The Air-Zone® XT-120 has 25 times the ozone output of many popular ionizers.

Why is that important? Ionizers do not have the ability to perform unoccupied room High Ozone Shock Treatments that are a MUST to kill bacteria, and mold.

We know from scientific tests that bacteria, mold and viruses can ONLY be killed if a certain level of ozone is reached and maintained for a certain period of time.

For example e-coli bacteria needs a sustained ozone level of average ozone level 0.28 ppm. for a period of two hours. Of course this level of ozone is too high to breathe, that's why to truly kill bacteria and mold ozone must be blasted into unoccupied rooms. 

Most ionizers do not have the ability to perform a High Ozone Shock Treatment that can achieve the Penn State specified ozone level 0.28 ppm. for 120 minutes.

Exposure of E. coli to low levels of airborne ozone (0.1-0.5 ppm).  Average ozone level 0.28 ppm.   Temperature 75 degrees, 22% relative humidity,  Test performed by Penn State Biology Dept.; W. Kowalski, Brad Striebig,  T. Whittam, W. Bahnfleth.

CFU = Colony Forming Units

Ionizer manufacturers claim that their ionizer only put out a "safe" amount of ozone of 0.02 ppm (parts per million) to 0.04 ppm (max). 
Read that very carefully, that's what they claim their ionizer PUTS OUT.

If it has been scientifically proven that higher levels of ozone are needed to kill bacteria how can an ionizer hope to kill this bacteria? Of course to kill all the bacteria in a room that would mean that the the ENTIRE ROOM would have to be filled with a specific level of ozone (0.1-0.5 ppm). 

If their units are only putting out low levels of ozone at their output vents how can they even hope to achieve a higher ozone level five or ten feet away from the unit?

The fact of the matter is that these units would seem to not be able to kill very much bacteria at all. That's not us stating this, that simply the conclusion made by independent tests like the Penn State University test.

If an ozone generator was placed in the center of a room 20 feet by 20 feet (400 sq.ft.) that only put out 0.1 ppm at it's output vents, there would never be more than a 0.00125ppm of increase of ozone measured anywhere in this sized room except DIRECTLY IN FRONT of the units output vents!!!

Ozone breaks down within 30 minutes. There would be NO chance for the ambient ozone level in a room to increase since a 5 mg.hr. production cannot raise the ozone level a significant amount because of ozone's natural decay.

In other words no matter how long a 5 mg.hr. unit was run, it could never catch up and increase the ozone level more than 0.00125ppm!

Claiming a unit that only puts out 5 mg.hr. can purify the air in a 500 square feet area has NO basis in scientific fact, according to tests like the Penn State test.

The extremely low concentration of ozone as produced by most ionizers would seem to perform NO air purification by ozone at all, according to tests like the Penn State test.

Why is a high ozone output so important?

Ozone naturally decays back to oxygen in about 30 minutes.

Ozone levels below 0.01PPM cannot kill bacteria

With a true high powered ozone generator you can blast out unoccupied rooms to kill bacteria and mold.

That is not possible with an under powered unit since they can never develop a high enough concentration of ozone.

The Air-Zone® XT-120 ozone Generator outputs 20 ppm of ozone at its output vents when set on maximum output.

The great thing about Air-Zone® Ozone Generators is that they have the ability to put out high levels of ozone needed for unoccupied room High Ozone Shock Treatments, AND the ability, by use of their "burst timer" to put out "safe" levels of ozone meant for air purification as well. 

What's Wrong With Ionizers?

Ion Generators simply negatively charge the air's ions so that floating dust particles will cling to a surface in the room, much in the way static electricity does. 

Larger particles of dust floating in the room will stick to the wall, floor, and furnishings of any room they are in. 

There are a few problems associated with ionizers. To perform air cleaning, meaning removing larger particles of dust, you need a very large amount of ions. More than has been recognized as a safe level.  According to air science,  indoor air has 100 to 200 ions per cubic cm, outdoor fresh air has 200 to 500 ions per cubic cm,  and a fresh clean forest will have 1,500 to 5,000 ions per cubic cm. 

Ion generators typically produce more than 1,000,000 to 10,000,000 per cubic cm. This is simply too much. This large amount of ions are needed to push the particles to the walls and floor. In fact for ionization to be truly effective, ionizers must generate so many ions that they can possibly cause headaches and sore throats.

The problem with this is that the same dust can be kicked right back into the air. The dirt that does not begin to float again will stick to whatever surface is close. After a few months walls, floors, appliances, and furniture begin to build up a layer of dirt on them. If you put an ionizer on a table near a wall, the wall will develop a black halo of dirt in just a couple of days.

Some ionizers claim to have plates that collect the dirt.
In truth they can only collect less than 5% of the dirt. The other 95% of the dust, bacteria, and mold spores end up on your walls, floors, and belongings. 

How is an ion that is shot across a room, attaching itself to a dust particle, supposed to travel all the way back to a dust collection plate on an ionizer from 10-20 feet away? 

The answer is it cannot be done. In fact if the ion does travel across the room, the particle it attaches itself to will adhere to the closest possible positively charged surface, that being your walls, floor, ceiling or anything else it is close to. This is not rocket science, it is simple physics. 

Even ionizers that draw air through them and collect dust as it is passing by are not efficient for capturing dust.  They are still emitting ions far into the air in front of the machine. 
These ions then attach themselves to dust particles. If the ion flow, or the airflow of the ionizer is strong the dust will never be able to find it's way back to the ionizers collection plate. 

The dust will then, of course, attach itself to ANY positively charged surface in your home. 

If the ionizer is weak it will do hardly any good at all at capturing dust particles. If it has a strong ionic or airflow then the ions will break away from the machine and cause the dust to be collected on the surfaces of your home. 

This nonsense that ions will simply "drop the dust out of the air" to be vacuumed up at a later time is simply not true. Simple physics state that the dust MUST adhere to the closest positively charged surface, most likely your walls and furniture.

Ionizers will cause the dreaded "black wall effect" where they will turn your walls black with dust. Air-Zone® Ozone Generators will not cause your walls to turn black like common ionizers will because our machines only produce very small amounts of ionization.

Six months after you start using an ionizer you will have MORE bacteria collected in your home than before you started! 

Realize that all so called "air cleaning" ionizers do is limited to pushing around lightweight particles of dust. They cannot effectively kill odors, nor can they remove large particles such as pet dander. 
 

For removing larger particles of dust and dander a HEPA filter is much more effective than an ionizer. HEPA filters collect the dust and dander rather than just pushing around the room as an ionizer does, so that it does not start  floating around again.  The idea is to remove the dust from your home, not simply move it from here to there. Air-Zone® sells quality, hospital grade Austin Air HEPA filters that are more cost effective than store bought brands. Please CLICK HERE to view them.

If dust and odors are present, a combination of an ozone generator and a HEPA filter is the best method of dealing with the problem.

A room that has had a previous High Ozone Shock Treatment will smell much fresher than a room with an ionizer currently running.

Yes, all of our ozone generators produce negative ions, but not as much as compared to a
standard ionizer. Most ionizer products output more than 1,000,000 to 10,000,000 per cubic
cm. This is way too much. More is not always better.
Too much ionization can cause headaches and sore throats.
Too much ionization electronically glues bacteria, mold spores, and particulate matter to your walls, floor and ceiling. 

According to science, outdoor fresh air has 200 to 500 ions per cubic cm, indoor air has
100 to 200 per cubic cm and the forest will have 1,500 to 5,000 ions per cubic cm.

Our ozone generators produce negative ions of about 10,000 to 30,000 per cubic cm. Therefore, the amount of negative ions output from our series of products is good enough for giving indoor air that fresh clean smell, and yet not too much as to be irritating.

What is the difference between air cleaning and air purifying?

Air cleaning means that particles of dust and other dirt are being filtered out of the air, and are hopefully being collected into a specific filter. 
Air Purifying means that dangerous mold spores, bacteria, and viruses are actually being killed. 
That's what an ozone generator can do.
Even a high grade HEPA filter can store, and pass micro bacteria through it. 

Air Purifying is the only way to ensure a safer environment. Air Purifying can only be done by the use of ozone.  Ion generators simply move particles to other places.  That's NOT air cleaning because the dust remains in the same room.

Ionizers also produce a very small amount of ozone which can contribute to a fresh spring like smell. The electrically charged air produced from an ionizer can smell very fresh.
The problem is that it is only a temporary fix. As soon as the ionizer is turned off the effect is essentially over. With an ozone generator odors can literally be killed so that when it is turned off the odors are vanished not simply being "covered up".

Ozone Generators can also be used to give high ozone "shock treatments" to unoccupied areas. These high ozone treatments are very effective in killing odor producing organisms.
Once the organisms are killed by a high ozone shock treatment, or a series of shock treatments,
the odor will be removed, not just covered up by the temporary effects of ionization.

Even with a very high ion level of 10,000,000 per cubic cm, odors can only be covered up. Therefore a high concentration ion treatment will have little or no effect in permanently removing odors. Those high ion levels can also cause headaches and sore throats. So way before ionization can have any real effect it becomes obnoxious.

Absolutely not! Ionizers don't kill any organisms, therefore they will have no effect on mold or mold odors. If you smell mold in your home, you have mold. 
Mold medical studies have found that mold & mildew are the #1 causes of allergic symptoms.
The Black Mold Stachybotrys found in homes, offices, and schools has been linked to fatal pulmonary disorders.

Why are ionizers so popular?

The answer is two fold;

At first, when a person first smells the odor coming out of an ionizer, they are very impressed by the fresh spring like smell of the air coming out of it.  That fresh smell is what sells the product. 

Unfortunately that fresh smell is only temporary, since it lasts only until the ionizer is turned off. 
Ions have no ability to kill any organisms, and therefore no odors. 
On the other hand, ozone kills the bacteria and mold, so it removes the odor, it doesn't just cover it up. 

Secondly, ionizers are very popular because they are very cheap to build, and sell for high dollar amounts. 
The leading manufacturer of ionizers sell their product on TV (you know the ones we mean).
They sell them for $350.00 or more, yet this product costs them about $35.00 to produce. 

We know the cost to build these products because we are equipment manufacturers ourselves.

Manufacturers make huge profits on ionizers, sometimes over 1000%, so they have no interest in ceasing to sell them. They are an easy "sell" because of the fresh smell to the unknowing consumer.

If we wanted to sell ionizers for outrageous profits we could.  They are not hard to build.
We choose not to sell ionizers because we know not only do they not work, they make bacterial problems worse. They do so by electronically gluing bacteria, mold spores, and dust to your walls, floor, and ceiling.

Ozone actually kills bacteria, mold spores, and viruses, by destroying them, and leaving only harmless oxygen remaining.

By testing mold spore counts before and after ozonation, by the use of a mold testing kit, we can prove ozone can kill mold and bacteria.

Ionization subjected to the same tests, no matter how powerful, has any effect on the mold whatsoever.

What is the Ionizer Black Wall Effect?

Ionizers cause the dreaded "black wall effect" where they will turn your walls black with dust. 

Some ionizer manufacturers claim that their ionizers will not cause the ionizer black wall effect.

This is simply not true.  If a machine is a true ionizer then the dust particles the ions come in contact to must, by the laws of physics, adhere to the nearest positively charged surface.
That is usually your walls floor and ceiling.

Some say the dust merely drops to the floor to be vacuumed up later.  Once again that is what they would like you to believe, but is simply not true.  Besides the dust would still be in your home and not "removed" as most ionizer manufacturers claim.

Air-Zone® Ozone Generators will not cause your walls to turn black like common ionizers will because our machines only produce very small amounts of ionization.

What about combination HEPA, ion, ozone, UV purifiers?

Even those fancy, expensive, new units that use special destruction chambers to kill bacteria can ONLY kill what air is drawn into them, not ALL the bacteria in the air, or that exists in the entire room, like a true, unoccupied room High Ozone Shock Treatment performed with a high powered ozone generator can.
They are not safer, because they are not getting the job done.

First off, as proven above, they have such low ozone outputs of only 50 mg.hr. as to be effective in truly killing mold and bacteria. That low level is not enough to fill an entire room to perform effective  High Ozone Shock Treatments.

That fact can be proven on our Ozone Bacterial and Mold Killing Studies Page.

Secondly why would someone need an ion generator if they had a good HEPA filter to collect dust like the Austin Air HEPA Filters we sell? 

It would seem to us the ions would work against the proper collection of dust due to the many reasons described above.

The low cubic feet per minute airflow of the  Surround Air XJ-3000C HEPA is only 71cfm compared to  our medical grade Austin Air HEPA Filters that have a 400cfm airflow.

Austin Air HEPA Filters have more than 5.6 times the air flow than the Surround Air XJ-3000C HEPA.

If you don't have a high enough CFM rating you can't pull as much dust and dirt into the filter, and effectively filter the air of dust and particulate matter.

A HEPA filter is only as effective as it's CFM rating.

The Austin Healthmate Jr. also uses 6.5 pounds of activated carbon in it's filter. The Surround Air XJ-3000C HEPA doesn't list how much carbon material is in it's filter.
Does it even have a pounds worth, or just a few ounces of carbon in it?  Surround Air does not say.
 

The 5 year warranty on the actual HEPA filter in our Austin Air machines is more than double of most other brands. Having to change the main filter once, twice or three times a year is expensive and messy.

That's why you see Austin Air HEPA Filters in most hospitals, and not the cheaper brands sold in stores.
Their high airflow rate, quiet, efficient  operation, and the 5 year warranty is what makes Austin Air HEPA Filters the best HEPA filters in the world.

After a years time it is evident that a true hospital grade Austin Air HEPA Filters actually costs less thank the cheaper, less effective, store bought models.

Finally it is important to note that General Electric, the leading manufacturer of UV bulbs state on their website that their bulbs cannot kill mold once it has formed.
