Air-Zone® is currently in the process of obtaining independent test results to provide proof our machines are capable of killing mold and bacteria.

While any company can commission a local lab to perform a test for a few hundred dollars, the question is, are the test results truly credible?

One must make sure that the test results given by various companies have meaning in the real world.

To provide test results that have real meaning Air-Zone® intends to provide results from sources that are independent, and completely credible, unlike many of our competitors.

The tests that have the most credibility are those performed by Universities, the various departments of the US Government,  The Los Alamos National Laboratory, and the non for profit International Ozone Association.

Their test results are never called into question, because they have the reputation of performing the most honest, accurate, scientific tests in the world.

They will never skew test results to fit a manufacturers agenda, because their reputation is at stake with every test they perform.   Click Here to investigate them for yourself.

Air-Zone® has chosen SGS to test our products so that there can be no possible doubt as to their unparalleled accuracy. The tests we have are available upon request. They are numbered, signed, and stamped with the official SGS seal.

You won't see many other manufacturers using test results from SGS, because their products cannot stand the scrutiny of such accurate tests.

We test our own machines for ppm ozone outputs in real world situations, so that the reader will see that Air-Zone® ozone generators can reach the needed levels of ozone concentration needed to kill bacteria and mold. 

Please understand that while certain manufactures show that their ozone generators can produce ozone levels to kill mold, that that is a test measurement of a ppm level of what their machine can output into a petrie dish, NOT the ozone level that must exist in the ENTIRE room.

While some of our tests show what can be killed in petrie dishes also, understand that our machines can also FILL the ENTIRE room with this level of ozone needed to kill the mold and bacteria over a period of time. This is something no low level ozone generator can do.

An ozone generator that can only produce 20 mg.hr. cannot possibly fill the entire room with a high enough level of ozone since that is all it can produce at it's output vents.
Ozone generators that can ONLY produce a "safe" level of ozone in a room are unable in killing mold in an entire room.

The tests of our machines will show that our units will be able to FILL the ENTIRE room with the levels of ozone needed to kill mold and bacteria.

Please always keep in mind that we produce ozone generators than can produce low levels of ozone for air purification, and that some of our models that can perform High Ozone Shock Treatments that are a MUST to kill mold and bacteria blasted into, of course, UNOCCUPIED rooms.

There is a HUGE difference between these two totally different uses of ozone.
Low levels of ozone, as produced by ozone air purifiers, or ionizers will NEVER be able to remediate mold in an entire room. ONLY the use of unoccupied High Ozone Shock Treatments, that our machines can produce will sterilize rooms of mold and bacteria.

Many manufacturers of low level ozone machines claim their units only produce "safe" levels of ozone and misinform the public that these same machines will kill all the mold in their home. This is simply not true.

Keep in mind that while UV Ultraviolet in duct air purifiers are now popular, their ozone output is very, very low.  No matter what bogus studies the people try and show you understand that UV air purifiers cannot kill mold.

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."

Tests have shown that common household bacteria, mold, mildew, and fungus are greatly reduced by the addition of as little as 50 ppb (parts per billion) of ozone in typical household environments.

Pathogens such as, but not limited to, E-Coli, Salmonella Choleraesuis, Staphylococcus Aureua, Candida Albicans, and Aspergillus Niger have been shown to have drastic reductions in population when exposed to ozone, in tests performed by independent laboratories.

Results of E coli exposed to airborne ozone Penn State University March 24, 2000 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  E coli not exposed to ozone  Exposed to ozone 1 hour  Exposed to ozone 2 hours After 3 hours there were no E coli survivors remaining in the petrie dish "Experiments performed by the authors have found that high bacteria death rates can be achieved with airborne ozone. In these experiments, Escherichia coli and Staphylococcus aureus (MRSA) cultures on plates were inserted in a test chamber through which ozone was pumped. The degree of bacterial disinfection and exposure time compared well with the best results achieved in water by other investigators.  The ozonation of bacteria in air should produce even higher death rates of the bacteria because of more uniform exposure of the cell surface to ozone. Ongoing research at Penn State has found airborne concentrations of ozone highly effective at disinfecting surfaces. The levels of ozone capable of producing rapid sterilization appear low enough that natural decay, may be sufficient to render the sterilized air breathable without recourse to ozone filtration. The results presented here demonstrate that high degrees of bacterial sterilization can be achieved with airborne ozone."

This is a test of our older model XT-24000 ozone generator performed by SGS proving that this machine can produce an ozone level high enough to kill 99.5% Bacillus subtilis in just 5 minutes.

The XT-28000 is can achieve an ozone level of 3 parts per million in a 1700 cu.ft.. room within one minute. 

After 30 minutes, at a distance of 12 feet the ozone level reached 16 parts per million.

This is the type of power required to kill mold and bacteria.

This is a recent test of our XT-6000 ozone generator performed by SGS proving that this machine can produce an ozone level high enough to kill fungi in 30 minutes.

Air-Zone Test Measurements of the XT-6000 Ozone Generator Air-Zone XT-6000 Ambient room temperature: 80.3 F Room size: 17 x 12 x 8.3 foot ( 1693 cubic feet ), no ventilation Ozone Concentration: 22 ppm, Ozone Air Flow Rate: 82 CFM Ozone Output Per Hour: 6500 mg/hr.    Test Time 5 minutes 10 minutes 30 minutes 45 minutes Ozone Concentration 0.3 ppm 0.55 ppm 1.0 ppm 0.9 ppm Test conducted with the measuring instrument at a 5 foot distance from the ozone generator. Test Time 10 minutes 60 minutes Ozone Concentration 0.3 ppm 0.9 ppm Test conducted with the measuring instrument at a 12 foot distance from the ozone generator. Test of Nitrogen Oxides, NO+NO2: The ozone measuring sensor was placed directly in front of the ozone generator. Zero Nitrogen Oxide levels could be detected by the measuring device. Test Conclusions: The ozone concentration is dependent upon the location, and running time of the ozone generator. The 12 foot distance used in the second study is equivalent to placing the unit anywhere in the designated area. Centered in the middle of the room, the unit was never more than 8.5 feet from the furthest point in the room. The ozone generator was found to easily obtain an ozone concentration level of at least 0.3 ppm within 10 minutes of operation, no matter where in the room the unit was placed, or where the ozone concentration was measured. It has been previously proven in University of Pennsylvania studies that E coli bacteria will be killed at average 0.28 ppm ozone concentration within two hours. In our opinion it can then be reasonably concluded that the Air-Zone XT-6000 ozone generator will kill 99% of all E coli bacteria, in a 1700 cubic foot room within a time period of 60-90 minutes. We thus make these conclusions since higher ozone concentrations than needed to kill  E coli bacteria can be obtained in a shorter period of time with the Air-Zone XT-6000. Other recent studies have also proven that ozone concentrations within 0.10 ppm and 0.40 ppm will kill most any bacteria or viruses in a relatively short period of time. It is then reasonably safe to conclude that most other pathogens will also be destroyed by the Air-Zone XT-6000 within a short period of time. It is important to note that  these high levels of ozone needed to kill bacteria, can only be used in rooms unoccupied of people, plants, and animals. Test conducted October 2001

Impact summary: Insects eat $12 million worth of stored grain in Indiana each year, and pesticides have been the tool that grain handlers use to stop them.   Purdue researchers, looking for ways to reduce pesticide use, found a potential alternative in ozone fumigation.   In initial tests, ozone fumigation killed more than 90 percent of major insect pests and cut Aspergillus fungus populations by more than half.   It leaves no residue in grain, does not escape into the environment, and appears to be economically competitive. 
Title: Ozone fumigation could replace pesticides in stored grain.

The United States Food and Drug Administration approves the use of ozone for use in food.
They state that ozone may be safely used in the treatment, storage, and processing of foods as a antimicrobial agent.

The Food and Drug Administration has approved the use of ozone in gaseous and aqueous phases as an antimicrobial agent on food, including meat and poultry. Responding to a petition from the Agriculture and Food Technology Alliance of the Electric Power Research Institute, Palo Alto, Calif., FDA published a final rule that permits use of ozone as a food additive (66 Fed. Reg. 33,829). 

Purdue University, in follow up studies, determine that ozone safely kills mold, mold mycotoxins, and insects in grain stores.  They state that while ozone kills the deadly mold fungi of Fusarium and Aspergillus, that ozone is safer than chemicals. 

Linda Mason, Purdue entomology associate professor and co-author of the study  states:
"The chemicals currently used can kill everything in and around the grain bin, including people. 
With ozone, we're not generating ozone at deadly concentrations, and we have better control over it when it's present."

Dirk Maier, a Purdue agricultural and biological engineering professor, studied how to make the ozone flow efficiently and effectively through grain storage bins. 

Charles Woloshuk, a botany and plant pathology professor, studied ozone effects on molds and mycotoxins. 

The scientists began their study after a company that uses ozone air purification systems in hospitals noticed that air vents were cockroach free. 

Absence of cockroaches in a large building is unusual, so the researchers tested various ozone doses on different insects and found the gas was fatal to bugs.

SCOTTSDALE, AZ — The International Ozone Association (IOA), based here, says that sanitizing towels, linens and surfaces with ozonated water has been shown to be “extremely effective” in the reduction of the staph infection “super bug” MRSA, a methicillin-resistant form of Staphylococcus aureus which has been spreading across the United States, according to a recent IOA press release. 

The Centers for Disease Control and Prevention (CDC) recently reported that in 2005, MRSA, which can start as a serious skin infection, was responsible for more than 94,000 infections and about 19,000 deaths in the United States.

The IOA reports that washing with ozonated water can reduce MRSA and its conventional S. aureus cousin by as much as 99.999999 percent. The CDC has said that good handwashing practices and other forms of hygiene also help prevent MRSA infections, which have been most commonly contracted in health care facilities but have been shown in recent media reports to have occurred in schools.

A paper released last year by the International Ozone Association,“Ozone in the Laundry Industry — Practical Experiences in the United Kingdom,” said that tests by Microsearch Laboratories confirmed that low-temperature ozone washing can effectively inactivated organisms including Clostridium difficile, E. coli, MRSA, Pseudomonas aeruginosa, Candida albicans, Streptococcus faecalis, Aspergillus niger, Clostridium perfringens, Campylobacter jejuni, and Aeromonas, Actinobacter and Lactobacilli.

Air-Zone® Ozone Generators are the most effective tool for removing mold, smoke, pet, and many other stubborn odors. Air-Zone® Ozone Generators safely  KILL MOLD including Toxic Black Mold. Air-Zone® Ozone Machines are thousands of times more powerful than simple ionizers, which cannot possibly kill substantial amounts of mold and bacteria.

In today's times, when everyone is concerned with many types of infectious bacteria, it is a good idea to sterilize rooms with High Ozone Shock Treatments. Killing germs, bacteria, and viruses with ozone may be one of the best ways to protect your family  from the complex array of diseases we face today.

High Ozone Shock Treatments
are an excellent way to kill bacteria & germs

Air-Zone ozone generators help kill mold and bacteria
by attacking them at the source.

Every ozone generator owner should try High Ozone Shock Treatments for sanitizing areas. 
Many times the shock treatment will be enough to freshen the room and the ozone need not be on when the room is occupied. Some individuals are sensitive to even low levels of ozone and High Ozone Shock Treatments are the best method for them to use ozone for great benefit when they are not in the room. the effects of ozone continue to last even after the generator is turned off.

High Ozone Shock Treatments MUST be used to remove mold odors, mold spores, viruses, bacteria, and severe odors such as smoke, or pet odors.
