Mast3rPur™ Water Management System

Mast3rPur Water Management System logo

A hot tub is meant to bring enjoyment to your daily life — not just another thing that needs to be cleaned and maintained.

With the Mast3rPur™ Water Management System, you can enjoy fresh, clean water every time you open the cover with less work and fewer chemicals compared to other brands.

The cutting edge system takes advantage of three sanitation methods — ozone, UV-C light, and a combination of minerals via the EcoPur® Charge filtration. The result is a more effective water care solution than any other system on the market. The combination of these three natural sanitizers supports overall water quality and reduces the amount of harsh chemicals needed to maintain optimal water balance.

Through the Advanced Oxidation Process (AOP), Mast3Pur quickly rids water of contaminants, chloramines and microorganisms with help from each of the three natural sanitation methods. AOP produces powerful hydroxyl radicals that maximize disinfection and reduce chloramines; producing clean, clear, sanitized hot tub water.

Mast3rPur works in unison with the QuietFlo Water C1are System™. The 24-hour circulation pump continues to filter and clean the water even when the hot tub is not in use. With QuietFlo, a typical 7-foot hot tub can have complete filtration every 11 minutes. The synergy of the three elements combined with continuous circulation creates a simplicity and efficiency in water sanitation that is unmatched.

The result is cleaner water with less chemicals, ensuring that your hot tub is ready when you are.

Mast3rPur™ Sanitation Elements


Ozone sanitation helps kill microorganisms in hot tub water

When absorbed into hot tub water, ozone kills pathogens and microorganisms, destroys organic contaminants and oxidizes non-organic contaminants.


UV-C light improves hot tub water sanitization

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


Copper and zinc naturally sanitize hot tub water

The unique combination of copper and zinc in the patented EcoPur filters creates an electro-chemical reaction that eliminates many microorganisms and removes heavy metals, such as lead and mercury.
