Ivation Ozone Generator Air Purifier, Ionizer & Deodorizer – Purifies Up to 3,500 Sq/Ft – Great for Dust, Pollen, Pets, Smoke & More

There’s no other better unit at purifying and cleaning the air than the one I’m currently reviewing. The Ivation Ozone Generator is the only model that people with allergies swear by. And trust me, I’ve tried and tested many products to know what works and what doesn’t.

So believe me when I say that the IvationAir Purifier is among the most effective generators. The machine releases top quality ozone. And that improves the nature of air you breathe in. In fact, the unit also drives away irritants and dust.

But it’s the exceptional ion technology that gives the product that remarkable edge. The generator utilizes the negative ions as a means to strike the perfect balance. Plus, it covers at least 3500 sq. ft. of space.

In all, the Ivation Ozone Generator Air Purifier consists of clever features. And a durable structure! So you can rely on the product without worrying about these factors.

The primary duty is to filter the surrounding air and eliminate bad odor. Am I right? In that context, nothing beats the way this model works. And the result is pleasant air that you can breathe. Something that people suffering from allergies crave the most!

But no matter what setting you use, the air purifier ends up stinking the entire room. So I would like to list this down as a flaw, although not a deal-breaker.

We Like

10. Green Air Purifiers Green Air Classic Air Purifier Ozone Generator – The Bonus Pick

Green Air Purifiers Green Air Classic Air Purifier Ozone Generator

The Green Air Classic Air Purifier is another invention by JBL Innovative Products. And I decided to list this best ozone generator as the bonus pick. Frankly, I hold the slew of excellent features responsible for my decision.

The washable carbon filter system is the most functional addition. And that’s because what it does is pull in the air to pass it through that carbon filter. And it’s in there that the harmful airborne particles get eliminated. Even if they’re as tiny as point-something microns!

The invaluable filter performs the task of deodorizing unpleasant odors. Then the air travels through the PCO cell where it gets filtered even further. On top of that, the high-performing anion emitters release negative ions. These connect with the dust particles present in the ambient air. And drop them to the ground. So that’s how the Green Air Classic Ozone Generator works!

The machine is apt for removing different kinds of odors. These include cooking, paint, tobacco smoke, and cleaning/chemical agent odors. And the activated oxygen that the generator creates sanitizes pollution. That is present on floors, furniture, carpets, ceilings, walls, and so on. So expect nothing short of outstanding performance in this case.

Let’s talk about some unique features here. They come in the form of the sterilizer and AWAY/Purifier functions. The former gets the UV lamp going for incinerating germs and viruses. And the latter creates ozone depending on the available space in the room.

Since the Green Air Classic Ozone Generator is large and heavyweight, carrying it is not an easy task. Plus, it lacks handles. So it’s quite a shame that the manufacturer failed to include portability into the scene.

We Like

  • ​The ozone output producing capacity is high.
  • It is a well-constructed, economical unit.

We Don't Like

  • Size and weight are not ideal for portability.
  • Power cable is quite short.

Green Air Classic Main Board Install

Best Ozone Generator - Buyer's Guide

The machine serves only a single purpose. And that is to produce ozone, which purifies more than only the air. An ozone generator has the capacity to “ozonate” water and other substances too.

The activated oxygen released by the unit consists of 3 oxygen atoms. These are the most reactive in nature. Especially when they come in contact with other gases found in the surrounding air.

Ozone present in the higher levels of the atmosphere is quite useful. And that’s because it provides protection against sunlight’s ultraviolet rays. But when the same element is a part of indoors or ground level, it causes respiratory problems. And that means it’s harmful, right?

The thing about ozone generators is that they produce activated oxygen (called ozone). And this is something you can use for cleaning the air around you. The machine features internal compressors. And they do an excellent job at processing air to give rise to ozone. Once ozone forms, the generator releases it into the room. And that, in turn, purifies the air.

But what about using the best ozone generator to end mold? Well, the unit also performs the task of killing mold. But that only happens when enough quantities of ozone are produced. And such an action only depends on the size/amount of space being ozonated.

So that’s about it. Time to find out the factors that combine to make up an ozone generator!

Best Ozone Generator: Important Features

1. Mode of Generation

Not every machine creates ozone in one specific manner. The ways of production differ based on the mode of generation. So let’s find out useful information about each mode.

  • Ultraviolet Light Generators

These are also known as VUV, which is vacuum ultraviolet. The generator works exactly like the sun does at producing ozone. It utilizes the light source for providing a narrow UV light band. And this converts the oxygen that comes in contact with it into ozone.

The ultraviolet light generators are not that expensive. But on the downside, they don’t supply a large concentration of ozone.

  • Corona Discharge Generators

This version is the considered to be quite common. What the device does is use corona discharge technology, which comes in the form of a tube. To give rise to the ozone!

And the reason why this mode is more popular is that it relies on ambient air instead of oxygen. That means a corona discharge generator services surrounding air to produce ozone. So the only drawback here is this. The presence of unpredictable changes in weather or environmental conditions! As these control the fluctuations of ambient air!

  • Electrolyte Generators

They operate by breaking water molecules. When you do that, the molecules split into oxygen, hydrogen, and ozone. Since water is the only source material here, these generators don’t depend on the quality of ambient air.

So what’s the problem in this case? The only issue with electrolyte mode is that it demands excessive energy to function.

  • Cold Plasma Generators

Inside this particular unit, pure oxygen comes in contact with plasma. The plasma is produced by the dielectric barrier discharge. And that divides the oxygen molecules. As a result of which atomic oxygen is produced. The atomic oxygen element then relinks in threes so as to form ozone molecules.

So what does that tell you? It means that cold plasma generators tend to create excessive ozone. No wonder they are less common and more expensive!

2. Ozone Production Capacity

The quantity of ozone that you produce is directly proportional to one factor. The level of fresh oxygen the lungs are exposed to. So a higher ozone production capacity means a better relationship between the two.

3. Odor Removal and Mold Elimination

The best ozone generator has the ability to get rid of odor, correct? But does it also offer mold removal and control? There’s no point in buying a machine incapable of performing both the tasks at one go!

4. Size

Portability is a factor that you should always take into consideration. Even if the generator is for household or indoor purposes! Only because you’re purchasing a machine like this doesn’t mean it has to take up most of the available space. Also, the unit should not be a nuisance to transport from one place to another.

The Dangers of Using Ozone Generators

Ozone is safe when present at high levels of the atmosphere. But not so much when found at the ground level. Only then the component is dangerous and unstable.

The process of ozonation is helpful and practical. But only when carried out by an experienced or professional individual! That means an inexperienced person shouldn’t take up the task. Otherwise, he/she is exposing themselves to serious health risks. Because, after all, ozone is nothing but a very powerful oxidant. And that makes it an air pollutant, am I right?

Do you know what happens when ozone and water come in contact with each other? They form hydrogen peroxide. And that’s called bleaching agent. So you get the same outcome when ozone meets the moisture present in our lungs, nose, and eyes.

It can lead to respiratory problems. And even compromise your immune system’s ability to destroy pathogens. Other complications include sneezing, coughing, chest pain, and allergies. These are the most common ozone machine side effects.

Final Word

My Choice: Enerzen Commercial Ozone Generator

Ozone is considered to be a good air purifier only when you know how to operate the generator. This applies even if you’re buying the best ozone generator. Getting a powerful machine is not important. What matters the most is finding an appliance that suits your specific needs.

With that in place, nothing defeats the functionality of the ultimate pick. And that is the Enerzen Commercial Ozone Generator. The ozone production of this thing is 4500mg per hour. It features a large sized fan that sterilizes huge spaces. Plus, the unit is lightweight and compact. And that means nothing but portability.

A larger fan also implies that the generator produces more ozone. And distributes it in a much better manner! This takes care of odor elimination along with mold removal and control. So with the EnerzenGenerator, you have a cost and energy-effective option on your hands.
