Our take on the Negative Ion Generator

A tiny ionizer module that runs on 3.2–3.8VDC and puts out up to -3000VDC, producing a negative ion stream rated above 30 million per cc. It is a bare component, not a finished appliance: it needs a power source and mounting, and it has no fan, filter or sensor. It suits makers and tinkerers who want to add ion output to a small enclosure, a desk device or a pet area. Against plug-in ionizers it is far smaller and cheaper to build with, but it moves no air on its own, so its reach depends on the host device and room airflow.

Pros
  • Very small at 22 x 12 x 4.5 mm and about 2.5 g
  • High rated ion output for its size
  • Low ozone rating, as low as 0.05 ppm
  • Runs on low DC voltage with modest current draw
  • Wide operating range from -25°C to +71°C
  • No filter to replace
Cons
  • Bare module, not a finished plug-in product
  • No fan, so it does not circulate air by itself
  • Needs a 3.2–3.8VDC supply and wiring
  • Ion output and ozone vary with input voltage and load
  • No controls, indicator or housing included

About the Negative Ion Generator

Clean your air with the power of negative ions. The Negative Ion Generator emits up to 20 million negative ions per second to bond with and remove airborne contaminants such as viruses, bacteria and mold spores.

• Compact and portable

• Ideal for home, office or travel

• Place it on a desk, nightstand, kitchen counter or pet area for cleaner, fresher smelling air

• Developed for use on submarines to clean and freshen the air

• Emits up to 20 million negative ions per second

• Negative ions (oxygen atoms charged with an extra electron) bond with positively charged ions such as viruses, bacteria, VOCs, tobacco smoke, dust, pet odors, pet dander, pollen, mold spored and other allergens

• Once bonded, these new, larger particles become heavier than the air and fall to the ground, away from your lungs

• Provides crisp, fresh-smelling air similar to the air near waterfalls, beaches, and mountain springs, where negative ions occur naturally

• Does not produce ozone

• Maintenance-free, filterless operation

• Low power consumption (1.5 Watts)

• Recommended for rooms up to 500 sq. ft.

• Plugs into a USB port or an AC outlet

Questions and answers

What is this, exactly?
It is a small ionizer module, not a complete air purifier. You supply 3.2–3.8VDC and mount it in your own enclosure or device.
Does it need a fan?
It has no fan. Ions reach the room only through air movement around it, so a host device with airflow spreads them further.
How much ozone does it make?
The rating is as low as 0.05 ppm. Ozone output rises with input voltage, so keep the supply within the 3.2–3.8VDC range.
What power supply does it need?
A DC source in the 3.2–3.8V range at about 3 in input current. It does not plug into a wall outlet on its own.
How big a room will it treat?
The module itself has no room rating. Coverage depends on the host device and airflow; treat claims of large-room coverage with caution for a module this size.
Is it safe to handle while running?
The output reaches up to -3000VDC. Keep fingers and metal away from the output while powered, and mount it so the emitter is not exposed.
Where is the Negative Ion Generator cheapest?
At Sharper Image, for $119.99, as of our latest check.
What do buyers say about the Negative Ion Generator?
Rated 5 out of 5 from 9 ratings.
