Ozone for Pools & SPAs: A Natural Treatment!

Did you know that ozone is an oxidizer with a very high oxidation potential? And do you know what that means for pools and spas water treatments?

Ozone for Pools – If you want to know more about this natural solution for water treatment in pools, spas and jacuzzis, just keep reading it!

Ozone does not form chemical compounds, as it does not remain in the water after treatment due to its instability, which means that it does not leave residues because after acting it returns to the oxygen form.

Basically, it means that ozone is an effective treatment for pools and spas, and it acts in the most natural way, avoiding the risk of intoxication by pool chemicals for you and your family!

How does it work?

Ozone pool systems have been used regularly in Europe and other areas of the world since the 1950s, since chlorine-free pools are co-targeting the market for chlorine or chemicals because of the benefits of ozone bath for the health of users of swimming pools, spas and jacuzzis.

The use of ozone filters in swimming pools, spas and jacuzzis is the most efficient, natural and not harmful of water-cleaning treatment, because ozone has an anti-bacterial factor that eliminates water impurities. Ozone water treatment systems for pools and spas are highly oxidizing compared to chlorine, eliminating more effectively microorganisms. Ozone is an effective disinfectant killing bacteria, viruses, spores, mold and algae.

Ozone for pools and spas  as cleaner, can be used alone to treat pools & spas or can be combined with sodium bromide to provide a residual in pools that are not continuously recirculated. However, the systems developed by Solution Ozone® allow the treatment of water from swimming pools, spas and jacuzzis only with ozone due to the optimization of the ozone contact system in the water, ensuring 100% natural and safe treatment and natural solution. Ozone improves both the water quality in your swimming pool, spa or jacuzzi and helps chemical sanitizers work more efficiently.

Chlorine used to disinfect swimming pools, spas and jacuzzis is widely recognized as a health hazard. New studies and research, conducted from Catholic University in Belgium, suggests that children who swim frequently in chlorinated waters may have increased risks of developing allergies or asthma, presumably mediated by nitrogen trichloride (NCI) – a byproduct of chemical pool treatment reactions between ammonia and chlorine that can damage the respiratory thin tissue in children and increase their risk of lung disease.


Ozone is a naturally produced gas that is commonly used as a sanitizing agent to help kill microorganisms in water. The  Ozone for pools, spas or jacuzzis 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.

Here you can find some water treatment benefits where we use ozone for pools, spas and jacuzzis:

  • No smell;

  • Without addition of chemicals – this water ozonization process is 100% natural;

  • No additional monthly costs or needs for additives or consumables – on the long term saves money, because ozone does not need any other products to be effective;

  • Ozone is much more powerful oxidant and disinfectant than chlorine – Some chlorine-resistant pathogens cannot multiply in water that is treated with ozone;

  • Higher-quality and purified water – High-competition athletes prefer to practice in pools where water is treated with ozone, because the water is healthier and free of harmful bacteria and viruses;

  • Ozone has no toxic or harmful residues compared to chlorine. Chlorine is known to create residues like chloramine, THM… the Ozone, by itself, oxidizes organic and inorganic matters in the water without formation of unwanted products, such as chloramines;

  • Increased filtration efficiency and coagulation capacity – biodegradation rate of natural organic matter is increased, so large molecules are diminished into smaller molecules which can be decomposed by the pool filter more easily;

  • Does not change the alkalinity and pH of the water;

  • Can be used in any type of water;

  • Can be installed in hot or cold water pools; Compatible with any type of pool (fiber, vinyl and tile);

  • Prevents clogging;

  • Reduces the possibility of skin and eye irritation;

  • Does not damage or disclose swimsuits, shorts, bikinis;

  • Ozone decomposes rapidly and naturally, and therefore, it leaves no harmful residual that would need to be removed.

And after reading all that, you may be asking: Where can I find an ozone pool or spa near me? Well, make sure you have an Ozone generator system for pools or spas, and you can have one at home, and at the same time you’ll be caring for the health of your family!

Some of the most common problems caused by chloride:

Red eyes and Conjunctivitis:

The most common eye problems caused by chlorinated water are:

  • Conjunctivitis – This infection can be either bacterial or viral and thrives in water because the tear film breaks down and germs get into the eye . It causes irritated, itchy eyes, severe redness and crusting;
  • Red eyes – Chlorine dries out the eyes and, as mentioned earlier, eliminates the tear film. When the tear film is stripped away, the vision may be temporarily blurred or distorted.

Dental enamel erosion and weaker teeth:

“Improperly maintained pool chlorination in swimming pools can cause rapid and excessive erosion of dental enamel,” warned Dr. Leila Jahangiri, a clinical associate professor and the Chair of NYUCD’s (New York University College of Dentistry’s) Department of Prosthodontics.

“If the chlorine levels are not properly maintained, the pool water can become overly acidic,” says Dr Jahangiri. “Regular contact with this acidic water as you swim can cause serious enamel erosion.”

Bladder cancer:

In a study published in the American Journal of Epidemiology, researchers linked bladder cancer risk to exposure to trihalomethanes (THMs). The study showed that swimmers who regularly swim in chlorinated pools have a 57% higher risk of developing bladder cancer.

The doctors thus established a link between bladder cancer and exposure to chlorine byproducts through inhalation and absorption through the skin.

Respiratory problems and asthma:

Respiratory symptoms such as nasal irritation, coughing, and wheezing. Asthma attacks may be triggered in people with asthma.

A study published by the Catholic University of Leuven ( Belgium) linked chloride to the development of asthma in children.

Regular attendance of chlorinated swimming pools by young children is associated with an exposure-dependent increase in the permeability of the lung epithelium and an increased risk of asthma, especially when combined with other risk factors.

Certain respiratory problems are caused by a byproduct formed in the chemical reactions between ammonia and chlorine: nitrogen trichloride (NCI).

Dry Skin:

Chlorine strips away essential oils from the skin and opens the skin pores, causing dry skin. Prolonged contact with chlorine may cause skin rashes, which may develop into blisters with further contact with chlorine.

Green Hair:

Hair dyed blond can turn grass green after being immersed in a chlorinated pool.

This hue does not come from the chlorine itself, but from the reaction of the chlorine with the copper contained in hair dyes.
