About Filters and Particle Sizes

Filter Paper Discs

Often used in laboratory testing, these discs are designed to capture tiny particles from fluids.

Filter Paper

Cut or fold this paper to the size and shape you need for liquid filtration applications.

Remove particles from water, organic solvents, petroleum, and weak alkalies.

Chemical-Resistant Filter Felt

This felt offers better resistance to acids and alkalies than standard filter felt.

With thickness similar to filter paper, this fabric provides higher flow and is more flexible than felt.

Porous PTFE Adhesive-Back Discs

Stick these discs onto breather and other circular vents to guard against water and dirt without obstructing flow.

Porous PTFE Film

Shield vents on electronic and automotive equipment, such as cell phone microphones, from water, dirt, and debris without blocking them entirely.

Porous Stainless Steel Discs

Also known as sintered filters and frits, these discs have tiny holes that trap very small particles. Discs are often used in laboratories and gas-bubbling applications (sparging).
