Spa cleaning without harsh chemicals: the future of chlorine-free hot tubs

10 Minute Read

Spas and hot tubs have long been symbols of relaxation, wellness, and luxury. They allow us to unwind, ease sore muscles, and reconnect with friends and family in a serene environment. But along with the enjoyment, hot tubs also come with the responsibility of maintenance, particularly water care.

For many, this means the constant use of chemicals like chlorine and bromine, which can have a range of downsides, from unpleasant smells to skin irritation. This leads many people to wonder, “Can you have a chlorine-free hot tub?” The good news is that, thanks to innovative technologies introduced by the Jacuzzi® brand, you are now one step closer to that goal.

This article will introduce you to the idea of spa cleaning1 with hardly any chemicals with the brand’s newest advancement: Jacuzzi® True Water™. This system uses nanotechnology to make spa water care easier than ever before. In this article, you will learn about True, what nanotechnology is, and how True can help ease hot tub maintenance like never before.

The benefits of True and how it uses nanotechnology to approach spa cleaning1 without harsh chemicals

Traditionally, hot tubs, much like swimming pools, require regular water treatment to keep the water clean1 and clear. Chlorine and bromine have been the go-to chemicals for this task for many years. These chemicals can effectively kill bacteria, viruses, and other harmful microorganisms that might contaminate the water. However, they come with a series of challenges.

For example, chlorine has a distinct smell that some find unpleasant. It can also leave your skin feeling itchy, and your hair feeling dry after a soak. Some people even suffer from allergic reactions to chlorine, making the experience uncomfortable or even harmful. These concerns have led many hot tub owners to search for alternative solutions to chlorine-based water care.

Is there really a chlorine-free hot tub?

Thanks to advancements in technology, particularly nanotechnology, the possibility of a nearly chlorine-free hot tub has become a reality. One of the leading innovations in this space is True, which provides a nearly chlorine-free experience with the use of effective yet gentle nanobubbles. This revolutionary water care system can transform your approach to hot tub maintenance and water cleanliness1.

What is nanotechnology?

Before diving into how this technology works in hot tubs, it’s helpful to understand what nanotechnology is and why it’s so effective. Nanotechnology involves materials at the nanoscale—typically between 1 and 100 nanometers. At this scale, materials can behave very differently from their larger counterparts. For instance, nanobubbles—which are tiny, oxygen-filled bubbles smaller than a grain of sand—have been found to be incredibly efficient at cleaning1 and purifying water.

First discovered in the 1990s by Japanese scientists, these nanobubbles are stable, neutrally buoyant, and remain suspended in water for long periods. This makes them highly effective at cleaning1 water and scrubbing surfaces. Nanobubbles have been shown to be 2.5 times more effective than regular tap water at removing contaminants2, and they require hardly any chemicals.

Introducing Jacuzzi® True Water™

The Jacuzzi® team has leveraged the power of nanotechnology to help create the True Water™ system, a breakthrough in hot tub maintenance. This system uses oxygen-filled nanobubbles that are 5,000 times smaller than a grain of sand—so small that they are invisible to the naked eye. However, they can be seen by a green laser light. These tiny bubbles continuously scrub the water and surfaces of your hot tub, keeping the water clean1 without the need for traditional chemicals, such as chlorine or bromine.

True is so advanced that it can maintain water quality to a degree that is even better than what traditional chemicals can achieve. Third-party lab results show that True can remove 99.9% of bacterial and viral contaminants2 from the water—without the use of nearly any chlorine or other chemical additives. In fact, a Jacuzzi® Hot Tub equipped with True can be 99.9999% chlorine-free, which is even less than in most drinking water3.

How True works

True works by generating nanobubbles that are constantly present in the hot tub water. These nanobubbles are capable of cleaning1 and purifying the water without being felt or seen. They attach themselves to contaminants2 and debris in the water, removing them in a way that traditional chemicals can’t.

In addition to purifying the water, the nanobubbles also work to clean1 the surfaces of the hot tub, including the water lines and plumbing. They do this by gently scrubbing the hot tub’s surfaces, removing contaminants2 that can accumulate over time. According to Moleaer, a leader in nanotechnology, nanobubbles can stay suspended in liquid for weeks, constantly cleaning1 and improving water quality.

The benefits of a nearly chlorine-free hot tub

True offers several key benefits, especially for those who want a more holistic approach to water care in their hot tub. Here are some of the standout advantages of using a hot tub with True:

Nearly chlorine-free experience

With True, your hot tub will be almost entirely free from chlorine, with only a minimal amount needed. This means you won’t have to deal with the often unpleasant odor of chlorine, or the drying effects it has on your hair and the itchy feeling it can leave on your skin. After using your hot tub with True, you’ll feel refreshed, not itchy or dry.

Reduced chemical exposure

For those who are sensitive to chemicals or simply prefer to avoid them, True offers a healthier hot tub alternative. You won’t have to worry about exposure to the harsh chemicals found in traditional hot tub treatments. This is especially important for individuals with allergies or skin sensitivities.

Less maintenance time

Traditional hot tubs require regular maintenance to keep the water balanced and free from contaminants2. With True, however, maintenance is significantly simplified. In fact, you only need to spend about 15 minutes4 per month maintaining your hot tub.

Cleaner1 water

Because the nanobubbles in True work constantly to remove impurities and maintain the water quality, your hot tub will have consistently clean1 water, making it a more pleasant environment in which to relax and unwind.

No more chlorine smell or residue

Without the typical chlorine smell and residue, your soak with True will be fresh, and you won’t have to worry about lingering chemical smells.

Eco-friendly and sustainable

By reducing the need for traditional chemicals, True is not only better for your health, but also for the environment—with fewer chemicals, less impact on water systems, and less waste. With nanotechnology, cleaning1 is more efficient and fewer resources are necessary to achieve better results.

Minimal maintenance with maximum benefits

One of the most impressive aspects of True is the minimal time required for maintenance. Traditionally, hot tub owners need to spend a considerable amount of time checking water chemistry, adjusting pH levels, and adding chemicals to keep the water balanced. With True, you only need to spend around 15 minutes4 per month on maintenance. This gives you more time to enjoy your hot tub without worrying about constant upkeep.

True is also compatible with the Jacuzzi® SmartTub® System. This remote monitoring system and app allows you to control, monitor, and manage your hot tub directly from your smartphone, making it even easier to keep track of your water’s condition to ensure everything is running as expected.

Which Jacuzzi® Hot Tubs offer True?

True comes standard on models in the Jacuzzi® J-LX® and J-400™ collections, providing an elevated, nearly chlorine-free experience. It is also available as an optional upgrade for models in the J-300™ Collection. Whether you’re in the market for a new hot tub or looking to upgrade your existing one, choosing a Jacuzzi® Hot Tub with True means you’re investing in a more efficient, nearly chemical-free way to enjoy your hydrotherapy sessions.

Is a chlorine-free hot tub right for you?

Determining whether or not a nearly chlorine-free hot tub is right for you is a personal decision. However, if you’ve been searching for a nearly chlorine-free hot tub that doesn’t require the use of lots of harsh chemicals, requires less maintenance time, and provides superior water cleanliness1, the answer to that question is likely a resounding yes.

Whether you’re new to hot tubs or looking to upgrade your current model, a Jacuzzi® Hot Tub with True is the ultimate way to enjoy the luxury of hydrotherapy without the hassle of harsh, traditional chemicals.

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