The Problems With UV Ultraviolet Air Purifiers

We don't use ultraviolet lamps in our air purifiers or ozone generators.
There are some serious problems with UV, Ultraviolet air purifiers.

First off UV light is only going to kill bacteria that it can "see" and come in contact with.
If the bacteria does not pass in view of the light it's not going to be killed.
So if a UV air purifier does not use a fan, or a very slow moving fan, there is very little chance the light will be able to "see" and kill the bacteria in a room.
It can ONLY kill the bacteria it can come in contact with.

Since ozone is in a gaseous state it can flow all around us and it can come in contact with much more bacteria than UV light ever could.

Another problem is that while UV light can kill bacteria, most UV air purifiers use such a low level of ultraviolet light that they cannot be effective. 
 

While UV Ultraviolet in duct air purifiers are now popular, their ozone output is very, very low.
Typically only 25 - 100 mg/hr or less. 

UV ultraviolet lamps are also ineffective in killing mold and bacteria.
This is a direct quote from General Electric, the manufacturer, concerning their germicidal UV lamps.  "Once mold has already formed, ultraviolet energy will NOT eliminate it."

Here is a chart that displays the levels of UV needed to kill bacteria and mold.  Note that the levels to kill mold are much, much higher than to kill even simple E coli bacteria.

The highest ozone concentration that can be produced by 185-nm UV lamp is .2 percent by weight, approximately 10% of the average concentration available by corona discharge ozone.
These levels of ultraviolet light needed to kill mold and bacteria are hundreds, even thousands of more powerful than any UV air purifier made today.
In other words, you're never going to find a UV air purifier that comes close to the needed UV energy levels to kill mold and bacteria.

To the contrary, our high out put ozone generators can produce the very high levels of ozone needed to kill bacteria and mold. This is done by blasting High Ozone Shock Treatments into unoccupied rooms.

Most ultraviolet ozone generators have no ability to perform High Ozone Shock Treatments.

Many of our ozone generators have the ability to purify the air AND to give unoccupied areas High Ozone Shock Treatments needed to truly kill mold and bacteria.

Read more about ozone, and the levels it needs to kill bacteria, on our Ozone Bacterial and
Mold Killing Studies page.

MISCONCEPTION:

Some ozone sellers now claim that UV ozone generators are better because they are unaffected by humidity. They erroneously claim that a 550 mg/hr UV machine puts out as much ozone as a 1100 mg/hr machine.
That type of claim is nothing less than ridiculous. 
That's like someone trying to convince you a $100 dollar bill is worth $200. 
Their 550 mg/hr ozone machine is JUST that, a 550 mg/hr ozone machine! 
A 550 mg/hr ozone generator is just that, a 550 mg/hr ozone generator. It is NOT a 1100 mg/hr ozone generator. The MAXIMUM amount a a 550 mg/hr ozone generator will EVER put out, of course, is 550 mg/hr.

The competitions 4000 mg/hr UV ozone generator will put out 4000 mg/hr, not the 10,000 mg/hr that they say it is equivalent to. It will NEVER put out more than 4000 mg/hr of ozone.

Claiming a 4000 mg/hr ozone generator is equivalent to a 10,000 mg/hr ozone machine is not just an insult to our intelligence, it is an out and out lie.

Also note that UV ozone generators loose about 20% of their ozone power after the first few hours of operation.

ALL Our Ozone outputs are rated in HIGH HUMIDITY environments.

Our 6000 mg/hr ozone generator puts out 6000 mg/hr even in high humidity environments.
In fact at lower humidity environments it's ozone output can top 6500 mg/hr.

Air-Zone ozone generators do NOT use ultraviolet bulbs like many other ozone machines use. That is because our United States patented ozone element is far more powerful than any UV bulb made in terms of actual ozone output..

Our ozone elements are literally HUNDREDS of times more powerful than ultraviolet bulbs.

Why don't we use ultraviolet lamps?
Because they are ineffective in killing mold and germs.

This is a direct quote from General Electric, the manufacturer of germicidal UV lamps.

"Once mold has already formed, ultraviolet energy will NOT eliminate it."

Our United States patented ozone elements CAN produce ozone levels that can kill mold!


 

The problems with UV Ultraviolet in duct air purifiers.

To start with, corona discharge ozone generators are many times more powerful than UV lamps.
Some corona units, like ours, are actually hundreds of times more powerful than the most powerful ultraviolet lamps.

While some may think that a UV Lamp used in a duct will treat ALL the air passing by it, this is simply not so.

UV light is only going to kill bacteria that it can "see" and come in contact with. 
This presents serious problems in a UV in duct air purifier.

In fact, just 2 inches from the surface of the glass of a UV lamp, the UV efficiency drops more than 80%.
The decline in ultraviolet energy then continues to drop exponentially the further away from the lamp that it is measured.

Since the air is going to be passing by the UV purifier at a high rate of speed in the ducts, it will have very little time to be "seen" by the ultraviolet light. The limited contact time the ultraviolet energy has with the bacteria means that very little of the bacteria will actually be killed by the light.

In plain language that means since the bacteria will be flying by so quickly in a duct, it will have very little chance of being killed. It's exposure to the ultraviolet energy will be extremely limited.

One might think of the analogy of waving your hand over a candle. If you were to move your hand quickly through the flame, you would barely feel the heat. But if you moved your hand slowly through the flame, you would be burned. 
The fast moving bacteria in a duct will simply not have enough exposure time to the UV light to be killed.

Furthermore five feet down the duct, or around the first bend, the UV light can no longer be "seen" by the bacteria, so that NONE of that already existing bacteria living in the duct will be killed.
Nor will any of the bacteria be killed that is in the room the duct feeds into, once again because the UV light itself will never reach that room.

This is not a problem with a corona discharge, in duct, ozone generator like our Air-Duct 2000.

With our Air-Duct 2000 unit, the ozone will be fired directly into the ductwork killing mold and bacteria all throughout the duct. The ozone will come in contact with all of the bacteria and mold living in the duct and help to kill it.  NOT just the portion of the duct that the UV light will be able to "see".

The ozone generated by the Air-Duct 2000 will be spread throughout the entire home, thereby purifying air, and killing bacteria in all the rooms. 

UV light must be seen by the bacteria to be killed. Ozone is a gas made from oxygen, so that it can be spread far easier and more evenly than a simple UV light source.

Of course some will say that UV light is safer than ozone because it only puts out "safe" levels of ozone.  What is safe about UV light killing only a minute percentage of the bacteria and mold? 

Isn't it a MORE unsafe situation leaving the live bacteria and mold to reproduce in your ductwork?
Wouldn't it be better to kill much more of the mold and bacteria than to leave it behind reproducing in your ducts?

Ultraviolet in duct air purifiers, with their very low levels of ozone, have no ability to perform High Ozone Shock Treatments that are a must for killing mold and bacteria.

The Air-Duct 2000 literally has hundreds of times more output than ANY UV air purifier made.
Yet it has the safety features of the variable ozone level and the "Burst Timer" to limit the ozone needed for air purification levels.

The Air-Duct 2000 is a dual use unit. It can be used for BOTH low level air purification, and high level ozone blasting when the area is unoccupied, to help kill mold and bacteria in the ducts and in the home.

No other UV in duct air purifier made can make this claim. 
In fact most in duct purifiers aren't even adjustable.
That fact alone tells us they are under powered, unable to perform a High Ozone Shock Treatment.

Let's not forget what General Electric, the manufacturer of germicidal UV lamps, states about ultraviolet lamps.

"Once mold has already formed, ultraviolet energy will NOT eliminate it."

The Air-Zone Air Duct 2000
Whole Home - In Duct Ozone Generator

The Air-Zone Air Duct 2000 is the most advanced whole house professional high powered ozone generator ever produced. 

Many of our customers often ask "How do I purify the air in my entire home at once?"

The Air-Duct 2000 is the answer to that question.  The Air-Duct 2000 mounts directly to your forced air HVAC system to distribute ozone to every room of your house.

If your home or business has a heating / air conditioning system that distributes air through vents this unit may be mounted directly to the side of your air duct.

The Air-Duct 2000 only needs 4 inches of clearance inside of the duct to mount which is only about half the space most ultraviolet in duct units need for clearance.

While UV Ultraviolet in duct air purifiers are now popular, their ozone output is very, very low.
Typically only 50 - 100 mg/hr or less. 

UV ultraviolet lamps are ineffective for killing mold and bacteria.

This is a direct quote from General Electric, the manufacturer, concerning their germicidal UV lamps.  "Once mold has already formed, ultraviolet energy will NOT eliminate it."

The Air-Duct 2000 literally has hundreds of times more output than ANY UV air purifier made.

With it's high ozone output of 2000 milligrams per hour it can not only provide an entire home or business with air purification, it also has the ability to shock away strong odors. 

It has a fully variable ozone level control, and burst timer which makes it suitable for homes as small as 1,300 sq.ft.

It also has the power to give an entire home a High Ozone Shock Treatment, or to treat areas as large as 10,000 sq.ft. for air purification purposes.

While purifying the air in your home the Air-Duct 2000 will also be purifying the bacteria and mold that resides in your ductwork.

It features the latest in advanced 21st century technological design.

It's Gold Plated US Patented Xetin II Ozone element are found only in 
Air-Zone Brand Ozone Generators

This very high powered ozone generator is meant for giving low level shock treatments to entire homes designed to kill mold and bacteria, and remove serious odors in unoccupied spaces.

If you are looking for a WHOLE HOUSE air purifier realize that there is
NO tabletop unit, of ANY BRAND that can accomplish this task.
ONLY a unit like the Air-Duct 2000 that fires ozone into the air ducts,
can evenly distribute the ozone throughout the entire home.

The Air-Duct 2000 Induct Air Purifier / Ozone Generator can be used to help remove strong odors and remediate mold spores from an entire home at once. 

Remember the ONLY way to compare ozone generators or air purifiers
is by the output in milligrams per hour.
Square footage ratings by other manufacturers are meaningless
because they do not address the factor of room contamination!
It is the total ozone output in milligrams per hour that counts!

Air-Zone ozone generators help eliminate odors
by attacking them at the source.

The Air-Zone Air Duct 2000 Features:

  • Very strong 2000 mg. hr. total ozone output
  • Variable Ozone with "Burst Control" for small areas
  • Totally automatic operation
  • United States Patented Gold Plated Ozone Elements
  • High Grade Professional Stainless Steel Housing

What makes the Air-Duct 2000 so unique?

The Air-Duct 2000 features a powerful United States, 24 carat gold plated, 2000 mg.hr. corona discharge ozone element.
It is not just a weak UV lamp that most manufacturers use.
It is hundreds of times stronger than ANY UV lamp made.

This second generation United States Patented ozone element doesn't produce any Nitrogen Oxides.

Each element comes apart and can be cleaned in less than a minute. This element will last a least 5 years.

The Air-Duct 2000 does NOT use an ultraviolet bulb as many other whole house ozone machines use. That is because our United States patented corona discharge ozone element is far superior than UV bulbs.

Our ozone elements are literally HUNDREDS of times more powerful than Ultraviolet bulbs.

Why don't we use Ultraviolet lamps?
Because they are ineffective in killing mold and germs.

This is a direct quote from General Electric, the manufacturer of germicidal UV lamps.

"Once mold has already formed, ultraviolet energy will NOT eliminate it."

Our United States patented ozone element CAN kill mold!

Old style ozone "plates" consist of  flimsy easily corroded steel screens and delicate thin pieces of glass or mica which must ALWAYS be in perfect alignment.
If not cleaned and aligned constantly, old style ozone "plates" will produce less ozone, and possibly even spark out dangerous high voltage electricity.

Old style ozone "plates", first designed in the 1800's,  must be removed, scrubbed clean, dried, and be meticulously reassembled, or they will not work correctly. Even with all that work, their life span is notoriously short.


 


 


 
 

Variable Ozone Control with Burst Control

The Air-Duct 2000 in duct ozone generator comes with both a variable ozone level control, and an automatic "Burst Timer" which allows this unit to be used in both small or larger applications.
The variable ozone level control allows the user to vary the ozone level from 1000 to 2000 mg.hr.
The green button, easy to set, burst timer divides the time the unit is producing ozone.  The burst timer can be set to have the ozone produced for 5, 10, 20, 30, or 45 seconds of each minute.
The timer can also be turned off for continuous ozone production.

This means that the Air-Duct 2000 can be set for a total ozone output from between 83 and 2000 mg.hr. That mean it can be used in almost any sized home.

This makes the Air-Duct 2000 the most versatile in duct ozone generator ever produced in terms of ozone output.
The Air-Duct 2000 plugs into any standard 110 volt outlet.


Totally Automatic Operation

The Air-Duct 2000 comes standard with an automatic HUBA air pressure switch.

The HUBA switch senses when there is airflow in the duct. 
When it does, it automatically turns the Air-Duct 2000 on.

It is VERY IMPORTANT that whatever in duct ozonator is used that it have an automatic operation switch. Otherwise the ozone machine will be on all the time and build up a very high level of ozone when the HVAC system is off.

Most in duct ozone generators do NOT have a way to automatically sense if the air handling system is moving air and only produce ozone when the system is on.

If an in duct ozone generator does not have an automatic switch to turn it on and off ONLY when there is airflow in the duct it will build the ozone level to a higher level than is accepted as safe.  When the ducts start to move the air, that very concentrated blast of ozone will reach the occupants and cause them sinus and eye irritation, and most likely a headache.

Any in duct ozone generator, no matter what it's size, MUST have a switch to control it ONLY when air is moving in the ducts.
Otherwise it can be considered potentially dangerous.

Remember the only controversy that exists over air purification levels of ozone concerns the OVERUSE of ozone in an occupied area. 
An in duct ozone generator WITHOUT an automatic switching system, is EXACTLY how the overuse of air purification use of ozone will occur.

The unit can also be run without the automatic HUBA switch if desired.
It can be plugged directly into a controlled outlet of an HVAC system bypassing the HUBA switch.
The Air-Duct 2000 plugs into any standard 110 volt outlet.

Whole House Air Purification

You have may have heard advertisements that some air purifiers will magically "Work through walls"!
That claim, of course, is ridiculous.  Ozone or ions cannot pass through walls. 

But with our Air-Duct 2000 you can distribute ozone throughout your entire home and purify the air directly through the ductwork.  The Air-Duct 2000 is a true induct air purifier.

The simple action of introducing ozone into the duct work will help to kill whatever bacteria may be living in them. The ozone will also help purify the air in your home. Unlike ionizers which cannot kill substantial amounts of bacteria, ozone can truly kill mold and bacteria.

Some people have been known to place popular brands of ionizer/ozone generators near the return air ducts to help purify the air in an entire house. 
That is the absolute WORST possible thing that they could do! 

By introducing ionization into the ductwork it will cause any fine bacteria and mold particles to be electronically glued to the inside of the ductwork. 
That will only INCREASE the bacteria and mold living in an air duct. 

While the ozone from these types of machines may help kill that bacteria, the ionization will have the reverse effect of attaching more mold spores and bacteria to the inside walls of the ducts.
The ionization will negate whatever good that is being done by the ozone.

Read more about the problems with ionization HERE.

Also keep in mind such units typically only put out 360 mg.hr. of ozone. That low level would never have the ability to blast the ducts with a High Ozone Shock Treatment in order to help sterilize the ducts.

With it's high output of 2000 mg.hr. the Air-Duct 2000 can not only purify the air in ducts, it can help sanitize them and kill the mold spores and bacteria that may be living in them as well.

Why is the Air-Duct 2000 better than other
air duct ozone generators?

Most other air duct ozone generators use ultraviolet light to generate ozone. While UV light is capable of generating ozone, it is not nearly as efficient as the patented method of corona discharge ozone that the Air-Duct 2000 produces. 

The Air-Duct 2000 does NOT use an ultraviolet bulb as many other whole house ozone generators use. 
That is because our United States patented ozone element is far superior than UV bulbs. 
Ultraviolet lamps are ineffective in killing mold and germs.  How can we say that?

This is a direct quote from General Electric, the manufacturer, concerning their germicidal UV lamps.  "Once mold has already formed, ultraviolet energy will not eliminate it."

This quote can be read on the web page; Will GE Ultraviolet germicidal lamps kill mold?

The high level of ozone our United States patented ozone elements produce does kill mold!

Most in duct ozone generators also have very low ozone outputs of 300 mg.hr. or less. 
While this is fine for simple air purification, that type of machine would never be able to blast the ducts with a High Ozone Shock Treatments that can kill the mold and bacteria that lives in your ductwork.

Even if you have the best air filter made connected to your ductwork, and you should, they cannot kill whatever mold or bacteria that may live in them.

With it's high output of 2000 mg.hr. the Air-Duct 2000 can not only purify the air in large homes and businesses, it has the ability to blast out the ducts with High Ozone Shock Treatments.
and actually kill some of the mold in the ducts.

That makes the Air-Duct 2000 can a dual feature in duct ozone generator. It has the power to kill mold with High Ozone Shock Treatments, and yet it also can be turned down to a low enough level for simple light air purification.

This is very important because if you have existing odors in your home or ductwork, it is necessary to blast them away before you attempt to use ozone for air purification. 

The higher levels of ozone will help rid permanent odors more effectively than the low air purification levels of ozone.  In that respect you will need less ozone for air purification.

If your in-duct ozone generator has only 400 mg.hr. of ozone output you will be constantly be turning it up to a higher level in order to cover up whatever odors might be present. 

In a very real sense you could be choking yourself out with too much air purification level of ozone when you should have pre treat the area with a higher level of ozone so that you won't need as much ozone for air purification.

In that sense the Air-Duct 2000 is a safer in duct ozone generator because it allows you to pre treat serious bacteria and odor problems with a High Ozone Shock Treatment.
 
 

The Air-Duct 2000 is easy to install onto a forced air, 
or whole house air conditioning system.

The Air-Duct 2000 can be installed by most handy homeowners in a very short time.
The Air-Duct 2000 is can be attached directly to the side of the outgoing airduct of any forced air HVAC system. 

A rectangular sized hole 8.75 inches wide by 4 inches tall is cut on the side of the steel ductwork. The unit is then screwed directly to the side of the duct. 
The Air-Duct 2000 only needs 4 inches clearance inside of the duct to mount.

The automatic HUBA switch is then very simply screwed to the side of the duct. A small hole is then drilled into the side of the duct then air pressure sensor tube of the HUBA switch inserted into the duct. 
Plug the HUBA wire into the side of the Air-Duct 2000, then plug the unit into any standard 110 volt wall outlet. 
Simply adjust the HUBA switch to sense the airflow, and the ozone level to the Air-Duct 2000
The unit can also be run without the automatic HUBA switch if desired.
It can be plugged directly into a controlled outlet of an HVAC system bypassing the HUBA switch.
The Air-Duct 2000 then plugs into any standard 110 volt outlet.

Installation is typically performed in less than 20 - 30 minutes.


Square Footage Ratings

Most other air duct ozone generators list their output by square footage, not by the total output of ozone in milligrams per hour. But what if one company decides 300 mg.hr. will cover 1000 sq.ft. and another company decides that 500 mg.hr. is needed to cover the same 1000 sq. ft.?
That's the way it is in the air purification business, there are few standards which can be agreed upon.

In that sense a square footage rating of an in duct ozone generator is meaningless. 
What is the standard by which they are giving this rating?  How can you truly compare one machine to another if both companies can't agree upon a square footage standard?

That's why comparing the total ozone output in milligrams per hour, mg.hr., is what will truly let you compare one ozone machine to another.

Because there are no standards for square footage ratings for ozone generators, the ONLY number that means ANYTHING for comparison is the actual total ozone output as rated my mg.hr. 

No other standard is viable. Even ppm rating do not tell you the actual ozone output of a machine in the way that a mg.hr. output rating does.

That's not to say that square footage ratings for in duct ozone generators should not be given.
You only want so much ozone in the air that is needed for air purification purposes.  But to compare one ozone generator to another, the only REAL standard is the total ozone output listed in milligrams per hour.

If a company does not provide an ozone output for its machine in mg.hr. there is NO WAY to compare it to another ozone machine. It's that simple.

Square footage ratings for air purification levels of ozone MUST be taken into proper context.

The level of ozone you need to freshen the air in a relatively clean 2000 sq.ft. home, or a home with just one smoker is COMPLETELY different than the level of ozone needed to combat cigarette smoke in the same sized night club with 20, or 30 people in it smoking at the same time. 
That's just common sense.

The contamination level, the number of smokers, or the seriousness of the odor problem MUST be taken into account when deciding how much ozone to use for a certain square footage rating.

This gets back to the original point that a single square footage rating for an in duct ozone generator is COMPLETELY MEANINGLESS!  Because that square footage rating does not address the issue of the overall contamination level. The contamination level in the room MUST be taken into account for a square footage rating to have ANY validity.

When rating one in duct ozone generator, or any type of ozone generator to another the ONLY real criteria MUST be the total output listed in milligrams per hour.

If another brand of in duct ozone generator does not list the total output in milligrams per hour there is NO WAY to compare to another type of in duct ozone machine.

The number 2000 in the name of our in duct ozone generator does not mean it is rated for 2000 square feet like it does for competitors models.

If a competitors model has a number like the In-duct 10000 that does not mean it is a 10,000 mg.hr. unit.  Nor may it mean that is is suitable for 10,000 square feet. The fact is that a number associated to an ozone machine can mean ANYTHING.

The Air-Duct 2000 is named after its true ozone output, 2000 milligrams per hour.  There is no telling what another companies number means in its name.  We know of one company that has a model called the OZ-2000 that only puts out 750 mg/hr of ozone. Be sure and ask a machines true output, don't be fooled.

The Air-Duct 2000 is generally considered to be 4 to 10 times more powerful than many other induct ozone generators.

Be sure to compare ozone generators as apples to apples, not apples to oranges. The total ozone output in milligrams per hour is the ONLY way you can compare any kind of ozone generator to another.
 
 

How does Ozone work?

Air-Zone ozone generators help eliminate odors
by attacking them at the source.

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.

Ozone generators with lower ozone outputs not only take longer to get the job done, they can't do the task as well as the Air-Duct 2000.

Why does the Air-Duct 2000 cost a little more
than other in duct ozone units?

You get a whole lot more with our in duct ozone generator. 
Most in duct ozone purifiers do not even list their output in milligrams per hour.  Because of that there is no way to compare them to our 2000 mg/hr Air-Duct 2000.

Some brands state they only put out a "safe" amount of ozone.  That's a sure sign of an under powered unit.  That means their unit can never perform a High Ozone Shock Treatment.
If they cannot do that their effectiveness is minimal at best. 300 mg/hr is not enough to sanitize the air in an entire home.
Why waste your money on a unit that won't do the job?

The Air-Duct 2000 is made out of a very high grade of thick surgical stainless steel. Most units do not use this grade of costly stainless steel. Most use a cheaper grade of steel that can easily corrode.
Some competitors units are made out of cheap aluminum.
Some are made out of plastic which cannot withstand the heat of a forced air heating system.

Some units use a cheap 12 volt wall transformer to supply the unit with power. The Air-Duct 2000 uses the exact same high quality transformer that is in our professional XT-28000 ozone generator.
A 12 volt transformer is the sign of a cheap unit with low power.

The Air-Duct 2000 is by far the best in duct ozone generator / air purifier on the market. 
Don't settle for less.

The Air-Duct 2000 features these distinct advantages:

The Air-Duct 2000 is made with a United States Patented, 
Gold Plated, 2000 mg/hr Ozone Element. This superior type of element cost more to build than simple, cheap screen and glass ozone elements.

It is also superior to ineffective ultraviolet bulbs. 
Ultraviolet lamps are ineffective in killing mold and germs. 

This is a direct quote from General Electric, the manufacturer, concerning their germicidal UV lamps.  "Once mold has already formed, ultraviolet energy will NOT eliminate it."


The Air-Duct 2000 comes with both a variable ozone level control, and an automatic "Burst Timer" which allows this unit to be used in both small or larger applications.
The variable ozone level control allows the user to vary the ozone level from 1000 to 2000 mg.hr.
The green button, easy to set, burst timer divides the time the unit is producing ozone.  The burst timer can be set to have the ozone produced for 5, 10, 20, 30, or 45 seconds of each minute.
The timer can also be turned off for continuous ozone production.

This means that the Air-Duct 2000 can be set for a total ozone output from between 83 and 2000 mg.hr. That mean it can be used in almost any sized home.

This makes the Air-Duct 2000 the most versatile in duct ozone generator ever produced in terms of ozone output.

The problems with UV Ultraviolet in duct air purifiers.

To start with, corona discharge ozone generators are many times more powerful than UV lamps.
Some corona units, like our Air-Duct 2000 unit, are actually hundreds of times more powerful than the most powerful ultraviolet lamps.

While some may think that a UV Lamp used in a duct will treat ALL the air passing by it, this is simply not so.

UV light is only going to kill bacteria that it can "see" and come in contact with. 
This presents serious problems in a UV in duct air purifier.

In fact, just 2 inches from the surface of the glass of a UV lamp, the UV efficiency drops more than 80%.
The decline in ultraviolet energy then continues to drop exponentially the further away from the lamp that it is measured.

Since the air is going to be passing by the UV purifier at a high rate of speed in the ducts, it will have very little time to be "seen" by the ultraviolet light. The limited contact time the ultraviolet energy has with the bacteria means that very little of the bacteria will actually be killed by the light.

In plain language that means since the bacteria will be flying by so quickly in a duct, it will have very little chance of being killed. It's exposure to the ultraviolet energy will be extremely limited.

One might think of the analogy of waving your hand over a candle. If you were to move your hand quickly through the flame, you would barely feel the heat. But if you moved your hand slowly through the flame, you would be burned. 
The fast moving bacteria in a duct will simply not have enough exposure time to the UV light to be killed.

Furthermore five feet down the duct, or around the first bend, the UV light can no longer be "seen" by the bacteria, so that NONE of that already existing bacteria living in the duct will be killed.
Nor will any of the bacteria be killed that is in the room the duct feeds into, once again because the UV light itself will never reach that room.

This is not a problem with a corona discharge, in duct, ozone generator like our Air-Duct 2000.

With our Air-Duct 2000 unit, the ozone will be fired directly into the ductwork killing mold and bacteria all throughout the duct. The ozone will come in contact with all of the bacteria and mold living in the duct and help to kill it.  NOT just the portion of the duct that the UV light will be able to "see".

The ozone generated by the Air-Duct 2000 will be spread throughout the entire home, thereby purifying air, and killing bacteria in all the rooms. 

UV light must be seen by the bacteria to be killed. Ozone is a gas made from oxygen, so that it can be spread far easier and more evenly than a simple UV light source.

Of course some will say that UV light is safer than ozone because it only puts out "safe" levels of ozone.  What is safe about UV light killing only a minute percentage of the bacteria and mold? 

Isn't it a MORE unsafe situation leaving the live bacteria and mold to reproduce in your ductwork?
Wouldn't it be better to kill much more of the mold and bacteria than to leave it behind reproducing in your ducts?

Ultraviolet in duct air purifiers, with their very low levels of ozone, have no ability to perform High Ozone Shock Treatments that are a must for killing mold and bacteria.

The Air-Duct 2000 literally has hundreds of times more output than ANY UV air purifier made.
Yet it has the safety features of the variable ozone level and the "Burst Timer" to limit the ozone needed for air purification levels.

The Air-Duct 2000 is a dual use unit. It can be used for BOTH low level air purification, and high level ozone blasting when the area is unoccupied, to help kill mold and bacteria in the ducts and in the home.

No other UV in duct air purifier made can make this claim. 
In fact most in duct purifiers aren't even adjustable.
That fact alone tells us they are under powered, unable to perform a High Ozone Shock Treatment.

Let's not forget what General Electric, the manufacturer of germicidal UV lamps, states about ultraviolet lamps.

"Once mold has already formed, ultraviolet energy will NOT eliminate it."

What the Air-Duct 2000 is designed to do. 

The Air-Zone Air-Duct 2000 is designed to freshen entire homes, offices, restaurants or bars of smoke and other odors.
It can purify the air and help remove mold odors. 
It can also be used to lightly shock treat an entire entire home, when it is unoccupied.

This is especially useful in homes where that "funky" odor cannot be located.
Older homes, homes with animal odors, even newer homes with new construction odors can be treated. It can also help kill mold and bacteria that are living in your ducts, and your home.

What the Air-Duct 2000 is NOT designed to do. 

The Air-Zone Air-Duct 2000 is NOT designed remediate or kill mold in entire homes, offices, or restaurants. 

If an entire home has a mold problem that must be totally killed, then this is NOT the type of ozone generator to use. 

For severe mold contamination's rooms must be treated on an individual room by room basis with a higher output ozone generator. For example if a basement has a mold problem then it is is recommended to blast out that area individually with one of our High Powered Ozone Generators shown below.

Because the Air-Duct 2000 will be distributing the ozone through an entire ventilation system, and therefore the entire home, no single room will have a high enough concentration of ozone to be able to kill all of the mold in that room.

It is also NOT designed to cure a severe mold contamination inside of air ducts. 
It can strongly deodorize them , and kill some of the mold in them, but it cannot sanitize entire ventilation systems. 

That takes an ozone generator with a much higher output.  Of course this is all relative to the size and length of the duct work, and the severity of the mold contamination.

The Air-Duct 2000 will help deodorize entire homes of mold odors but it does not have the capability to sanitize the entire home of mold.

On it's high level it will kill some of the mold living in the ducts, far better than most smaller whole house ozone generators because of it's high 2000 milligram per hour output.
 
But because the ozone will be mixed with the normal air that is drawn into the ducts by means of the heating or air conditioning system, it will not have the extremely high concentration that is needed to totally sterilize an air duct of mold.

That is what our high powered ozone generators shown below are designed to do.

Breathing in dried MOLD can cause permanent lung damage.
