Polyethersulfone (PES) Membrane Filters, PFAS-Free, 0.22 Micron, 47mm, 200/Pk

PFAS are often referred to as "forever chemicals" because of their extreme persistence in the environment. Their strong carbon–fluorine bonds make them resistant to heat, water, oil, and degradation, properties that have driven their widespread use in modern products, including:

• Food packaging and non-stick cookware
• Cosmetics and stain-resistant fabrics
• Firefighting foams
• Industrial manufacturing and surface treatments

However, their durability also poses serious challenges. PFAS have been detected in soil, air, and water systems worldwide, leading to increasing concern about their potential impacts on human health and the environment.
