Health Hazards of Chlorine Swimming Pools

Chlorine used to disinfect swimming pools is widely recognized as a health hazard. New research suggests that children who swim frequently in chlorinated pools may have increased risks of developing allergies or asthma. Among adults exposure to chlorine in swimming pools has been linked with other health problems including bladder and rectal cancer and, possibly, an increased risk for coronary heart disease.

Other negative effects caused by chlorine in swimming pools and spas:

  • Asthma
  • Dental Enamel Erosion
  • Spontaneous abortion and stillbirths in pregnant women
  • Bladder Cancer
  • Chlorine causes corrosion of swimming pool stainless steel and components

Benefits of Using Ozone for your Swimming Pool Application:

The Ozone pool will be much cleaner, which means dirt, grease, oils, organics and other materials will wind up in the filter system much faster than with chlorinated systems. That is why, proper maintenance of the filter system is important.


Part of the problem in adopting Ozone is that engineers, architects, pool builders and designers are not familiar with the technology. Some applications of Ozone, particularly systems installed 10-15 years ago were plagued with technical problems. Even though Ozone systems have been in regular use in Europe and other areas of the world since the 1950's, pools here have generally relied on chlorine. Since our engineering, architectural and other technical training have all been geared to Chlorine, it takes re-education to now apply Ozone. Many people in these industries are reluctant to "shift gears" and take the time to educate themselves about the proper and successful application of Ozone.


What is the difference in technologies? Chlorine is a complex man-made chemical that found original use in the infamous "mustard gas" of the First World War. Ozone has been in use for over 100 years, primarily in Europe and was first put to use for water purification, odor control and in medical hospitals (it is still being used medically today, though not commonly in North America).

Other Benefits of Using Ozone for your Swimming Pool Application include:

  • No chlorine smell - Ozone oxidizes organic and inorganic matter without forming byproducts such as chloramines (which are responsible for chlorine smell)
  • Decrease in Chlorine use - saves money on cost of chemicals on the long term
  • Healthier swimming water - water quality will be safer and healthier for active pool users and swimmers
  • Ozone has no toxic or harmful residues in comparison to chlorine which is known to create residues (Chloramine, THM etc.)
  • Increased Filtration Efficiency -  biodegradation rate of natural organic matter is increased, large molecules are diminished into smaller molecules which can be decomposed by the pool filter more easily
  • Ozone prevents clogging and and increases filter capacity
  • Ozone will prevent eye irritation
  • Ozone will not discolor bathing suits

Selecting an Absolute Ozone® Ozone Generator for your pool

We recommend selecting ozone generator according to the German DIN 19643 norms. In these norms amongst others a temperature dependent ozone dose is used.


We recommend for chemical free pool residual ozone concentration of 0.03ppm - 0.05ppm.


For swimming pools with a water temperature of 28°C or 33 - 35°C an ozone dosage of respectively 0.8 and 1.2 gram per m3 is used.


The most important saving when you install an Absolute Ozone® ozone system is that there will be nothing for you to do.

No chemicals to administer, to buy or too store, no chemical tests, no PH balancing, no clarifiers, no algaecides, no cleaning of an ugly yellow deposits on the water line, etc.

The cost of the maintenance of your pool will drop to almost nothing if you consider the cost of the time one has to spent maintaining the pool instead of resting and enjoying life and that is when Absolute Ozone® system will make a difference.


Also having a completely chemical free pool is considerably more pleasant and healthier, plus the water will be crystal clear and good enough for drinking.

As one of our competitors say "you will be swimming in a bottling water".


As to all of our customers we will provide unlimited technical support to you with your project to assure that it is successful, from system design, to commissioning to tuning and most importantly without an expiration date.
