Once you’ve decided to purchase a hot tub, you will have the opportunity to make many choices that can enhance the quality of your spa experience for years to come. Some of the most fun choices to make will be determining the seating configuration that is best for your needs, selecting the hot tub with the best jets to soothe and relax you, picking out cabinet color, and opting for upgrades to complete your hot tub oasis.

Other choices will determine not only the cleanliness and health of your hot tub’s water, but how hard you will have to work to maintain its chemical balance. This will depend heavily on the hot tub company, the model, and the water management and filtration systems of the hot tub you choose. Naturally, this is a very important decision and one that you should feel confident about as you select the best spa for your needs.

This article will help you understand the complexities of clean and healthy hot tub water, inform you of the different water systems and treatment options, and share with you the dedicated approach that the Jacuzzi® company takes when it comes to water care. It will also offer examples of some of the best hot tubs for clean and healthy water.

What is clean hot tub water?

The answer to this question is important to define from a technical standpoint. Quite simply, Jacuzzi® Hot Tubs are designed for you to sit back and relax while the water goes to work. While this sounds easy, the water management technology is advanced. Jacuzzi® combines ozone and UV-C technology to provide you with a nearly hands-free approach to your hot tub water care.

The Jacuzzi® CLEARRAY Active Oxygen® System works harder to clean* the water longer. Through this system, ozonated water is exposed to a UV-C bulb to energize the molecules, unlocking the Active Oxygen to clean.* UV-C technology is standard on all Jacuzzi® Hot Tubs models.

Furthermore, Jacuzzi® Hot Tubs feature a 5-Stage** filtration process, which delivers cleaner* water. This means fewer water changes and less effort on your part. The stages are:

Stages 1 and 2 —

The skimmer and unique mesh ProCatch™ filter work together to clean the water surface and trap large debris for easy removal.

Stage 3 —

This exclusive system features a 60-square-foot ProClarity® filter connected directly to a ProStream filtration pump that filters an impressive 35 gallons per minute, thus giving you clean* water faster.

Stage 4 —

The ProClarity® depth load filter polishes the water down to a 3 micron level.

Stage 5 —

The second 60-square-foot ProClarity® filter cleans and activates when you are using your hot tub. This doubles the filtration when you need it most.

What are some hot tub water care treatments and systems?

Sanitation of your hot tub water is vital to the health of your spa. There are a few common options, and it’s important to understand each prior to purchasing a hot tub. Generally, the hot tub you select will have a specific system or water treatment method that accompanies it. The three most popular hot tub sanitation types are UV, ozone, and saltwater. Read on for a brief description of each:

UV (or Ultraviolet Light) —

A UV sanitation system employs UV-C germicidal light rays to assist in keeping your hot tub water clean* and bacteria-free. This system is designed to prevent organic matter such as algae or bacteria from reproducing. It does so by disrupting the DNA or RNA of these organisms. While this system is an effective sanitizer, it does not oxidize your hot tub water. It will still need to be oxidized with chlorine, bromine, or a non-chlorine shock product.

Ozone —

Ozone gas both oxidizes and sanitizes hot tub water. With this treatment, an accessory called a hot tub ozonator can be attached to a jet which infuses ozone into the water. The ozone generator can help break down contaminants in the water and remove impurities from the water. This approach allows you to use less chemicals. It also requires less maintenance than other options.

Saltwater —

This water treatment option is often thought to be chlorine- or chemical-free, but that is a misconception. In fact, a saltwater system produces its own chlorine. While they are believed to be gentler on the skin and eyes, this option can actually be harsh on your hot tub’s components.

What are the best hot tubs for clean and healthy water?

This is just one more aspect of hassle-free hot tub ownership that Jacuzzi® Hot Tubs employs so you can relax while your hot tub goes to work.

It is important to keep in mind that how often you use your hot tub, the climate in your area or extreme seasonal weather, and water quality in your area can vary and can also affect your water care routine. These are reasons why the proper levels of filtration and water management systems are so vital to your peaceful hot tub experience.

Chances are you are looking for a hot tub to help you relax and destress from your day, not to add any unnecessary worries to your mind. Ultimately, the visually stimulating effect of seeing the crystal blue water before you settle into a soak is the beginning of your hot tub experience.

You should be able to get into your hot tub and relax—not only into the sensations of the warm, bubbly water washing over your skin but into also the peace of mind that your water is being properly maintained.

UV-C technology is standard on all models.

*Clean is defined as the removal of microscopic (down to 3 micron level, varies by model) debris from the water.


The CLEARRAY Active Oxygen® System utilizes various technologies to achieve cleanliness. One of them is ozone, which aids in the grouping of smaller debris to form larger clusters that can be more easily captured in the filtration process.

**Stages of filtration may vary by collection.
