Seoul, South Korea, December 9: A South Korean company, Palsoo, has unveiled a portable sterilization system that utilizes regular tap water to eliminate 99.8% of airborne bacteria and viruses effectively.
This technology, which combines plasma activation with solar charging, offers a sustainable solution for sanitation in areas lacking electricity or facing harsh conditions.
During the CES 2025 Global Media Meet-up event at the AVING News MIK Basecamp in Seoul on December 9, the company’s CEO, Jang Palsoo, explained how the system works.
From tap water to disinfectant
The portable sterilizing sprayer has a lithium-ion battery that can be charged using solar power.
This allows the device to be operated in remote locations, making it particularly useful in regions with limited infrastructure.
When filled with tap water, the device converts it into a sanitizing aerosol almost instantly. This capability enables users to disinfect private and public spaces, promoting a cleaner environment for everyone.
The sprayer aims to combat airborne pathogens and plays a crucial role in agricultural practices, supporting eco-friendly farming methods and ensuring regular sanitation in poultry, livestock, and pig farms.
The technology behind this portable sanitizing system generates plasma at atmospheric pressure and engages various active species, including radicals and ions, with water.
The result is Plasma Activated Water (PAW), which exhibits significant antimicrobial properties.
This environmentally safe water treatment method can help manage odors and prevent spreading infectious diseases linked to humans and animals.
Eliminating bacteria, viruses
The growing challenges climate change presents underscore the need for such technology.
With increasing natural disasters like droughts and floods, many underdeveloped nations face declining agricultural productivity and significant food supply instability.
These regions often grapple with inadequate sanitation and the spread of waterborne diseases such as malaria, cholera, and typhoid.
Furthermore, limited access to electricity and poor medical infrastructure hampers effective responses to harmful pathogens.
Palsoo’s portable sterilization system seeks to address these urgent issues by providing a versatile tool that can be used in various environments without reliance on conventional power sources.
The introduction of plasma-activated water benefits multiple sectors, from agriculture to public health, as it can also serve as a liquid fertilizer due to its nitrogen content.
Helping agriculture
In addition to its sanitation capabilities, the technology can enhance agricultural practices by improving seed germination rates and promoting healthier plant growth throughout the entire agricultural cycle.
This process, dubbed “Plasma Farming,” encompasses all stages from farming to food consumption, enabling a more sustainable and efficient system.
The application of plasma technology extends to various stages of the food supply chain, including seed treatment, harvesting, storage, and even cooking.
For instance, plasma-treated seeds germinate faster and develop more quickly, leading to higher yields. Furthermore, plasma treatment can help eliminate ethylene gas during fruit storage, which reduces spoilage and extends shelf life.

This innovative technology is pollution-free and easy to adapt to new materials and processes, making it a promising option for various industries.
Palsoo is set to showcase this state-of-the-art portable sterilization system at the CES 2025 event in Las Vegas from January 7-10, 2025, offering a closer look at how their product can transform sanitation practices and enhance agricultural efficiency worldwide.
Participation in this event highlights the company’s commitment to addressing pressing global challenges through advanced technology.
