Water Management

Water Management


Water so clean, it’s patented.

At D1, we believe the most important feature in your hot tub is the water. If it is not clean, crystal clear and ready to use, nothing else matters. Our exclusive water management systems utilize dedicated components to not only provide you with clean water, but also make it simple and easy to maintain. The only way to get the cleanest water in the industry is to choose a Dimension One Spa.

What is Ozone and why is it beneficial?

The hot tub ozone system is one of the most important advances in the portable spa industry. All three D1 systems have ozone generators, often called “ozonators” for short. They’re called that because they produce ozone gas; ozone is a form of oxygen.

Ozone is the natural result of a lightning strike. It produces that clean smell in the air after a thunderstorm. Ozone is also generated in the upper atmosphere by UV light, which protects us from harmful, excessive solar radiation.

The D1 ozone generator uses electricity and an ultraviolet, or UV, lightbulb to produce ozone. The lightbulb is housed within the ozonator device, which is enclosed inside your spa’s cabinet. The ozonator converts O2, oxygen, to O3, ozone.

Though ozone is a form of oxygen, it kills germs and purifies your portable spa’s water. Chlorine does the same thing, of course. However, using ozone to sanitize your water means you can reduce the amount of chlorine you use. Too much chlorine isn’t good for your hair, skin or the environment.

What is different about the D1 Ozone systems?

D1’s ozone generators do their work in a separate, virtually closed system. After your hot tub water is circulated through your hot tub’s filter, it passes through a special, sealed chamber where the mixture of water and ozone gas safely kills bacteria and viruses and breaks down lotions, oils and other unwanted substances. Impurities not trapped in the filter get safely broken down and destroyed on contact with ozone.

Ozone gas remains in its ozone gas state for a very short period of time- from a few seconds to a few minutes at most. Once it does its work, it reverts to life-giving oxygen, the kind we breathe. This process improves water clarity, maximizes spa user comfort, reduces chemical use, reduces your handling and storage of chemicals, and saves you money on the purchase of chemicals like chlorine, chemicals that you would otherwise need much more of if you didn’t have an ozonator.

Another benefit of an ozone-based water management system is that it significantly reduces or eliminates all of the following:

  • Chlorine/Chloramine Odors
  • Faded Swimwear
  • Red or Irritated Eyes
  • Foaming
  • Environmental Impacts

As long as electricity is supplied to D1’s UltraPURE system, the ozonation process takes place behind the scenes, automatically, virtually 24 hours a day, 7 days a week, 365 days a year.

ClearZone® PRO

Optional on all @Home hot tubs.

Dimension One Spas is proud to announce, ClearZone® PRO. This factory installed option is available exclusively on the @Home Collection.

ClearZone PRO is D1’s new water purification system that creates cleaner water than the competition’s best systems. This oxygen-based system utilizes UV-generated ozone to fight and oxidize water impurities 47% more efficiently than the original ClearZone system.

Many manufacturers will tell you that all ozone systems are the same, but ClearZone PRO is not your typical ozone system. An average hot tub just injects ozone into the water, hoping it finds something to burn up. The ClearZone PRO system has a Mazzei-T injector that infuses the water with ozone, allowing for a much better mix into the water. This means more of the ozone is used to clean, rather than escaping from the water. ClearZone PRO also has a contact chamber, where water is infused with ozone in a controlled environment to disintegrate organic particles. After the contact chamber there is yet another additional de-gas chamber that separates the air/ozone mix from the water and sends it to be re-injected at the ozone jet. This creates small bubbles that help to maximize the mixing and consumption of the ozone.

A ClearZone PRO system means cleaner and clearer water, less consumption of chlorine and a system that is much easier to maintain! This means less residual ozone in the spa, thus extending the longevity of your hot tub, and the softness of your skin!

UltraPURE®: The Original Eco-Friendly Water Management System

Standard on all Reflections Collection Hot Tubs
D1’s UltraPURE® Water Management System has been the industry’s premier ozone-based hot tub water management system since it was first invented and introduced by D1. It features exclusive, patented, dual-chamber ozone technology that safely and efficiently produces clean, clear, sparkling water. In addition, D1’s UltraPURE system:

  • Is the world’s first UL-approved system that ozonates water while users occupy the spa
  • Provides virtually 100% continuous filtration, processing about 10,000 gallons a day
  • Is ultra energy-efficient: It uses less electricity than a 100-watt light bulb
  • Returns 84% of the energy it uses to the spa water in the form of heat
  • Is exceptionally quiet: unlike other spa makers, D1 uses a silent circulation pump

UltraPURE PLUS®: The Power of UV Light

Standard on all Bay Collection Hot Tubs

UltraPURE® PLUS builds on the original UltraPURE® system by adding our patented germicidal Ultra Violet light to our time-tested design. By exposing the water to a specific frequency of light**, UltraPURE® PLUS destroys any germs that may have survived the mixing chamber. Now when hot tub water passes through the chamber where UV-created ozone gas is mixed with water, the ozone-treated water/gas mixture gets exposed to an additional germicidal UV light, which is in a different frequency than the one used to create ozone. As a result, if a few remaining germs or unwanted substances survive the ozone treatment, they’ll get zapped by the extra, additional germicidal.

Minimize chemical use and cost. Limit the amount of time you spend on water maintenance. Get ultra clean, crystal-clear water and peace of mind. UltraPURE® PLUS is a standard feature on hot tubs in D1’s Bay Collection.

**For the technically inclined, this magic is mostly achieved within the UV lamp itself. The lamp is made up of two types of glass, each which contains unique trace elements. These trace elements govern the frequency range of the UV light emitted. Ozone is generated at a light wavelength of around 185 nanometers while the additional germicidal is generated at a light wavelength at around 254 nanometers. Just in case you ever need this for trivia, now you know.
