PlaDeo is a Korean startup product that uses reactive oxygen species (ROS) instead of aluminum or fragrances to eliminate odor. It recently launched on Indiegogo and is CE-certified. No chemicals, no residue—just a portable plasma-based solution. The technology was validated by a 2024 peer-reviewed study published in Nature's Scientific Reports.
