Clean hot tub brands: How Jacuzzi® True Water® is revolutionizing hot tub water care

What is nanotechnology, and how can it keep your hot tub clean1?

Nanotechnology is the science of manipulating matter at the molecular or atomic scale. In hot tubs, it’s used in the form of nanobubbles—tiny oxygen-filled bubbles that are 5,000 times smaller than a grain of sand. These bubbles stay suspended in the water, where they actively cleanse and purify it.

Discovered by Japanese scientists in the 1990s, nanobubbles naturally occur in the environment but are now harnessed for high-performance water care and other innovative uses. When used in Jacuzzi® Hot Tubs, they continuously remove contaminants3 and residue along the waterline and even in the plumbing. Nanobubbles clean 2.5 times faster than regular tap water, offering a superior alternative to chemical-heavy treatments. And with trillions of these oxygen-filled nanobubbles continuously floating through your hot tub water, scrubbing away contaminants3 that they encounter, you can rest assured that your water will be sparkling clear and fresh when you are ready for a soak.

How True simplifies hot tub ownership

The True system generates a constant stream of nanobubbles that scrub and clean1 the water 24/7. Third-party lab tests show that the system can remove 99.9% of bacterial and viral contaminants3—without traditional chlorine or bromine.

Here’s what makes True stand out:



• Minimal upkeep: Spend just 15 minutes a month on maintenance.
• Smart integration: Compatibility with the Jacuzzi® SmartTub® system and app put remote monitoring and control at your fingertips.
• Gentle on skin and hair: Say goodbye to that pesky chlorine smell and post-soak dryness.
• Cleaner water, longer enjoyment: Spend more time relaxing and less time managing chemicals.
