Easy to Own, Easy to Enjoy

A Michael Phelps Signature Swim Spa by Master Spas has many features making it easy to maintain — leaving more time for enjoying it.

Clean, Refreshing Water

You want to spend your time enjoying your spa, not worrying about water care. So we created EcoPur® Charge Master Core Technology – an exclusive filtration system that makes maintaining your swim spa’s water easier.

EcoPur® Charge Master Core Technology

Exclusively by Master Spas

Using the same multi-stage filtration techniques as Mother Nature, EcoPur Charge® relies on a unique blend of copper and zinc to create an electro-chemical reaction that eliminates many micro-organisms and removes heavy metals. Best of all, it is designed so your spa can be ready to use at any time, with minimal amounts of water maintenance, so you can simply relax.

Using EcoPur® Charge swim spa filtration reduces the amount of chemicals needed, saving you money each month and safeguarding your investment by protecting the swim spa’s plumbing and equipment against the corrosive effects of chlorine.
