Item detailsMaterials, dimensions, what is in the box
Negative ion generator with Micro USB 5V DC input and steel needle emitters gives you an ion-generation component for air-purifier applications. Choose between two generator types: Negative Ion for negative-ion output, or Plasma for both positive and negative ions. Both options have a black housing and attached emitter heads.
The Negative Ion option uses a multistage circuit to convert DC input into negative high voltage, generating negative oxygen ions through corona discharge. The Plasma option produces positive and negative high voltages to ionize air. This difference lets you select the ion generator by its output type rather than treating the two options as interchangeable.
For an air-purifier project, match your chosen module to the electrical and installation requirements of your equipment. The Micro USB connection accepts DC 5V input; the emitter side operates at high voltage. Choose the negative ion generator module for negative-only output, or select Plasma when your application calls for a positive and negative ion generator.

What problem does it solve?
It supplies the ion-generation component for an air-purifier project, helping you choose the required output without buying a different type of appliance. If your setup calls for a negative ionizer, select Negative Ion. For an application requiring both polarities, choose Plasma. The two options make that electrical distinction clear before you start planning the installation.
The problem in numbers
A US exposure study found levels of about a dozen common organic pollutants were 2 to 5 times higher inside homes than outside. (US Environmental Protection Agency, TEAM Study, 1985)
An estimated 8.9% of US adults had current asthma. (Centers for Disease Control and Prevention, National Health Interview Survey, 2023)
An estimated 4.8 million US children had current asthma. (Centers for Disease Control and Prevention, National Health Interview Survey, 2023)
Indoor air quality deserves careful equipment choices, but these figures do not establish a benefit from this module. It supplies ion generation for compatible equipment, not a demonstrated treatment for asthma or removal method for gaseous pollutants.
Why choose this one?
Choose this one for its Micro USB DC input, steel needle emitter heads and choice of ion output. The usb ion generator accepts 5V DC at its input, while the internal circuit produces the high voltage used at the emitters. Its black housing and attached emitter holders provide a defined module format for your air-purifier application.
What exactly do you get?
Choose one generator type for your order: Negative Ion or Plasma. The selected module has a black housing with attached steel needle emitters. Negative Ion produces negative ions only; Plasma produces positive and negative ions. Select the option that matches the output your equipment requires, using the Micro USB DC 5V connection for input power.
Frequently asked questions
Straight answers about the materials, care and everyday use — no fine print.
Is this a complete air purifier or a component?
This is a component for air-purifier applications. The negative ion generator provides ion generation through attached emitters, making it a negative ionizer module rather than a complete room appliance.
What is the difference between Negative Ion and Plasma?
Negative Ion produces negative ions only, while Plasma produces positive and negative ions. Choose the negative ion generator option when your application requires a negative ionizer, or Plasma when it requires both polarities.
What power input does it use?
The module accepts DC 5V through a Micro USB connection. This negative ion generator uses that DC input to operate its internal high-voltage circuit, so match the ion generator to a compatible electrical setup.
How does the Negative Ion option generate ions?
It converts DC input into negative high voltage through a multistage circuit. The negative ion generator uses corona discharge to generate negative oxygen ions, which is the operating principle of this negative ionizer.
What are the emitter heads made from?
The emitter heads use steel needles. Both the negative ion generator and Plasma ion generator options have attached emitters with black holders.
What color is the module?
The housing and emitter holders are black. Select your negative ion generator by the required output type; the ion generator options are named Negative Ion and Plasma.
What is the output voltage of the Negative Ion option?
The Negative Ion option has an output specification of −5500V ±500V. This negative ion generator has a DC 5V input, but its negative ionizer circuit produces high voltage at the emitter side.
What is the output voltage of the Plasma option?
The Plasma option has a printed output specification of ±5000V ±500V. Unlike the negative ion generator option, this ion generator produces both positive and negative ions.
Which option should I select for negative-only output?
Select Negative Ion for negative-only output. That negative ion generator is the appropriate negative ionizer option when your application does not call for positive-ion output.
Does choosing Plasma mean I receive both generator types?
No, Plasma is a separate generator-type selection, not a combination of both options. Choose either the negative ion generator or the Plasma ion generator to match the output your project requires.
