FREQUENTLY ASKED QUESTIONS
Q. WHAT IS OZONE?
A. Ozone (O3), a tri-atomic form of oxygen, is nature’s sanitizer, deodoriser and air purifier. Ozone is the second most powerful sterilent in the world and it reacts with organic compounds to oxidize unpleasant odors, kill germs, bacteria and viruses. Ozone is often called enriched or activated oxygen because it is unstable containing three oxygen atoms instead of two. It is significant to note that the highest naturally-occurring ozone levels, about 0.05 to 0.065 parts per million (ppm), are found at the seashore, in forests, or in high mountainous areas
Q. HOW DOES OZONE NEUTRALISE ODOURS?
The highly reactive quality of Ozone makes it a powerful and efficient cleaner and purifier. Ozone will react with almost anything, including chemical sources of unpleasant or hazardous indoor odours. Unlike other deodorisers ozone does not simply mask odors but actually destroys them.
Q. WHAT ORGANISMS DOES OZONE KILL?
• Bacteria – (such as E-coli, salmonella, streptococcus, cholera) etc.
• Viruses – (such as influenza, poliovirus, hepatitis).
• Fungi, mold, mildew, & spores, etc
Q.WHAT HAPPENS TO OZONE AFTER IT SERVES ITS PURPOSE?
A. When it combines with the other organic substances it oxidizes them causing them to be destroyed and eliminated from the air. The byproduct of this oxidation process is life-giving oxygen. It leaves no harmful residues. This makes it far superior to chemical purification like chlorination
Q. HOW IS OZONE FORMED IN NATURE?
A. Ozone is produced by ultraviolet light from the sun’s rays. A second more common source of ozone in nature is the lightning bolt. That’s why the air smells so fresh and clean after a thunderstorm – the ozone has oxidised the pollutants in the air. Ozone is also a product of plant photosynthesis
Q. CAN OZONE BE STORED?
A. Because of the instability of gaseous ozone, it cannot be generated and stored for later use. Consequently, ozone must be generated at the point of use for deodorisation, disinfecting and sterilization purposes
Q. AT WHAT LEVELS CAN HUMANS BEGIN TO SMELL OZONE?
A. Humans can begin to smell ozone at various levels depending upon their sensitivity, generally 0.003 to 0.015 ppm. Ozone becomes intolerable at 1.0 ppm – way before anything close to a toxic level can be reached. Some physical symptoms of excessive ozone exposure may be burning eyes, difficulty in breathing and nasal irritation.
Q. IS OZONE SAFE FOR HUMANS?
A. Yes, completely safe if employed properly. Like virtually anything, it can be harmful if you’re exposed to too much for too long. Ozone has proven both harmless and e ective. It is significant that ozone at any concentration has not been responsible for any accidental fatality in more than 90 years of industrial use!
Q. WHAT IS THE RECOMMENDED PROCEDURE FOR OZONATING A ROOM?
A. For strong odors, it is advisable to evacuate the area and sterilize with ozone till the odour is neutralised. Next wait for about 30 minutes for any residual ozone to convert to oxygen and then reoccupy. A similar procedure can be employed for disinfecting hospital wards, operating theatres, etc. For mild odours and to maintain freshness levels in the room, the ozone control can be adjusted to an appropriate low setting. Unnecessary excess build-up of ozone should be avoided
Q.WILL THE ODOR COME BACK?
A. No. Ozone destroys the source of odor. However, in the case of mildew the odor will return if you are unable to get rid of the moisture that is the source of the mildew.
Q. HOW DOES OZONE HANDLE TOBACCO SMOKE?
A. It eliminates the irritation caused by phenol gases, by oxidizing them. Phenol gases are the invisible part of tobacco smoke that causes such discomfort to one‘s eyes and create the offensive odors. Although ozone cannot remove the visible particles of smoke, it completely rids any environment of the effects of smoke.
Q. CAN YOU SHORT- LIST THE MOST COMMON AREAS OF APPLICATION OF OZONE?
The applications are virtually endless Homes, Apartments, Kitchens, Toilet, O ces, Commercial establishments, Stores, Department stores, Conference rooms Hotels,Restaurants, Pubs, Bars, Hotel rooms, Clubs Hostel dormitories, Locker rooms, Changing rooms, Day care centres Hospitals, Nursing homes, Operating theatres, Autopsy rooms,Morgues Beauty parlors, Veterinary hospitals, Clinics, Kennels Smoke filled areas, Chemical labs, Paint shops, Fire Restoration Food & Pharmaceutical industry
Q. WHY DO SOME OZONE GENERATORS ALSO PRODUCE NEGATIVE IONS?
A. Some Ozone generators also produce Negative Ions because although ozone is an excellent oxidising agent, it cannot remove solid air-borne pollutants like dust, smoke, soot, pollen, etc. Ions are very effective at this task by a process called “electrostatic precipitation”. Ions are also known to be beneficial to health
Q.WHY IS OZONE NOT IN REGULAR USE?
A. Until very recently, ozone generators were large and expensive and therefore not
practical for common applications. With modern technology, it is now possible to produce
ozone electronically with small, low-cost generators even for day-to-day applications.
