In 2020, an estimated 3.2 million deaths occurred due to household air pollution.

Contrary to popular belief, outdoor air quality is not the only environmental impurity to human health. Indoor air quality also brings many health risks due to harmful particles in the air. Airborne contaminants include mold spores, airborne viruses, pet dander, and tobacco smoke: which play a major role in air pollution. Hence, it is essential to use air cleaners or air ionizers to remove them and other particles for clean air.

Electronic air cleaners or air ionizers are two common ways to improve indoor air quality. However, the most effective method combines the best of both worlds: air ionization and air purification.

This is where ionic air purifiers come in.

In this article, we will explore how ionizer air purifiers work, their benefits, and respective issues to be aware of.

What is Ionizer Air Purifier?

An ionizer air purifier is a 2-in-one air cleaner that removes harmful airborne particles. Being a perfect blend of an air purifier and an air ionizer, ionic air purifiers use air purification and ionization technologies to provide clean indoor air.

Ionic air purifiers are broadly classified into two categories: fanless or with a fan. Its main function is to remove particles and pollutants in the air. In some cases, ionizer air purifiers can also be integrated into HVAC systems. From commercial to residential use, it is a game changer when it comes to enhancing air quality within a confined area.

How Do Ionic Air Purifiers Work?

Ionizer air purifiers comprise two functions: air purification and ionization. By merging the technologies of two different products, an ionic air purifier does both in a single device. When combined, these ionizer air purifiers are able to circulate air, enhance air flow and purify air simultaneously.

These are the 2 main methods of how they work:


Air ionizers perform by applying the laws of static electricity. By converting and acting as ion generators, they convert neutral particles into anions (positive) and cations (negative). Ionization effectively creates an electrostatic attraction. This allows particles to be magnetically attracted to eliminate harmful pollutants. Like how the mountain air is often fresh, air ionizers work the same way.

There are three different types of ionization technology:

  • Corona Discharge

This technology works as a negative ion generator. It starts by emitting negative ions through a procedure known as a corona discharge. This enables negative air ions to attach themselves to most flat surroundings in the house. Once negative ions attach to these floating small particles, they settle on varied surfaces within the home that is easier to clean.

  • Electrostatic Precipitators (ESPs)

ESPs are slightly dissimilar ion generators. Instead of releasing negatively charged particles, they have positively charged ions in the purifier. The air pollutants land on them by encouraging air flow over precipitation plates. This makes cleaning a breeze as users only focus on wiping the electrostatic collection plates.

These ionizers release positive ions and negative ions into the air. With polarity in their two disparate charges, these small particles attract each other. When bound to each other, these air ions fall to the ground due to their weight. Bipolar ionization makes cleaning hassle-free, as users need only clean the floors.

Apart from being ion generators, they also act as air purifiers. These are some of the key technologies incorporated

Air Purification

Air purifiers work in a much simpler way. Unlike air ionizers, there are no negatively or positively charged ions in the process. Air purifiers rely primarily on a spinning fan and filtration system to do the job. Many air conditioners usually install an air purifier with a strong filtration system to keep the air clean.

Air Purifier

There are three different types of air purification technology:

  • High-Efficiency Particulate Air Filters (HEPA)

HEPA filters are the best air purifiers because they remove over 99.97% of airborne particles, including pet dander, mold spores, viruses, and tobacco smoke. Known as a medical grade HEPA or H13, the filter effectively removes tiny pollutants below 0.3 microns. The best air purifier consists of a 4 step system that removes particles causing lung inflammation.

  • Ozone Generators

Another form of air purification technology is ozone generators sold as air cleaners. An ozone generator is effective due to the high reactivity of ozone. It works by ‘shocking’ the air to achieve clean air quickly. When these ozone-generating air cleaners emit ozone (O3), it reacts with the air to destroy odors.

  • Activated Carbon Filters

This air purifier uses a filtration system with activated carbon filters to improve indoor air quality. Due to the activated carbon and its porous structure, it steadily absorbs volatile organic compounds, odors, and chemicals. Doing so removes these harmful particles from the air, which keeps it clean.

Why Choose Air Ionizer Purifiers?

One of the best reasons for switching to an ionic air purifier is because of its double benefit technology: air purification and ionization. Gone are the days of single-function devices; with ionizer air purifiers, you can kill two birds with one stone. From eliminating odors to harmful particles, the list is endless.

Here are the top 5 advantages of using ionizer air purifiers:

Improve Overall Health

Ionizer air purifiers don’t just purify but also rid the air of airborne particles and pathogens. The negative ions produced combat bacteria in the air by deactivating these microorganisms that are invisible to the naked eye. In addition, ionic air purifiers with a HEPA filter ensure that they keep most airborne particles out. This greatly reduces the risk of infections, asthma attacks, and allergies that arise. In addition, an ionizer air purifier also helps to alleviate allergic reactions due to the invariably clean indoor air.

Cost Effective & Energy Efficient

Unlike an air purifier, ionizer air purifiers use less energy than motorized fans. By releasing negative ions into the air, positively charged particles attach to them, which fall to the surface. Without circulating the air to filter the necessary, a lot of energy is saved in the process. This also helps reduce utility costs incurred, especially for long usage periods. In addition, ionizer air purifiers are generally quieter during operation.

Prevents Mold & Bacteria

The negative ions from ionic air purifiers alter the cellular structure of some microorganisms, including mold spores and bacteria. This disruption can reduce the growth and spread of mold and bacteria effectively. A lower concentration of these microorganisms in the air keeps the air fresh, crisp, and clean. The reduced mold content also creates a healthier environment for sustainable living.

Easy Maintenance

Most do not need constant filter replacements depending on the ionizer air purifier type. The main form of cleaning usually refers to wiping down collection plates to remove the accumulated articles. This can be an incredibly cost and time-effective way to keep indoor air quality high. Almost technical-proof, anyone can open up and conduct the necessary cleaning on the electrostatic plates to keep things running.

Better Coverage

Ionizer air purifiers can cover more areas due to the release of negative ions. An ionic air purifier goes the extra mile compared to a traditional one. The key difference lies in ionized particles that can disperse throughout every nook and cranny of the room. This ensures that pesky pollutants in tricky areas are addressed and eliminated promptly for wonderful indoor air quality.

Are Ionic Air Purifiers Safe?

Air Purifier

The short answer is yes. Ozone is created when there is an excessive amount of negative ions and positively charged ones released by an ionic air purifier. According to the ČSN EN 60335-2-65 ED.2 regulation, the permitted amount of 0.05 ppm is akin to ozone accumulated from a walk in the park. Despite the fact that ionizer air purifiers produce harmful ozone, it is a tiny amount that is within regulatory compliance.

As the environmental protection agency instructed, the ozone levels needed to eliminate odors and pollutants are generally insignificant. A pro tip is to avoid selecting designated ozone generators occasionally found in commercial air purifiers. This ensures that the ozone produced is not a lung irritant, as they are responsible for excessive ozone emissions.

In Summary

As technology advances, it is inevitable that air quality changes. The only way to combat this is to be proactive and take charge of your health. Staying healthy can be as simple as getting the right tools to begin.

One of the best ways to start is by eradicating harmful particles in the air you breathe today. With an ionizer air purifier, you can take better care of your body the right way.
