What is a Negative Ion Generator (aka. Air Ionizer)? 

Also called an air ionizer or ionic air purifier, a negative ion generator is a device that emits millions of negative ions into the air to remove pollutants from the air. It contains an electrostatic precipitator that uses electricity to generate these ions and blow them into your room.

In return, these negative ions bump and form bonds with small, positive airborne particles like dust, pollen, bacteria, and even pet hair. Consequently, the newly formed heavy particles either fall on the ground or stick to the surface of your furniture.

However, some innovative ionizers come with a combination of a powerful fan and HEPA filters too. These models can remove the ionized and heavy particles from your room.

How Do Negative Air Ions Affect the Human Body?

Although it is a common misapprehension that all types of ions are harmful to your health, this is not the case with negative ions. In contrast to positive ions, there are many benefits of negative ions on your body, both physical and mental.

Some of these effects are listed below to clear out any of your doubts regarding negative ion generators:

  • Negative ions remove dust particles, mold, pet dander, pollen, and many other types of allergens from your surrounding air. As a result, your lungs get protection from inflammation, and your health improves.
  • High-density negative ions can even minimize the concentration of bacteria and viruses in your home.
  • Negative ions act as natural antidepressants by removing debilitating positive particles from the air. 
  • According to research, anions can significantly boost serotonin levels in your body. This improves your mood, energy, focus, reduces insomnia, and offers better sleep quality.
  • Negative ions increase oxygen level and relieve body stress counteracting harmful positive radicals flowing in your blood.
  • They also help to normalize the breathing rate and reduce headaches and blood pressure.

How to Choose the Best Negative Ion Generator?

Since there are various models of negative ion generators available in the market, it can be challenging to find a suitable one for your needs. Which factors do you consider? What model will work best in your room?

Keep reading to find out how to choose the right negative ion generator for your home by considering all the right factors.


Before starting your search for the best ionizer, you should decide whether you require a small, compact one for portability or need a large one for your living room.

There are various ion generators available in the market, from pocket-friendly and car ionizer to huge ones for your whole room. While some are small enough to be plugged into a wall-socket, others may require proper installation and floor space for operation.

Coverage Area

The coverage area of your ionizer is an essential aspect that dictates the overall performance of the device.

Some ionizers emit millions of negative ions in a second and use powerful fans to spread them to the whole room. Meanwhile, smaller models do not use fans and offer a smaller coverage area. 

Whatever your needs, make sure to check for the coverage area before selecting an air ionizer. 


If you want versatility or want to save money on electricity bills, opt for ionizers that come with convenient operation modes. While a few negative ion generators come with timer modes, others might even offer variable speeds or different room options.


The efficiency of an ionizer depends on the negative ions they emit every second. The greater the emission, the better the air quality of your indoor room air.

A higher emission also denotes how far the negative ions will go in your room and even affect your negative ion generator’s coverage area. Hence, it is vital to check if the efficiency of your device is worth its price.

Noise Level

There is no doubt that a noisy machine is highly annoying and irritating. Since you purchased the device to make your life easier, you expect them to work seamlessly in the background.

On a positive note, the majority of air ionizers offer a low-noise operation. This is especially true for all those models that function without a fan.

How to Know If a Negative Ion Generator Is Working?

If your negative ionizer works properly, you will feel a distinct reduction in foul odors from your living space and breathe much better than before. Besides this, you might also notice a thicker dust layer on your floors or furniture, consisting of heavyweight airborne particles. 

Additionally, you can even purchase a chemical test kit or air quality monitor to keep a check on your indoor air quality too.

Are There Any Negative Side Effects to Negative Ions?

There are absolutely no side effects of negative ions on your health. Instead, as mentioned above, they improve your health, immune system, and even your mental well-being.

Does a Negative Ion Generator Produce Ozone?

Although negative ion generators produce some amount of ozone, almost all of them are tested rigorously to keep their amount to less than 0.1 ppm. Hence, these machines are not harmful to both your health and the environment.

Is Negative Ion Generators Safe for Pets?

Like how negative ion generators are safe for your health, they are also entirely safe for your pets.
