How to Build an Air Ionizer

The air we breathe is filled with airborne contaminants, such as bacteria, pet dander, dust, smoke and odors. Air ionizers work by producing a stream of negative ions that cling to airborne particulates and remove them from the environment. You can build your own ionizer if you want to save some money, but you must know something about electrical engineering or electronics.

Things You'll Need

• Voltage multiplier
• Emitter needles
• High-voltage high-value resistors
• 22 to 30 diodes and capacitors
• Plastic box
• Soldering iron

Instructions

• 1

  Solder the diodes and capacitors together using the existing component leads. You should have the same number of diodes and capacitors, and they should be run in series to create a ladder.

• 2

  Connect the diode and capacitor ladder to the high-voltage high-value resistors. The arrangement of the ladder determines polarity, so ensure that the connections are correct and test for a current.

• 3

  Attach the assembly to the voltage multiplier, which in turn attaches directly to your power source. Integrate a grounding line in your design for the air ionizer.

• 4

  Connect the emitter needles to the resistors, which are necessary to avoid a shock if contact is made with the needles.

• 5

  Power up the device and test the emitter needles for effectiveness. If the device is working properly, you should notice the needles emitting a light stream of air and a quiet hissing. In the dark, you'll notice a light purple-hued corona on the tip of the needles.

• 6

  Place the entire device in a plastic box and seal to protect the components from damage or exposure.
