Swim Spa Features

H2X Fitness Swim Spas by Master Spas are built with innovative features that make it easier to enjoy and maintain your backyard pool alternative.

Standard Features:

VIP Technology

We want you to get the most out of your swim spa experience. That's why we designed the Velocity Injector Plate (VIP) Technology for H2X Fitness Swim Spas.

H2X Trainer models feature four air-injected VIP jets that create a smoother flow of water than traditional jetted swim spas. The water offers resistance so that you can enjoy a continuous exercise experience whether you swim, run, or walk.

The unique design of the plate helps to control turbulence and the flow of water. By changing the way the water is released into the swim spa, you will experience a current that’s smoother, more efficient, and powerful.

How It Works

The Velocity Injector Cones, along with the water flowing through the jets, help to create negative pressure around the perimeter of the jet face allowing water to be pulled through the front grill, into the main water stream.

AquaSpeed VSP

Six airless VIP jets create a smooth, wide current of water ideal for swimming and exercise. Enjoy greater visibility while having more control over your swim spa experience. With 25 speed settings, you can turn up the tempo for an interval workout or dial it in for endurance efforts. Available on Challenger Series swim spas.

For international customers, H2X Challenger models feature a seven-speed water current system.

EcoPur Charge Water Purification

You want to spend your time enjoying your swim spa, not worrying about water care. An exclusive filtration system, the EcoPur® Charge Master Core Technology makes maintaining your swim spa’s water easier. EcoPur Charge relies on a blend of copper and zinc to create an electro-chemical reaction that eliminates many micro-organisms and removes heavy metals. Using EcoPur® Charge filtration reduces the amount of chemicals needed, saving you money each month and protecting the swim spa’s plumbing and equipment. Read More

Energy Efficient

Master Spas designed H2X Fitness Swim Spas to be energy efficient so that they can be used year-round, no matter the weather. Using an environmentally friendly foam insulation, H2X Fitness Swim Spas are among the most energy efficient in the industry. The insulation, which is mold and mildew resistant, locks in heat and reduces energy costs. Every swim spa is built to not only meet but to exceed the stringent California Energy Commission efficiency standards.
