Clean, Refreshing Water

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 at its core that creates an electrochemical reaction to eliminate many microorganisms and remove heavy metals from the water.

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.

ecopur charge core

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 swim spa 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.

Every Michael Phelps Signature Swim Spa by Master Spas also features an advanced Ozone system that kills pathogens and microorganisms, destroys organic materials, and oxidizes non-organic contaminants to keep your water clean and refreshing every time you use your swim spa.
