Clean, Clear Hot Tub Water

EcoPur® Charge

EcoPur Charge Water Purification System Logo

Exclusive water purification system by Master Spas

Using the same multi-stage filtration techniques as Mother Nature, EcoPur® Charge relies on a unique blend of copper and zinc at its core that creates an electrochemical reaction to eliminate many microorganisms and remove heavy metals from the water.

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

The new EcoPur® Charge is made from Master Spas' patented filtration fabric. With this design, the fabric is wound tightly into a nautilus master core, creating a catalytic cell. The nautilus fabric cell is encased by a unique "spring core" that allows for maximum water flow and water "charging". As the hot tub water comes in contact with the EcoPur® Charge master core, a chemical reaction causes zinc and copper hydroxides to form in controlled amounts. Like Mother Nature, when controlled releases of copper and zinc oxides are carried into the filtered spa water, they kill bacteria and create a hostile environment for algae and fungal growth.


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.
