The Purezone™ AOS system combined with the Purezone™ filtration system is one of the most effective automatic water care systems on the market.

The Purezone™ AOS water care system consists of a series of components, including:

  • an Ozone generator that produces the oxidant
  • a UV light Chamber where the oxidant and UV Light are combined to form the hydroxyl radicals

A combined ozone and UV system is more effective at sanitising spa pool water than using Ozone or UV light alone. This is because both technologies work together, enhancing each other’s strengths, to achieve a higher level of water disinfection and purification.

One key benefit of this combination is when ozone and UV light are used in a spa pool, they create hydroxyl radicals, which are very powerful at cleaning the water.

Overall, a combination UV and ozone sanitising system such as Purezone™ AOS, can provide a reliable, low-chemical way to keep spa pool water clean, clear, and safe for users.

What are hydroxly radicals?

Hydroxyl radicals are highly reactive molecules that play a crucial role in advanced water treatment processes.

As mentioned above, when ozone and UV light are used together in a spa pool, they create hydroxyl radicals, which are very powerful at cleaning the water.

Hydroxyl radicals are known for their powerful oxidizing properties, which make them extremely effective in breaking down a wide range of contaminants, including organic pollutants, bacteria, viruses, and chemical compounds.

In fact, these radicals can break down organic contaminants in the water more effectively than just using ozone or UV alone, helping keep spa pool water clean and safe to use by attacking and removing harmful substances.
