Evolon 100 BFE 96.7% Reusable Filter

Evolon® technology: revolutionary, unique, invented by Freudenberg
Combining a series of outstanding technical and textile properties within a single product.
Evolon® fabrics are produced using a unique textile manufacturing process invented by Freudenberg.
 
Endless bi-component filaments are spun, uniformly laid on a belt, then simultaneously split into microfilaments and entangled using high pressure water jets to create the final fabric. No solvents or chemical binders are used in the process.
 
Since 2017, building on the success of the company’s unique Evolon® product, Freudenberg Performance Materials pushes the limits of innovation by developing Evolon® New Generation. This high-tech textile is made from super-microfilaments that are half the thickness and twice the density of those used in the original Evolon®. Evolon® New Generation complements the original Evolon® by opening up entirely new applications in the fields of bedding, technical packaging and many others.
Evolon® Microfilaments and Evolon® New Generation super-microfilaments are up to 200 times thinner than a human hair, as shown by this hair placed on the surface of the fabric.
 
They are also 5 to 10 times thinner than many other microfibers, and represent a new generation of microfiber.
 
This technology is the key to the exceptional performance of Evolon® textiles.
