Biozone claims to remove allergens and pet dander.  We know that HEPA filters remove dust, pollen, and pet dander. They do so by collecting them in the filter so that they can be collected and removed from the home.

If Biozone units are claiming to "remove" this type of particulate matter, we would like to ask: 
Where do the allergens go? The term remove means to take away. Take away from the air?
But that would mean they are still in the room.  So what do they mean when they state their machines "remove" allergens.

We believe that ionizers do not "remove" dust and particulate matter from a room, they simply move them around the room.

This could be true if they use enough ozone.  However here the key is to use enough ozone. 
All bacteria, viruses, and mold can be killed by certain levels of ozone. 

Since Biozone will not reveal the ozone output of their air purifiers how can we know how powerful they truly are? One would think if they had a substantial ozone output they would be glad to state their ozone output in the industry standard measurements, like we use, of milligrams per hour output of ozone.

The fact they state they only put out a "safe" amount of ozone. 
What does that mean and how can we possibly compare it to another ozone generator unless they list the amount of ozone their units put out?
They claim it is no higher than 20 mg.hr in their largest units. That's not very much, certainly not enough to kill all the bacteria in a room.

We show that our Air-Zone® units will will kill mold and bacteria.
These studies can be seen on our Ozone Bacterial and Mold Killing Studies web page.
It is very important to note that specific levels of ozone must be maintained in a room, for specified periods of time in order to effectively kill bacteria.

For example, e-Coli bacteria can be killed by ozone ONLY IF the ozone ppm level remains at 0.28ppm for a period of 120 minutes. That was documented HERE by Penn State University.

There are a couple of points to be made here.

First that level of ozone must cover the ENTIRE room. A 0.28ppm ozone level coming out of a front of a machine will not be nearly at that level 5 feet from the machine.

Secondly the highest level of ozone that a person is recommended to be in the room with is 0.05ppm. That is considered the maximum "safe" level of ozone.

So it would seem that, according to the Penn State University test e-Coli bacteria can be effectively killed by ozone if a higher that accepted level of ozone was maintained in a room for at least two hours time.

That is why Air-Zone Ozone Generators have the ability to perform High Ozone Shock Treatments in unoccupied rooms. 
That is precisely why our units have the ability to be turned up to ozone levels far above those which are considered "safe".  But our units also have the ability to be turned down to "safe" occupied room levels of ozone because of their built in burst timer.

In conclusion if an ozone generator cannot ever rise above air purification levels of ozone, it would seem to us, according to prominent university tests that bacteria could not be killed.

What About Ionization?

We feel that ionization does nothing but move bacteria and dust around your room, turn your walls black, and doesn't kill bacteria. We have never seen a valid test to prove otherwise.
In fact since ionization only moves bacteria around the room over time it actually increases the bacteria and mold count!
For more on ionization please read our page: Why Ionization Doesn't Work For Air Purification.

Ionization, even very high levels of ionization cannot effectively kill bacteria, mold, or viruses.
Now some manufactures may claim to have tests stating that it does but be very careful to understand what facts you are actually reading.  Anyone can commission a laboratory test .

Does that mean that any lab test is always true? Of course not. That's why we rely on independent lab testing. The type done by prominent universities, and the US government.

They state "When a strong enough ultraviolet light is present, it becomes useful in the destruction of contaminating organic compounds. Almost all indoor contaminants are organic, such as toxic volatile organic compounds, dust particles like dander, hair, dust mite feces, etc."

The destruction of dust particles by ultraviolet light? 
That must be one VERY strong ultraviolet light.
Notice they they never say that their machines can achieve this level of ultraviolet light, only that a "strong enough" light will. What is that level of light?  It must be able to be quantified.
What about what General Electric states about ultraviolet light on their web site:

As shown in the diagram above, simple Oxygen molecules known as O2, can be turned into Ozone, O3, by the introduction of the high voltage electrical charge given by an Air-Zone Ozone Generator.

Ozone is considered an unstable gas, meaning it cannot exist for more than a very short time.

Very soon after it is formed, nature forces the third oxygen atom of Ozone to break free, and oxidize bacteria, viruses and pollutants.

Bacteria, viruses, and mold are all destroyed by this process.

All that remains after reactions with ozone are the harmless compounds of pure oxygen (O2), carbon dioxide (CO2), and hydrogen (H2). 

The introduction of low levels of ozone leads to cleaner air to breathe.

At low levels ozone is perfectly harmless and safe to breathe. At higher levels ozone can be used to completely sterilize unoccupied areas infected with large amounts of bacteria and mold.

Air-Zone Ozone Generators have the ability to produce both very low safe levels of ozone needed to purify air, and they also can produce the very high levels of ozone necessary to sanitize highly infected areas when they are unoccupied. 

Most ozone generators either produce too little ozone to be effective, or too much as to be unable to be used in rooms where people are present.

Air-Zone Ozone Generators avoid these problems, and have the unique ability to be used in either type of situation.

Ozone at low levels has a fresh, sweet, after a rain storm type odor.
This is the level recommended for air purification.

At higher levels ozone will begin to have a chlorine bleach type smell. 
When to air begins to smell like bleach it means that the ozone level is set to high for air purification, and should be set at a lower ozone setting. 

This is very easy to do with Air-Zone® Ozone Generators because of the built in burst timer included with the unit. 
Most powerful ozone machines cannot be set to these low levels of ozone.

If an ozone generator cannot reach the high levels of ozone needed to sanitize unoccupied rooms that are extremely infected with bacteria, it is considered no more than a mere toy.

Most of the low level ozone generators sold are just that, gimmick items that are considered toys.

Running a low output ozone generator for a longer period of time is never as effective using a more powerful machine.
This is because the ozone is constantly breaking down, and reverting back to simple oxygen. 
 

Ozone naturally reverts back to simple oxygen in about 30 minutes.
Ozone cannot be stored, or made to last for more than a short time.

Small ozone generators can never "catch up" and create the high levels of ozone needed to kill extreme infections of bacteria.

If a room has a bad odor the best idea is to blast it out when no people or animals are present with a High Ozone Shock Treatment before using the ozone generator at the low levels of air purification ozone. 

Your car can reach speeds of 70 miles per hour or more, but that's not the normal speed you drive. 
Yet if your car could never go above 25 miles per hour, you could never take it out on the highway, and it would be considered useless.
