Frequently Asked Questions About Ozone

1. What is Ozone?

Ozone is active oxygen, O3. It occurs naturally in the earth's atmosphere to protect us from the sun's harmful rays.

2. What are some uses of ozone?

Some common uses are: pool and spa water purification, drinking water purification, waste water purification, and air freshening.

3. How long has ozone been used to purify water?

Since the late 1800's.

4. How long has ozone been used to purify pool and spa water and remove odors from the air?

Over 50 years.

5. How does the ozone used for water purification affect the air we breathe?

The amount of ozone produced by an ozone generator is insignificant to the normal atmosphere we live in. When dissolved in water, ozone is extremely safe. Excess ozone quickly converts back to oxygen. Note: do not breathe concentrated ozone gas.

6. Is ozone the same as "SMOG"?

No! "Smog" is air pollution created by combustion polluters. While smog contains small amounts of ozone, it is largely composed of harmful chemicals such as carbon monoxide. In fact, smog and other pollutants may contribute to the damage of the ozone layer.

7. If I use ozone in my pool or spa, will I help replenish the ozone layer?

No. Because ozone reacts so quickly with contaminants in water and air, it converts back to oxygen within minutes or even seconds. Any ozone molecules that break free from the pool or spa water will convert to oxygen and never reach the atmosphere.

8. Will ozone hurt me?

No! In the quantities necessary to be effective, ozone is very gentle to humans and equipment in the water. However, you should never breathe concentrated ozone gas.

9. Does ozone have an odor?

Yes. Depending on the concentration, the odor ranges from slightly sweet to moderately antiseptic.

10. Will ozone kill bacteria?

Yes. It is one of the most effective, complete bactericides of all earth's measurable elements.

11. Will ozone kill viruses?

Yes. Ozone kills virtually all known forms of viruses in water and air.

12. How is ozone different from chlorine?

In the quantities needed for water purification, it has no noticeable odor, taste or color. It is not irritating to humans or equipment. Ozone purifies water and air very quickly and efficiently, 3,000 times faster than chlorine. Ozone leaves no by-products except pure oxygen. In contrast, chlorine leaves a chemical by-product called hypochloric acid and additional salts in water applications.
