Questions to Ask Before Buying a PFAS/Forever-Chemicals Removal System

Key Questions to Ensure Your PFAS Removal System Is Effective and Reliable

Protecting your water supply from PFAS and other long-lasting chemicals requires careful selection of the right treatment system. Not all systems provide the comprehensive, targeted removal needed for these persistent contaminants. To make an informed purchase, it’s important to ask detailed questions about the system’s components, configurations, and capabilities. Here’s a guide to the essential questions you should consider before investing in a PFAS removal solution.

What Are the Main Components and How Do They Work Together?

A complete PFAS removal system generally includes multiple integrated units designed to work in concert:

• Whole-House PFAS-Selective Media System: Contains a media that specifically targets short- and long-chain PFAS compounds, capturing these chemicals more effectively than standard filtration media.
• Catalytic Carbon Filter: Addresses chlorine and chloramine residuals while improving taste and odor, helping to protect the integrity of downstream treatments.
• Under-Sink Reverse Osmosis (RO) System: Provides a final stage of water polishing at the tap, removing remaining contaminants for drinking water quality.

When evaluating a system, confirm that these components are included, properly configured, and designed to work together as a complete, integrated solution for PFAS removal.

What Questions Should You Ask About the Media and Its Effectiveness?

Since PFAS compounds are complex and varied, it’s important to inquire about the media used in the system:

• Is the media specifically designed to target PFAS compounds, including both short-chain and long-chain varieties?
• Has the media been tested to reduce a specified list of target chemicals, such as PFOA, PFOS, and others?
• Does the system include a bypass feature or control valve that allows easy maintenance or media replacement?

What Are the Physical and Functional Specifications to Confirm?

Beyond the media itself, verify the system’s physical and operational specifications:

• Is the treatment tank rated for steady flow and proper contact time to ensure chemical reduction?
• Does the system incorporate a high-grade catalytic carbon component for chlorine and organics?
• Is there a separate, dedicated reverse osmosis stage for final polishing of drinking water?
• Are the units designed as complete, factory-matched systems, with all necessary connections and bypass options included?

What Maintenance and Monitoring Capabilities Should You Expect?

Effective PFAS treatment often requires ongoing maintenance and monitoring:

• Does the system include features that simplify media replacement or service procedures?
• Are there indicators or control mechanisms to monitor performance and alert for media or filter changes?
• Is there documentation to guide routine maintenance to keep the system functioning as designed?

Why Asking These Questions Matters

Making sure that a PFAS removal system contains the right components, media, and configurations is essential to achieve reliable, long-term protection against these persistent chemicals. By addressing these questions, you can better understand the capabilities of the system and confirm it’s designed for comprehensive, targeted, and consistent removal of PFAS compounds, providing peace of mind for your household water quality.

A Realistic Maintenance Schedule

Regular maintenance is essential to ensure the effectiveness of your PFAS removal system throughout the year. Monthly checks should include inspecting the pre-filters and confirming they are clean and functioning properly. It's also advisable to monitor the system’s pressure gauge, ensuring optimal performance and identifying potential clogs. Every six months, consider replacing the pre-filters to maintain efficiency. Additionally, an annual service check by a qualified technician is recommended to assess the overall performance and replace any essential components. Following this schedule will help you achieve reliable PFAS removal and safeguard your water supply.

Sizing the System to the Household

Choosing the correct size for your PFAS removal system is crucial for meeting household water demands effectively. Consider the number of residents and their peak usage times, such as mornings when multiple taps may be in use. A larger family may require a system with a higher capacity to ensure consistent water quality during high-demand periods. Typically, systems are designed based on gallons per minute (GPM) rates; therefore, it's important to assess your household's specific needs. Ensuring the system is appropriately sized will help deliver reliable filtration and protect your water supply from contaminants.
