FAQ

True Water™ is Jacuzzi®’s latest breakthrough in water care. Using trillions of microscopic nanobubbles filled with oxygen, it continuously lifts away contaminants and helps keep your spa water clean, soft, and inviting. Unlike traditional systems, True Water™ achieves this while being 99.9% chlorine-free, so you enjoy a more natural soak with less effort and fewer harsh chemicals.

This groundbreaking new system is available as an optional extra on the J-435™, J-475™, and J-495™.

Infrared + Red Light therapy is a revolutionary patented wellness feature built into the FX-IR seat of the J-400™ range. It combines hydrotherapy with two kinds of light: Near-Infrared light that penetrates deep into muscle tissue (especially the lower back), and Deep Red Light, which works closer to the skin to boost surface healing. The lights warm tissue and can ease tension, improve circulation, and help reduce inflammation. Together, they can enhance flexibility, relieve discomfort, and speed up post-workout recovery.

SmartTub® is more than an app – it’s a complete management system for your hot tub. From your smartphone or connected device, you can adjust temperature, jets, and lighting, set routines, and even lock the spa when not in use. SmartTub® also provides energy tracking tools and features like Vacation Mode, which can reduce standby energy use by up to 25%. Beyond convenience, it adds peace of mind by sending alerts, reminders, and diagnostic updates directly to you or your retailer. This means less guesswork in looking after your spa and more confidence that it’s always running at its best.

Every J-400™ model is engineered for year-round efficiency. Multi-layer SmartSeal™ insulation keeps the heat in, while durable ProLast® covers prevent unnecessary heat loss. SmartTub® takes things further by letting you monitor your energy use in real time, schedule heating for off-peak hours, and switch to Vacation Mode when you’re away. Together, these features help lower running costs without compromising performance, so your spa is always warm, ready, and cost-effective to run.

If you’re looking for the most premium combination of design and performance, the J-400™ Collection is worth serious consideration. The range offers different layouts and sizes to suit different homes and lifestyles — from the compact J-435™ to the spacious J-495™. Distinctive styling, advanced hydrotherapy, and innovations like the True Water™ system set it apart.

CLEARRAY Active Oxygen™

CLEAN WATER SYSTEM

CLEARRAY Active Oxygen™ technology harnesses the power of air and light to work harder and clean the water longer. It’s an advanced oxidation process that destroys contaminants and water-borne pathogens.

Hot Tub water is injected with a low-dose of ozone and mixed thoroughly. Ozonated water is then exposed to a UV-C bulb to energize the molecules. When ozonated water is treated by the UV-C rays, active oxygen is unlocked through a natural reaction called advanced oxidation.

Super-powered active oxygen destroys contaminants and water-borne pathogens to cleanse the water. The clean, clear water is then pumped back into the hot tub where it continues to clean and polish the water, breaking down the contaminants so it can be easily be removed through the filters.

All acrylic models in every collection utilise CLEARRAY Active Oxygen™ technology and multi-stage filtration

*Stages of filtration vary by collection

5-Stage Filtration Process*

STAGES 1 & 2
The surface skimming weir and ProCatch™ bag work together to clean the surface while trapping large debris for easy removal.

STAGE 3
The ProClarity® filter on the ProStream™ circulation pump helps ensure clean, sparkling water quickly by catching tiny debris and particles that other filters miss.

STAGE 4
The ProStream™ circulation pumps pulls the water through a ProClear® filter that works to clarify water even when the jets are not running.

STAGE 5
The ProClear® filter operates with your hot tub’s hydromassage pump to remove large and small particles providing the cleanest water.
