PFAS-Free ePM1 & MERV 13–14 Filter Media

High Mechanical Efficiency. Low Resistance. Built for a Post-PTFE Market.

In modern HVAC systems particularly in commercial buildings and data centers pressure drop is not just a specification. It is an energy cost. Every additional Pascal translates into higher fan energy consumption and long term operating expense.

At the same time, fine particle standards continue to tighten.

Historically, many high-performance solutions have relied on PTFE membranes or heavily electrostatically charged media to balance efficiency and airflow. Regulatory pressure around PFAS and fluorinated materials is increasing globally.

That model is becoming harder to sustain.

The Engineering Challenge

Achieving high air flow ePM1 60%-80% and MERV 13-14 performance typically requires one of two approaches:

• Add electrostatic charge to boost capture

• Use control pore structure filter media for mechanical capture(PTFE etc)

Both approaches introduce risk:

Electrostatic charge can degrade under humidity, discharge events, or aging, FIber glass introduces high pressure drop.

PTFE introduces regulatory exposure and sustainability concerns.

The challenge is delivering fine particle efficiency mechanically without increasing pressure drop.

The Nanofiber Approach

Matregenix has developed a PFAS-free electrospun nanofiber media designed to address this problem structurally rather than chemically.

Representative performance data:

The fine fiber architecture enhances interception and diffusion, increasing intrinsic mechanical capture while maintaining open airflow pathways.

Importantly, the media retains meaningful efficiency after IPA discharge testing demonstrating that performance is not purely charge-driven.

This improves reliability in real-world HVAC environments.

What This Enables for Market

This is where the value becomes clear.

Instead of choosing between compliance and performance, manufacturers gain both.

Instead of trading airflow for efficiency, they preserve energy performance.

Instead of relying on charge stability, they leverage mechanical structure.

The media is engineered for integration into:

• Pocket filters/ Bag filters (you can search epm 1 bag filters pics)

• Commercial HVAC platforms

• Data center air handling systems (add some pics)

For data centers in particular, where airflow consistency directly impacts thermal management and uptime, balancing resistance and efficiency is critical. This media supports that balance.

A Practical Path Away from PTFE

PTFE has long been used to achieve fine particle control with low resistance. But the regulatory and reputational risks surrounding fluorinated chemistry are rising.

This PFAS-free nanofiber platform offers a scalable, roll-to-roll compatible alternative  allowing manufacturers to transition without redesigning entire product lines.

The value proposition is not just “PFAS-free.”

It is:

A structurally engineered solution that delivers ePM1-level performance, low pressure drop, and discharge resilience without fluorinated chemistry.

That combination is what enables forward looking filtration platforms.
