Key Features of Our Whole House WS1 GAC Catalytic Carbon Filter 

Contaminant Removal

Our whole house WS1 GAC catalytic filter effectively removes chlorine, unpleasant taste and odor, VOCs, pesticides, herbicides, and other harmful chemicals, including chloramine.

Durable & Long-Lasting

Our product is manufactured with high-quality materials and built with a robust design. It ensures long-lasting performance with little to no maintenance.

Easy Installation

It provides clean, refreshing, and filtered water to all fixtures throughout your home with easy installation and maintenance for a hassle-free experience.

Excellent Add-On to Restore Essential Minerals.

Reverse osmosis systems can strip healthy minerals from your water.

But you can reintroduce vital minerals, such as calcium, magnesium, and potassium, back into your filtered water to enjoy pure, healthy, and alkaline water anytime you want by adding one filter to restore essential minerals.

Benefits of Alkaline Water

Your body tends to absorb alkaline water more readily, which promotes optimal hydration. Alkaline water helps neutralize excess acidity in your body, which supports overall health and well-being. Above all, alkaline water offers antioxidant properties that help protect your cells from damage.

Core Product Features of the Whole House WSI GAC Catalytic Carbon Filter

  • Our whole house filter utilizes the power of activated carbon coconut media for effective chlorine taste and odor removal while reducing the traces of chloramine.
  • It features a patented fiber-glass reinforced tank with a sturdy design that ensures long-lasting filter performance and reliability for your home needs.
  • The automatic backwash function and water-efficient control valve allows easy maintenance and consistent water flow, making clean water easily accessible—completely hassle-free
