Spa Ozonator reviews: What is an outdoor spa ozone generator and what does it do?


If you're to buy a hot tub or swim spa in your backyard, or if you already have one, you may need to care about the water quality or want the water cleaner. Then it's time to learn something about outdoor spa ozone generator, or spa Ozonator for short. 

What is Ozone?

Ozone, or O3, is a colorless gas that is made when three oxygen atoms are bound together when oxygen(O2) is exposed to ultraviolet light. Ozone is the same gas that creates the protective ozone layer found in our Earth's stratosphere.

Ozone has the protecting effects in your hot tub as well. Ozone helps kill bacteria, germs, viruses, and other contaminants in your swim spa, even without strong spa chemicals like chlorine, bromine, biguanide, mineral sanitizers, salts, etc. Ozone will attach itself to all sorts of gross and grimy contaminants in hot tub water, including lotions and potions like soap, makeup, cologne, sunscreen, and hair spray.

However, we could not obtain natural Ozone gas in large quantities. We need equipment or machines to produce ozone. That's why you need an ozone generator for your hot tub.

What is the ozone generator?

Spa ozone generator, known as Ozonator, is an ozone machine that produces ozone gas to clean the water in your hot tubs or swim spas. With an Ozonator, you'll use less chemical sanitizers like chlorine and bromine, and save money in the long run.

According to the feedback of clients who buy hot tubs from us, with a spa ozone generator, you'll save up to 90% of the total cost each year for popular chemical sanitizers like chlorine or bromine.

How does a spa Ozonator work

The Ozonator, known as a spa ozone generator, is integrated inside the body of your hot tub. Usually, the Ozonator is equipped with an ultraviolet light bulb that converts oxygen into ozone. The ozone travels through an air line connected to a water jet. The water and the ozone are then pushed into the hot tub.

Once the ozone is injected into hot tub water in your spa, it helps sanitize the water by killing bacteria, contaminants, and other waste.

Besides, ozone breaks down body oils, harmful chemicals, and other biodegradable materials to keep the water pure and clear.

How to choose an ozone generator for your hot tub?

You need to consider the top 3 aspects before buying an ozone generator:

  • Hot tub size

There are large hot tubs and small hot tubs to choose from. The size of Royal Spas hot tubs ranges from 2 people, three people, and up to 10 persons. Of course, the larger volume of the hot tub, the more powerful Ozonator you'll have to buy.

  • Sanitation level

If you use your hot tub very frequently with many people, for example, two or three days per week, choose a better sanitation output.

  • Electrical requirements

Consider the voltage cord properly. Ozone units come with a variety of voltage options from 120 volts, 240 volts, or dual voltage.


The ozone generator is the most effective way to sanitize your hot tub water at the lowest cost.

If you use Ozonator together with bromine, chlorine, or other sanitizers, ozone generator not only reduces the amount of those need to maintain clean water but also ultimately enhances the performance of those sanitizers.
