• Vortex skimmers skim surface contaminants such as body oils and lotions then direct it into them into the filter cartridges which trap contaminants and particulates.
• Water is also drawn from the footwell through a safety suction fitting.
• Water is forced upward through the filter to trap debris that may settle at the bottom of the spa, thus, mixing, recirculating and filtering all the water, surface to floor. This translates to circulating about 24,000 gallons of water daily! (Based on using a MP160 pump.)
• Filtered water is drawn into primary jet pump.
• Water is simultaneously routed through the high-flow heater assembly.
• Ozonator’s high-output, energy efficient design converts oxygen into activated ozone gas. Mazzei® injector mixes ozone with water which is then introduced into the mixing chamber.
• Bacteria and other contaminants are oxidized before ozone converts back to oxygen.
• Residual ozone and converted oxygen are reintroduced into the spa water through a dedicated fitting for maximum efficiency.
• Water passes through the in-line sanitation system and is treated with natural minerals and bromine before reentering the spa.

The rules of the game have changed – I no longer need a chemistry degree to care for my spa water – Marquis’ Constant­Clean™ water management system and SmartClean™ filtration system takes care of it for me so I have more time for fun! I love the feel of truly clean water.

Marquis’ ConstantClean water management system is like cruise control for my spa – I just set it and practically forget it for up to a month. My spa is ready whenever I want to soak. First, Marquis' exclusive ozone system effectively destroys unwanted elements 3000 times faster than sanitizer alone. Second, the in-line sanitation system uses natural minerals and bromine cartridges to treat my water so it’s safe and clean without unpleasant odors or skin irritation.

SmartClean™ software knows when I’ve used the spa and automatically triggers a cleanup cycle after my soak – that’s smart! Plus, I can adjust filtration cycles according to how often I use my spa or even if I’m on vacation. I also run it during off-peak hours to conserve energy costs. Marquis’ Vortex skimmer system filters 100% of my water from the spa floor to surface 60 to 160 times a day depending on the spa model. This dramatically reduces the need for surface cleaning or vacuuming. Marquis’ clean obsession pays off with lower maintenance and energy costs. I can enjoy my spa life!
