SentryPFN™ Your Shield Against Forever Chemicals
Emerging scientific research shows that these chemicals have a very detrimental impact on human health. In 2024, the USEPA rolled out new regulations that generally limit PFAS to levels of no more than 4 ppt (parts per trillion). This standard is not effective until 2027.
A whole-house filtration system that stops PFAS in their tracks before they can reach a single faucet in your home. With high-capacity performance handling flow rates up to 20 GPM, it’s suitable for homes with 6+ bathrooms.
Designed for versatile installation along side the Bodyguard™ or Bodyguard Plus™ systems, the SentryPFN™ offers clean, PFAS filtered water from every tap. It’s a low-maintenance powerhouse – no electricity needed, no settings to adjust, and no wasted water. With a capacity of up to 400,000 gallons*, it provides long-lasting protection for homes of all sizes.
Certified Excellence in Filtration
At the heart of the SentryPFN™ is its cutting-edge technology: ANSI/NSF 61 certified, patent-pending P-Fluormer™ Media by Mycelx. This advanced filtration media meets and exceeds the EPA’s recommendations for PFAS removal technologies, which include activated carbon adsorption, ion exchange resins, and high-pressure membranes.
Made in the USA, the SentryPFN™ supports American innovation and quality. It’s backed by US Water Systems, a name Americans have trusted for years to remove chlorine, chloramine, PCBs, THMs, and many other toxins.



EPA Insights on PFAS Removal
In April 2024, the EPA established its first-ever national standard for PFAS in drinking water, setting limits at 4 ppt (parts per trillion), to be effective in 2027.
The EPA recommends three removal methods, all utilized by SentryPFN™:
- Activated Carbon Absorption
- Ion Exchange Resins
- High-Pressure Membranes
SentryPFN™ already exceeds the EPA’s 2027 standard for PFAS removal.
