Watts Whole House filters for chlorine taste, odor, and sediment removal. 
Our PWBWGAC Series activated carbon filters are designed for 
residential and light commercial applications up to 15 gallons 
per minute. Watts activated carbon filters are highly popular 
because they correct a wide range of water quality issues  
by removing chlorine, taste, odors, organic chemicals, and 
sediment.
Activated carbon has been used in the treatment of drinking 
water for over 2000 years. It was found that charred wood 
products aided in improving the quality of drinking water.

We use Aquasorb® coconut shell activated carbon. This is a 
high-activity granular activated carbon manufactured by steam 
activation of select coconut shell charcoal. Its high microporosity makes it particularly well suited for the adsorption of 
low molecular weight compounds at very low concentrations. 
It is also ideally suited for the removal of oxidizing agents such 
as chlorine from drinking water. Another important feature of 
this activated carbon is its superior mechanical hardness which 
helps ensure a clean, low dust product with an exceptionally 
long life span. 
Pro SE Series Control Valve
Manufactured from high-tech materials, the Pro SE Series 
control valve has been engineered and tested to withstand 
the equivalent of 27 years of uninterrupted daily use. The proprietary design features a Teflon 
through a series of seals and spacers. This seal/spacer and 
piston configuration is the most reliable design in control valve 
technology. The valve features an electronic control for easy 
programming.
