Anions
Negative Oxygen Ions (NAIs)
Hailed as "Vitamins in the Air"
How are negative oxygen ions generated?
Negative ions are invisible, intangible, yet omnipresent. They are electrically charged particles formed when air molecules gain or lose electrons. Those with a negative charge are called negative ions, which are crucial for purifying the air and improving the ecological environment. Most airborne negative ions are generated when oxygen molecules capture free electrons released during ionization, often caused by high voltage or strong radiation. Hence, they are commonly referred to as "negative oxygen ions" and are hailed as the "vitamins in the air."
What are the health benefits of negative oxygen ions for the human body?
It promotes blood circulation, possesses antiviral and antibacterial properties, and helps eliminate odors. Long-term wear can contribute to long-term health and well-being.
What are negative oxygen ions?
Negative oxygen ions are often dubbed the "vitamins in the air." As charged air particles, they enter the body through the nose, mouth, or skin, much like vitamins from food, to help restore the body's natural balance. Generally, the concentration of negative oxygen ions in the air is considered a key indicator of how fresh and clean the air is.
The Generation Principle of Natural Negative Ions
Negative ions are invisible, intangible, yet omnipresent. When air molecules or atoms lose or gain electrons, they form charged particles known as ions. Those carrying a positive charge are called positive ions, while those carrying a negative charge are referred to as negative ions.
Negative ions are negatively charged gas ions in the air. When air molecules are ionized under high voltage or strong radiation, most of the free electrons generated are captured by oxygen. Therefore, air negative ions are commonly termed "negative oxygen ions." Simply put, gas molecules in the air that carry a negative charge are called negative ions.
These negative ions can purify the air and improve the ecological environment. They are also known as "vitamins in the air."
The Generation of Negative Ion Fiber
Originating from nature, returning to authenticity—weaving the essence of heaven and earth into a second skin.
Negative ion fibers or textiles are produced by incorporating rare earth minerals with trace radioactivity or natural minerals into textile materials through blend spinning technology, enabling them to generate negative ions. The weak radiation emitted by these rare earth minerals containing natural neodymium and uranium continuously ionizes airborne particles to produce negative ions. Additionally, natural minerals such as tourmaline and opal, which possess inherent electromagnetic fields, are utilized. These minerals are borosilicate substances with ring structures containing aluminum, sodium, iron, magnesium, and lithium, exhibiting both pyroelectric and piezoelectric properties. When subjected to minor changes in temperature or pressure, a potential difference (voltage) forms between mineral crystals. This energy ionizes the surrounding air, causing released electrons to attach to nearby water and oxygen molecules and convert them into airborne negative ions.
Our independently developed negative ion material is a high-tech substance integrating multiple functions including negative ion release, far-infrared radiation, antibacterial action, microbial inhibition, antiviral efficacy, and deodorization. It features high negative ion concentration, wash resistance, non-radioactivity, and non-attenuation characteristics.
National Standards for Negative Oxygen Ion Concentration
China's national standards for negative oxygen ion concentration involve specific regulations from different authorities and scenarios, mainly categorized into three types: recommended values from international organizations, domestic meteorological classification standards, and indoor air quality requirements.

National Indoor Air Quality Standards in China
支持从概念设计到生产制造的全流程应用，满足多样化创新设计需求
I. World Health Organization (WHO) Recommended Standards
The WHO provides clear recommendations for negative oxygen ion concentration in fresh air:
Basic Requirement: The concentration of negative oxygen ions in the air should reach 1,000–1,500 ions/cm³ to be considered "fresh air."
High-Quality Air Standard: When the concentration exceeds 2,000 ions/cm³, the air is classified as "very fresh," offering significant benefits for human health and environmental comfort.
II.Ecological Environment Classification Standards by China Meteorological Administration
The China Meteorological Administration has established a grading system for negative oxygen ion concentration in natural environments such as forests and scenic areas:
Level 1 (Very Fresh): Concentration ≥ 1,200 ions/cm³ – suitable for prolonged outdoor activities.
Level 2 (Relatively Fresh): Concentration between 500–1,200 ions/cm³ – good air quality, though slightly below the optimal level.
Level 3 (Average): Concentration between 100–500 ions/cm³ – no significant air pollution, but limited purification capacity.
Level 4 (Not Fresh Enough): Concentration ≤ 100 ions/cm³ – potential air pollution risks that require attention.
III. National Indoor Air Quality Standards in China
The *Indoor Air Quality Standard (GB/T 18883-2002)* specifies requirements for negative oxygen ion concentration in living and working environments:
Daytime Standard: Indoor concentration should be ≥ 600 ions/cm³ to ensure respiratory health during daily activities.
Nighttime Standard: Concentration should be ≥ 400 ions/cm³ to accommodate the body’s metabolic needs during rest.
