J-275™

CLEARRAY Active Oxygen™ is Jacuzzi’s built-in water purification system — it works quietly in the background between chemical treatments, so your water stays cleaner with less manual dosing.

• Runs a two-stage process: water is first injected with a low dose of ozone, then passed under a UV-C bulb, triggering a reaction (advanced oxidation) that unlocks active oxygen
• That active oxygen keeps breaking down contaminants after treatment, pushing residue toward the filter for removal
• Jacuzzi states the system can neutralize up to 99.9% of waterborne pathogens and contaminants within seconds of exposure to the UV-C light
• Reduces the amount of chlorine needed by up to 75% compared to a chlorine-only sanitizing routine
• Standard equipment on all current Jacuzzi hot tub models, not an upgrade you have to add on

Fewer chemicals also means less chlorine smell and gentler water on skin and eyes.

Jacuzzi builds an LED-backlit waterfall into most of its hot tub collections. It’s a soft, controlled cascade positioned to flow over your neck and shoulders rather than splash into the tub.

• Backlit with LEDs so the water glows as it falls, adding a visual centerpiece day or night
• Can be switched on or off independently from the jets, so you can add or remove it from your soak whenever you like
• Named and styled differently by collection — for example, the J-300™ Collection’s “Water Rainbow®” waterfall and the J-400™ Collection’s “WaterColour™” waterfall(s)
• Beyond ambiance, the flow helps keep water circulating, moving debris and chemicals toward the filter
• Higher-end collections, like the J-LX®, pair the waterfall with an infinity-edge design for a more dramatic pour

Waterfall style, number, and placement vary by collection — check your model’s spec sheet for the exact version included.

SmartTub® is Jacuzzi’s connected hot tub platform — a hardware upgrade plus an app that lets you manage your spa remotely instead of walking out to the control panel every time.

• Adjust temperature, jets, and lighting, and lock the spa against unauthorized use, all from the SmartTub® app on your phone
• Works with voice assistants (Siri, Alexa, Google Assistant) and wearables (Apple Watch, Android Wear) for hands-free control
• Smart Heat Mode learns your usage patterns and can cut standby heating costs by up to 25%; Vacation Mode further reduces heating while you’re away
• Sends power outage alerts and includes freeze/overheat protection, plus a Power Estimator to track energy use and carbon footprint over time
• Requires a hardware upgrade purchase and is compatible with 2016-and-newer Jacuzzi hot tub models; connects over cellular rather than relying solely on home Wi-Fi

Confirm SmartTub® compatibility and any hardware cost with your dealer before assuming it’s included on a given model.
