PFAS Concerns in Southeastern Pennsylvania
If you live in Southeastern Pennsylvania, chances are you have heard growing concerns about PFAS in drinking water. These “forever chemicals” have been detected in municipal supplies and private wells across the region, and many homeowners are asking the same question:
How do I reduce PFAS in my water without adding complexity, maintenance headaches, or major plumbing changes?
One of the newest solutions gaining attention is the HomeShield whole-house water filter from A. O. Smith. Designed as a simple, high-capacity, low-maintenance system, HomeShield represents a new generation of filtration technology aimed at PFAS reduction, chlorine removal, and overall water quality improvement, all without requiring power or a drain.
Why PFAS Is a Growing Concern in Southeastern Pennsylvania
PFAS, short for per- and polyfluoroalkyl substances, are man-made chemicals used for decades in firefighting foam, manufacturing, and consumer products. They are known for being extremely persistent in the environment and in the human body.
According to the Environmental Working Group, PFAS contamination has been identified in thousands of water systems nationwide, and exposure has been linked to potential health concerns that continue to be studied.
A New Approach to PFAS Reduction at Every Tap
Traditional water filters often focus on a single faucet or appliance. While point-of-use filters can be effective, they do not address water used for bathing, showering, cooking, or laundry.
The U.S. Environmental Protection Agency explains that whole-house treatment systems are designed to address contaminants at the point where water enters the home. HomeShield is designed to treat all the water entering your home, providing consistent filtration at every tap.
NSF Certification and 500,000 Gallon Capacity
HomeShield is tested and certified to NSF standards for the reduction of certain PFAS compounds. One of its standout features is its massive 500,000-gallon filtration capacity.
For many households, this translates to years of clean water before needing service. The EPA notes that one of the biggest challenges with residential filtration is maintenance compliance. Systems like HomeShield that are easier to maintain are far more likely to continue working effectively over time.
No Power. No Drain. No Complexity.
One of the biggest reasons homeowners in Southeastern PA gravitate toward HomeShield is its simplicity. Unlike some filtration systems, HomeShield:
- Does not require electricity
- Does not require a drain line
- Does not produce wastewater
- Does not rely on pumps or control valves
