Eco Pur Water Purification

Eco Pur Water Purification System Logo

We learned a long time ago that hot tubs are meant to enjoy and not to take care of. That’s why we developed our unique, patented EcoPur® Filtration System to take the work out of it and keep the enjoyment in your everyday hot tub use. Our filtration system consists of dual filters* including our proprietary EcoPur and our state-of-the-art Corona Discharge Ozone Injection System. Rest assured that your Master Spa is built to be ready for you at any time while limiting any time-consuming hassles of taking care of it.


Mast3rPur™ Water Management System

Mast3rPur Water Management System logo

The synergistic blend of three proven natural sanitizers provides water quality and spa care not found in any other spa, including salt systems. The Mast3rPur™ Water Management System dramatically reduces harsh chemical consumption, like chlorine, while removing many heavy metals and chloramines for water that looks crystal clear, smells fresh and has a silky feel. This innovative, exclusive benefit is due to the power of three elements: ozone, UV-C light and copper and zinc.

The Three Mast3rPur™ Elements


Ozone helps kill microorganisms in the Mast3rPur Water Filtration

When absorbed in water, ozone kills pathogens and microorganisms, destroys organics and oxidizes non-organic contaminants.


Mast3rPur Water Management uses UV-C light to break down chloramines

When germicidal UV-C light is exposed to water, it inactivates microorganisms and breaks down chloramines.


Copper and Zinc help remove heavy meatals from your hot tub water

The unique combination of copper and zinc in the patented EcoPur® filters creates an electro-chemical reaction to eliminate many microorganisms and remove heavy metals such as lead and mercury.

Relax better knowing that your water is clean
Enjoying a hot tub is safe for the whole family

Each of the three elements are proven effective water management tools, but when they are combined, their synergy makes them dramatically more effective through a chemical reaction known as Advanced Oxidation Process (AOP). AOP is superior to other systems, because it produces powerful hydroxyl radicals that maximize disinfection and reduce chloramines fast and effectively. Clean, clear, fresh-smelling, and better feeling water is available now with less work - another innovative, exclusive benefit only available through Master Spas on most models.
