. Research shows that plasma-based air filtration systems can achieve filtration efficiencies above 91% while successfully inactivating bacteria, fungi, and up to 99.32% of the H1N1 virus in diverse environments.

Key Features

• Cold Plasma Ion Generation — Releases millions of negative ions and reactive species to neutralize pollutants, pathogens, and odors in the air

• Active + Passive Dual Purification — Plasma ions provide active purification throughout the space, while an optional H13 True HEPA filter captures 99.97% of fine particles including dust, pollen, smoke, and pet dander

• USB-Powered, Battery-Free Operation — Powered via USB Type-C, eliminating battery risks and protecting your vehicle's electrical system. No built-in battery means zero fire hazard and minimal energy consumption

• Compact & Portable Design — Lightweight and fits easily in a car cup holder, center console, or desktop. Weighs approximately 190–240g, with dimensions around 68 × 165 mm

• Ultra-Quiet Operation — Operates at whisper-quiet noise levels (approximately 35 dB), ensuring it does not interfere with driving or conversation

• Optional Aromatherapy Function — Compatible with essential oil pads, allowing you to add a personalized, calming scent to your car or workspace

• Low Power Consumption — Draws only 1.5–2.5W, making it energy-efficient for continuous use
