Some air purifiers do not have a common True HEPA filter, rather they may use an ionizer to support a physical air filter, or act as the only form of air filtration on their own.

Air ionizer is a device that uses high voltage electricity to generate negative ions and electrically charge air molecules.

In real-world use, the air ionizer is one of the most important air filters used in air purifiers. But are the ionizers good for you? Do air ionizers really work, particularly against smoke, smells and smells? You've read a lot about the air ionizer being bad and harmful, so you need a credible source to buy your air ionizer.

Okay! Okay!

In HealthyBreeze, we know all your problems with indoor air quality and air purifiers. We know you need the best air purifier to improve your quality of life. We're experts in the field of air purifiers, but more than that, we 're just like you, human.

We also have severe issues with respiratory allergies and asthma, and we know that you're struggling to master the air purifier and put an end to your suffering. Today, in our in-depth guide, you'll know all about the air ionizer.

What is an Air Ionizer?

Air ionizer (also known as an ion filter or ion generator) is one of the most common air filters used by air purifiers.

Because of using a fan to drag the toxic air through a physical air filter, the integrated air ionizer uses electricity to release negative ions (or anions) to electrically charge the air molecules. As a consequence, negative ions charge and draw airborne particles either to the surrounding charged collector plate or mechanical air filter, or simply to the nearest walls and ceilings.

Unlike the True HEPA filter, which is capable of handling 99.97 percent of all particles down to 0.3 microns in size, the air ionizer will minimize the size of allergens to as small as 0.1 microns.

Microns, which are one millionth of a meter, are how the particles are weighed. To let you know the size of a micron, we can't visually see anything less than 10 microns. 

Are Ionizers safe to use?

The conclusion is obviously not yes or no.

In short, the air ionizer is only useful for you because it meets the California Air Resources Board (CARB) norm to have an ozone pollution concentration of less than 0.05 parts per million (ppm).

Otherwise, air ionizers may be hazardous to your health. The air ionizer plays an important role in the air purifier industry, as you can maintain the air ionizer without an annual filter replacement and still get the best result of air filtration.

In fact, the ionizer is one of the most effective filtering mechanisms, particularly when combined with a physical HEPA filter. But, as the ionizer purifies the air, it also produces ionized gas, and we people do not usually breathe that kind of gas through our lungs.

In addition, the charged ions can create an amount of ozone that is undesirable. Although the air ionizer is not a type of ozone generator, the amount of ozone from your air ionizer may irritate your asthma or many other breathing problems.

If you don't know, or if you experience the side effect of using an air ionizer, you should disable this ion function as soon as possible.

You should test this California Certified Air Cleaning Devices to help you know the air purifier is certified by the California Air Resources Board (CARB) to be safe to use with or without an air ionizer.

Or else, all you need to do is read our air purifier reviews to see if you can trust one air purifier or not. 

Pros and Cons of Using an Air Ionizer:

We've learned all about the ionizer, but you still don't know if this air filter is flawless or not.

Below are the pros / cons of the ionizer. 


  • Maintenance free, without replacing the filter
  • Good results, some bacteria and viruses can even be removed


  • Small amounts of ozone as a by-product that may irritate asthma and respiratory problems.
  • Does not remove odors and smells
  • Higher energy consumption
