Overview

Understanding Plasma Technology Plasma is a material form consisting mainly of free electrons and charged ions, often considered to be the fourth state of matter, called the plasma state. Plasma has very high conductivity and strong coupling with electromagnetic fields. Strictly speaking, plasma is a gas mass with high energy and dynamic energy, which contains a large number of reactive oxygen ions. High-energy free radicals and other components can easily react with bacteria, molds, spores, and proteins and nucleic acids in viruses to denature them and cause various microorganisms to die. The product generates a small amount of ozone while generating plasma, not sufficient to be harmful to the human body and the internal 3G filter can effectively filter the trace amount if present.

Main sterilization: Plasma technology
Sterilization strength: Plasma density 3.46×1014 m-3
Effective against type of microorganisms: Common bacteria in the air
Sterilization rate for staphylococcus albus (8032) ≥99.9%

Ideal Use It is suitable for use in enclosed environments such as library, museums, office buildings and homes, where the air is confined within a space. The LAS302 can eliminate bacteria and viruses at 99.9% efficacy.

How does the LAS302 work?

Sterilization function: Plasma Generator
Through the rotating of fan blades, the product pumps indoor air from the bottom and releases out from the top, allowing the air to filter via prefilter, plasma generator, and 3G filter
The operating principle is illustrated as below:
