Far Infrared Rocks
Enhances the purification process through its unique properties. It stimulates molecular movement, promoting the breakdown of contaminants and enhancing the removal of impurities.
Negative Ion Rocks
Attract and neutralize positively charged contaminants, effectively purifying the water. By harnessing the power of negative ions, these rocks help create a cleaner, healthier water supply.
Alkaline Rocks
As water passes through alkaline rocks, they release minerals like calcium, magnesium, and potassium, enriching the water with essential nutrients. This process not only improves the taste and odor of water but also helps neutralize acidity.
Magnetic Energy Rocks
As water flows past magnetic energy rocks, they attract and trap contaminants, resulting in purer and fresher-tasting water.
What This Filter Removes




The Alkaline filter simply returns minerals such as ionized calcium, magnesium, sodium, potassium ions, which were taken away while purifying the water.
