How To Make A High Voltage Air Purifier Ionizer DIY 15 kvDC 12 v DC Input

Complete step by step instructions on building a powerful air purifier.

This air purifier not only cleans the air but it also keeps y0ur walls, ceiling and furniture clean as well as keeping your lungs clean.

Before you build your air purifier, it is best to review complete information about how they work and what they can do for you.  Click Here

After reading that, you understand that the charged particles that clean the air  cling to anything they touch.  So those  particles build up on your walls, ceiling and furniture. And your  lungs.

In order to prevent this,  you should use a fan to pull the air through an intake collection plate and an exit filter that you can clean or replace. Doing that will keep everything inside the purifier, out of your lungs, and off your walls and furniture.

Steel wool or a steel scrubbing pad works well as an intake collection plate and a vacuum cleaner filter as the exit filter .

So let’s get on with building one.

Materials Required

higj voltage anion generatorAnion Generator – The more powerful the static field created, the more effective it will be.

The one used in this tutorial will develop a static field of -15,000 volts DC (-15kv DC).

Plastic Box – The box that we used in this tutorial is a simple off-the-shelf box with a removable lid.  It measures UUUUU UUUUUUU UUUUUU .

Because we use a common computer cooling fan, the depth of the box should be greater than the width of the cooling fan.








steel scouring padsMetal Mesh –  The mesh will put the charge on the particles.  You should have a piece of screen that will fit inside your box so that all the air passing through the box passes through the the screen.

We use a piece of off the shelf screen available at most building supply stores.





Power Supply – The anion generator and the fan each require a 12v DC power supply. The anion generator is not a transformer and does not draw much current. The fan does draw a continuous current so you should use a wall wart. 1 to 2 amp, 12v DC wall wart is fine.





Female Power Connector – You connect the output of your wall wart to this.






switch without feedbackSwitch – A plastic rocker type switch.  Do not use either a push button or slide switch.  For some reason some of them create a feedback loop that causes the ion generator to burn out.

We recommend strongly that you use one just like this. They are readily available.








compute fanFan – We us a 120 by 120 mm  12 v DC computer fan. There is no problem if you use something smaller.









exit filterExit Filter – This will capture any ions that were not caught by the wire mesh. You will have to occasionally replace this.  How often depends on how efficient your metal mesh is at collecting charged particles.

We use a vacuum cleaner filter.









This short video shows the assembled purifier.

Things that you should note.

1) The inlet holes were made by pressing the point of a hot soldering iron through the plastic.

2) The holes for the power connector and switch were started with the soldering iron and final shaped using a file.

3) negative ion generator wiring diagram This is how the anion generator should be wired.






Connect switch to fan and anion generator

Insert copper wire into wire mesh

Place the  filter on the inside surface of the fan.
