Negative ions are microscopic charged particles with negative charge which are generated when neutral atoms or molecules acquire one or more electrons.
Plasma is one of the four fundamental state of matter. It contains a significant portion of charged particles – ions and/or electrons. The presence of these charged particles is what primarily sets plasma apart from the other fundamental states of matter.
Bipolar ions are generated from bipolar ionization (also called needlepoint bipolar ionization), which is used in HVAC systems or portable air cleaners to generate positively or negatively charged particles.

A negative ion generator is a device that uses high voltage to ionize air molecules. When a negative ion generator is working to generate negative ions, the input AC or DC current will first be raised to AC high voltage and then converted to DC negative high voltage. Through a release tip made of metal or carbon, DC negative high pressure will release a large amount of electrons. These electrons will then be captured by oxygen molecules in the air to form negative ions. Negative ions can absorb small particles in the air because they are negatively charged. Particles will gain weight due to the absorption of negative ions and eventually fall to the ground. Negative ions can also combine with bacteria and lead to a structural change and realize a sterilization effect.

• Can be used for both dust removal and sterilization.
• Make oxygen molecules easily absorbed by human and thus enhance the immunity.
• The bactericidal effect exceeds that of 3% peroxyacetic acid. Can better purify the air with the filtration and adsorption from HEPA.
• Extend the shelf life of vegetables and fruits and maintain their nutritional content.
• Sterilization can be achieved in the presence of human.

• The formation of ozone during the generation of negative ions should be controlled.
• There is no evidence that negative ions can kill viruses that have no cellular structure.

A negative ion generator can be used in home, offices, schools, hospitals, etc.

A plasma generator can raise low voltage to positive and negative high voltage. The high voltage can ionize the air to produce a large number of positive and negative ions. There are usually about 1.5 times as many negative ions as positive ones. In the air, the neutralization of the two types of ions will release energy to sterilize the nearby bacteria. Due to the quantity advantage, excessive negative ions can also achieve the effects of dust removal, smoke elimination, odor elimination, and improve air quality.

• Can achieve a broad-spectrum sterilization from bacteria to spores.
• Can realize the sterilization of medical or electronic instruments which are sensitive to heat at room temperature.
• Suitable for non-chemical sterilization of items that cannot be sterilized with alcohol.
• No dead angle problem exists in ultraviolet sterilization.
• No cooling time problem after a high temperature sterilization.
• No longtime ventilation problem after chemical treatments such as ethylene oxide.
• No ozone or UV residue problems after the sterilization.
• Same sterilization effect can be achieved with 1/3 of the energy consumption of UV sterilization.
• Compared with around 5 years of service life in ultraviolet sterilization products, a plasma ion generator can be used for over 10 years.
• No need to replace any consumables.

• High temperature spark or arc discharge caused by high temperature discharge make it not a good choice for biomedical applications.
• Dielectric barrier discharge, surface discharge, plasma jet and other methods used in the generation of low-temperature plasma are not suitable for the manufacture of equipment for large-area sterilization.

A plasma ion generator can be used in hospitals, pharmaceutical factories, schools, airports, conference rooms, etc.

Both carbon brushes and stainless steel needles are commonly used in the production of ion generators. Compared with these two choices, carbon brushes are more impact-resistant and less prone to passivation. Ion generators with carbon brushes can produce a constant and reliable density of negative ions and bipolar ions. Stainless steel needles can achieve a more concentrated transmission of ions, and avoid the accumulation of fine dust from the air.

The lead time may differ from one order to another. The delivery time will be decided according to the quantity of products included in an order. For details, please consult our customer service.

All of our products will be thoroughly tested before the delivery. They will be tested for optimal usage and conservation conditions to provide the best performa. The test includes the following 3 steps:

1. Components income check

Upon entering the factory, all components (e.g. transformers, carbon brushes, needles, high Voltage diodes) will be tested according to AQL Major 1.0/Minor 2.5.

2. Input process check

After the production is finished on the production line, more tests will be conducted on both their appearances and their functions.

3. Finish pack check

All of our ionizers will be subjected to an ion concentration test by a concentration tester and an output voltage test by a high voltage probe. Once finished, they can be put into bags for shipment.
