Ozone or Chlorine - you be the judge

See following chart which contrasts ozone compared to chlorine use in Spa Pools

Natural Chemical
Generated here by way of electrical discharge ozone is nature’s way of cleaning up the environment. Ozone is increasingly recognised and popular as the principal water purifier for spa pools. A potentially harmful chemical and probable carcinogen. According to the U.S. Council of Environmental Quality: "The cancer risk to people who drink chlorinated water is 93 percent higher than those who don't"

Since more is absorbed via the skin when bathing in chlorinated water over drinking it - Do you really want to soak in it?

Most effective Not as effective
Ozone is recognized among the strongest, fastest, commercially-available disinfectants and oxidants for water treatment[1] It is 200 times more powerful than chlorine, and kills 99.99% of all known viruses and bacteria, leaving water safe and clear. Not effective against certain pathogens, eg. Cryptosporidium.
Healthy Toxic
Leaves the water charged with therapeutic ozone. Our skin is the largest organ of your body and since it is porous, it absorbs whatever you put on it or soak in.  There have been some promising studies examining how ozone may be beneficial to health[2] by:
  • Inactivating bacteria, viruses, fungi, parasites, yeast, and protozoa
  • stimulating the immune system to speed up healing
  • improving circulation by cleaning the arteries and veins
  • purifying blood and the lymph
  • normalizing hormone and enzyme production
  • having anti-inflammatory properties
  • reducing pain
  • stopping bleeding         
  • preventing shock
  • limiting stroke damage     
  • reducing cardiac arrhythmia or abnormal heart rhythm
  • reducing the risk of complications from diabetes
  • improving brain function and memory
A study published in the American Journal of Public Health looked into the skin's absorption rates of chemicals found in drinking water. It showed that the skin absorbed an average of 64% of total contaminant dosage[3].   That is more than drinking chlorinated water itself.   Long term effects of bathing in chlorine is believed to cause
  • acne
  • eczema
  • rashes
  • cancer
  • dry skin  
  • premature aging
  • depleted proteins and dry skin
Long term savings Ongoing cost
One-off investment. We have been servicing the industry for two decades and the corona discharge technology is very durable. Recurrent cost of purchasing chemical
No residual effect on water after treatment Leaves water with toxic residue
Minimal servicing required Daily servicing
Once its installed the ozone generator will automatically come on with your spas timer so no regular maintenance is required A lot of work with chlorine needing to be added to the spa on a daily bases
Low maintenance High maintenance
Ozone is PH neutral it reduces the need to use shock, metal out, pH Up and pH Down, water clarifiers and adjusters Need to do regular PH tests etc
