Alkegen has developed a next‑generation fiberglass filtration material engineered to deliver high water‑repellency performance without the use of added per‑ and polyfluoroalkyl substances (PFAS).

The innovation supports our broader objective of offering safer, more environmentally responsible materials while maintaining the high durability, efficiency, and mechanical robustness expected of advanced filtration products.

The new material incorporates a proprietary chemical composition applied in flat‑sheet form, eliminating the need for additional PFAS‑based treatments.

A comprehensive evaluation program was undertaken by Alkegen’s Research and Development Team to validate its functional performance.

Testing confirmed that the material retains full water‑repellency properties, demonstrates stable interactions with commonly used sealants and adhesives, and meets established filtration performance expectations, including quality factor, particle‑capture efficiency, pressure drop, and mechanical integrity.

Performance was assessed at both the flat‑sheet level and within fully assembled filters—specifically panel and V‑bank configurations—tested according to EN1822/ISO 29463 and ISO 16890 standards.

Filters utilizing conventional PFAS‑containing fiberglass material served as benchmark comparators, enabling direct validation that flat‑sheet performance is reliably translated to final filter assemblies.

This no‑PFAS‑added fiberglass media is now commercially available and designed to support manufacturers seeking high‑performance filtration materials with improved environmental and human‑health profiles.
