Chemical-free hot tub options: Jacuzzi® hot tubs with Jacuzzi® True Water®

11 Minute Read

Hot tubs are more than just a luxury item—they are your gateway to relaxation, wellness, and elevated living. When you bring a hot tub into your home or backyard, you are giving yourself and your loved ones the priceless gift of self-care. Whether you’re seeking temporary relief from aches and pains, looking to unwind after a long day, or hoping to reconnect with family and friends, a hot tub can enhance your lifestyle in countless ways.

One of the most important considerations when purchasing a hot tub is water care. Many prospective buyers ask the same question: “Is there such a thing as a chemical-free hot tub?” In your own personal hot tub research, you may have wondered the same thing. The answer is that no hot tub can be completely chemical-free—some level of sanitization is always required to ensure safe, healthy soaking.

However, innovative systems are making hot tubs closer to chemical-free than ever before. Jacuzzi® True Water® is one such solution, offering an advanced water care system that provides one of the purest and more natural soaking experiences possible today.

This article will explore the concept of chemical-free hot tubs, explain how Jacuzzi® True Water® works, introduce the science of nanotechnology, and show why Jacuzzi® hot tubs stand out in creating water care systems that are as close to chemical-free as possible.

Can you have a chemical-free hot tub?

Like swimming pools, hot tubs require ongoing maintenance to keep the water safe, clean1, and clear. Traditionally, this has meant relying on chemicals such as chlorine or bromine. These chemicals disinfect the water, kill harmful bacteria, and maintain balanced pH levels. However, many hot tub owners dislike the smell, residue, or skin sensitivity that comes with chemical treatments.

For these reasons, a growing number of people are looking for alternatives to heavy chemical use. While it’s impossible to maintain a completely chemical-free hot tub, you can significantly reduce your reliance on chlorine and bromine by investing in advanced purification systems like Jacuzzi® True Water®.

What is Jacuzzi® True Water®?

True is a revolutionary water care system designed to minimize the need for traditional chemicals. After three years of research and testing, the Jacuzzi® brand introduced this breakthrough to make hot tub ownership easier, cleaner, and more eco-conscious.

The science of nanotechnology in water care

Nanotechnology refers to manipulating matter at the molecular or atomic level. In the case of True, it involves the creation of nanobubbles—tiny, oxygen-filled bubbles thousands of times smaller than a grain of salt.

How nanobubbles work:

Suspended action: Nanobubbles remain suspended in the water rather than rising and popping at the surface. This allows them to work continuously throughout the hot tub.
Enhanced cleaning: They scour contaminants, debris, and microscopic impurities—including bacteria and viruses—while reducing the need for added chemicals.
Faster results: Studies have shown nanobubbles clean water at rates up to 2.5 times faster than tap water, keeping surfaces and waterlines clearer for longer.

This natural, oxygen-driven cleaning process creates healthier, fresher water while dramatically reducing chemical byproducts and off-gassing.

How does True work?

True integrates nanobubble technology into your hot tub’s water care system. These oxygen bubbles remain suspended in the water, continuously purifying the tub at a microscopic level. They:

Clean not only the water but also the hot tub surfaces, plumbing lines, and the waterline.
Remove up to 99.9% of bacterial and viral contaminants2 without heavy reliance on chlorine or bromine.
Keep water fresher for longer, meaning fewer manual interventions and less frequent water changes.
True Water® leverages nanotechnology to continuously purify water. By generating billions of microscopic oxygen nanobubbles, it creates water that is up to 99.999% free of traditional hot tub water cleaners—an exceptional level of purity that rivals even drinking water standards3. With less reliance on chemicals, your hot tub becomes a healthier, more enjoyable space for you and your loved ones.

Even more impressive, True dramatically reduces the time you spend on maintenance. Traditional hot tubs often require weekly testing and chemical balancing, but with True Water®, you’ll spend only about 15 minutes a month4 on upkeep. That means more time enjoying your spa and less time worrying about water care.

What sets True apart?

Compared to traditional hot tub systems, Jacuzzi® True delivers a nearly chemical-free soaking experience through advanced design and engineering.

Benefits of True:

Better for skin and hair: No chlorine odor, dryness, or irritation—just fresh, natural-feeling water.
Healthier environment: Reduced chemical exposure makes soaking more comfortable, especially for those with sensitive skin or allergies.
Cost-effective: Lower reliance on chemicals means long-term savings on maintenance products.
Eco-friendly: Reduces chemical runoff and environmental impact through sustainable purification technology.

Important note on chemical-free claims

It’s essential to understand that no hot tub is completely chemical-free. Even with advanced systems like True, some minimal use of sanitizers may be required depending on your water source, usage, and maintenance habits. The Jacuzzi® brand provides detailed guidelines to ensure your spa water remains safe and enjoyable. Always follow your hot tub manual and maintenance instructions to achieve the best results.

While a 100% chemical-free hot tub isn’t possible, True gets as close as you can realistically achieve. Through the power of nanotechnology, it reduces the need for chlorine and bromine, simplifies maintenance, and provides healthier, more natural water. Combined with the Jacuzzi® brand’s commitment to innovation and wellness, True makes hot tub ownership easier, safer, and more enjoyable than ever.

If you’ve been searching for a way to minimize chemical exposure in your hot tub while maximizing comfort, clarity, and peace of mind, Jacuzzi® True Water® offers a solution that redefines what clean, holistic soaking can be.

1Clean is defined as the removal of microscopic (down to 3-micron level, varies by model) debris from the water.
