Donaldson Introduces Alpha-Pore™ Technology Platform for Extended Sterile Filtration Performance

Donaldson Company, Inc., a leading worldwide manufacturer of innovative filtration products and solutions, today announced Alpha‑Pore™ technology, a next generation sterile filtration platform engineered to extend filter service life while maintaining critical process performance.

Built for critical applications, Alpha‑Pore technology enables longer filter run time compared with competitive single- and dual-layer polyethersulfone (PES) membrane filters, while maintaining flow characteristics, sterility assurance, and process integrity.* The platform is designed to help manufacturers improve operational efficiency through fewer changeouts and more consistent performance over time.

Engineered for Extended Performance

Sterile filtration processes often require balancing run time with key performance parameters such as flow, differential pressure, and contaminant retention. Alpha‑Pore technology is designed to achieve all three.

By optimizing pore structure and filter architecture, Alpha‑Pore technology supports sustained performance throughout the filter lifecycle—helping maintain stable operation under challenging conditions.

Key Benefits Include:

   Up to 2.5× longer run time under controlled test conditions versus conventional PES cartridge designs*
   Validated for consistent micro-biological retention efficiency for process food and beverage applications
   Stable differential pressure profile compared to equivalent single-layer products
   Robust construction engineered to withstand up to 150 sterilization-in-place (SIP) cycles

A Platform Approach to Sterile Filtration

As a new platform within the Donaldson LifeTec™ filter element portfolio, Alpha-Pore technology is engineered to improve run time performance over traditional single- and dual-layer filters, while maintaining the filtration characteristics required for sterile applications.

"Our customers have traditionally faced tradeoffs between extended filter life and maintaining critical process performance," said Nathan Zambon, Senior Director of Product & Technology at Donaldson. "Alpha-Pore technology is designed to help overcome those challenges, enabling longer run times while supporting the sterility, flow performance, and process consistency customers depend on."
