The FPSX Filter is a validated, single-layer Polyethersulfone (PES) membrane filter designed for reliable removal of bacteria, mold, and yeast in high-purity food and beverage applications. With low protein binding and high throughput, FPSX is an excellent choice for fermented and sensitive liquid filtration.
Flushed to minimize extractables and 100% integrity tested, FPSX filters ensure consistent performance across scales and are fully compliant with FDA and EC food safety regulations.
