First Stage PFAS Removal Water Filter
SGS-tested media removes up to 99% of PFAS, including PFOA and PFOS, from your water, ensuring safer water for your household.
Activated carbon fiber reduces residual chlorine, VOCs, and other chemical contaminants for cleaner, fresher water.
-
Second Stage Composite Water Filter
Reduces chlorine, lead, mercury, hydrogen sulfide, heavy metals, herbicides, odors, and more for cleaner water.
For households with high TDS levels (>300 ppm), pair this filter with a water softener such as the iSpring WCS45KG to maximize filtration efficiency and extend system life.

Recommended Setup Order
Do I still need a water softener if my water is hard?
Yes. Our WGB32B-PFKS whole house water filter system does not reduce hardness. It is recommended to install a water softener, such as the iSpring WCS45KG model, before this system if your TDS level is above 300 ppm.
What contaminants can this system remove?
Turbidity, visible particulate matter, sand, silt, dirt, rust, chlorine, taste, odor, THMs, VOCs, PFAS (including PFOA and PFOS) and more.
Can I install this system outdoors?
Install indoors in a well-ventilated area, shielded from wind and rain, away from direct sunlight and heat. Consider water leakage protection. For outdoor installation, ensure insulation for frost, sun, and waterproofing for both unit and pipes.
Can I use this system if my water flow is from left to right?
Yes, you can. However, please note that the inlet/outlet marking on the system is fixed, so you will need to flip the machine head to accommodate this setup. To do this, simply unscrew the screws on the machine head and flip it.
