The certified filter bag solution

SEFAR PHARMA GMP Bags is the certified filter bag solution for the pharmaceutical and nutraceutical  industry. The design has been developed to avoid possible contamination from staple fibers coming from the needle felt.

An ePTFE microporous membrane laminated on the polyester or PTFE needle felt results in a high filtration efficiency. The high-conductivity stainless steel matrix incorporated in the antistatic version provides excellent protection against explosion (acc. ATEX).
The manufacturing process of the SEFAR PHARMA GMP Bags is compliant with EU 2023/2006 GMP. All the materials used conform to both EU 10/2011 and FDA CFR’s.

This means that the ready-to-use complete SEFAR PHARMA GMP Bags are the only filter bags existing in the market complying with EU 1935/2004.


SEFAR PHARMA GMP Bags are tailor-made, in accordance to the specific dimension and manufacturing detail required by the equipment.
