Traditional hot tubs rely on sanitizers like chlorine or bromine to keep water safe. Without them, bacteria and algae can quickly grow. However, advanced systems such as nanobubble technologies can greatly reduce or nearly eliminate chemical use. Jacuzzi® True Water® uses trillions of oxygen-filled nanobubbles to scrub contaminants and deliver water that’s 99.9999% chlorine-free—cleaner than drinking water.

Eco-friendly spa care options include mineral systems that use silver and copper ions, ozone and UV-C systems that oxidize and neutralize contaminants, enzyme-based treatments that break down residues, and saltwater systems that create softer-feeling water. True Water® goes further, delivering a natural, sustainable spa experience that’s virtually chlorine-free and gentle on both skin and the environment.

Each spa water system offers a balance of effort, cost, and chemical use.

• Traditional chlorine/bromine: Reliable but require frequent testing and adjustments.
• Salt systems: Reduce manual dosing but still generate chlorine.
• Ozone, UV-C, or ionizers: Minimize chemical needs but require a small backup chemicals.
• Biguanide: A gentle non-chlorine alternative that needs more upkeep.
• True Water® nanobubbles: No daily care, 99.9999% chlorine-free, and only 15 minutes of monthly maintenance.

True Water® stands apart for effortless upkeep and crystal-clear, soft, naturally fresh water.

Simple habits combined with advanced technology make spa care easy. Clean filters weekly, test pH and alkalinity, and drain every few months. With True Water®, that’s all you need—no daily balancing, no harsh smells, and no residue. Owners report clear, fresh water that feels soft and natural with just a quick monthly cartridge change.

Low-chemical systems like True Water® save time and reduce ongoing costs tied to chemical purchases. The result is water that’s softer on skin, easier on equipment, and more enjoyable overall. While the initial investment may be higher, many owners find the simplicity, comfort, and long-term value make it a worthwhile upgrade.

True Water® uses nanobubble technology—trillions of microscopic oxygen bubbles that stay suspended for days, scrubbing every surface and neutralizing 99.9% of bacteria and viruses without harsh chemicals. Inspired by nature and used in advanced clean-water applications, it’s a breakthrough that keeps your spa crystal clear with almost no chlorine at all.

True Water® continuously oxygenates and purifies your spa through nanobubble technology. These nanobubbles disrupt and remove bacteria and viruses naturally, maintaining a clean, safe soaking environment.
