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.

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