Frequently Asked Questions


? Does it have sanitizing properties?
Yes, it does. Ozone is one of the most effective ways to combat bacteria and pathogens from both water and air.

? Is it harmful to humans?
No, it’s not harmful. The required quantities for sanitizing water are, in fact, harmless to humans, pets or equipment. However, it is not recommended to breathe it in.

? Does it interact with other chemicals?
Ozone has a neutral pH, so it won’t affect the water or the other chemicals, but high water temperatures can lessen its efficiency. Additionally, from time to time it is advised to use chlorine to supplement the ozone’s efficacy.

? How does ozone works?
Ozone is made of up of three oxygen atoms, which makes it highly unstable. The third atom will always seek to escape, thus it will bind, or oxidize, with any other compound which allows it. Therefore, it will purify water and air, removing pathogens and bacteria that come in contact with it.

? Do I still have to filter the pool water?
Yes. Although ozone does take care of the majority of impurities, filtering the water will sanitize it further, ensuring even the tiniest algae particles are kept away from the water.

?How long does ozone last in water?
Due to its highly unstable aspect, it will last only a few minutes, from 3 to 20 minutes, to be more precise. Thus it is recommended to add a small amount of chlorine, to preserve the effects.

? Does it affect pool maintenance?
Yes, it will help reduce the overall time spend on cleaning and clarifying the water. Although it will make the water a bit cloudy when used the first time, the cloudiness will disappear as soon as it has finished removing the bacteria and residues present in the water. Even more, you can pair it up with a solar ionizer which will further sanitize the water in an eco-friendly way.

? What are some of the benefits of using one?

  • Reduced maintenance time
  • No chemical odors
  • Water becomes gentler with skin, eyes, hair and equipment
  • Reduced costs
  • Less amount of chemicals used to preserve the water clarity
  • Improves filter and pump operation
  • No harmful effects on humans, animals, or environment
