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.

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.

Tips & Warnings
Build the ionizer in a clean, debris-free space with plenty of room for working and preparing the various components of the ionizer. The best environment is a dedicated workshop with workbenches and easy access to tools.
Build your own air ionizer only if you have specific training in the field of electrical engineering or electronics. The process is complicated and the danger of being electrocuted is always present. You will be exposed to high voltage during the process of building your own ionizer, so take appropriate measures to safeguard yourself against electrical charges.
