About Filter Bags

About Filters and Particle Sizes

Filter Bags for Water

Use these bags with a filter bag housing to remove contaminants from your water line.

Long-Life Filter Bags for Water

Replace your filter bags less frequently—these have greater debris-holding capacity than standard filter bags.

High-Purity Filter Bags for Water

Also known as absolute-rated filter bags, these remove 99% of particles.

Tie-On Filter Bags for Water

A drawstring at the opening allows you to tie these filter bags directly to your pipe or hose.

Filter Bags for 5-Gallon Pails

Strain small batches of water with these bags that are sized to fit a 5-gallon pail.

Slip-On Filter Bags for Water

These filter bags wrap around pipe or hose and secure with a clamp or band.

Thread-On Filter Bags for Water

Use a threaded adapter with one of these bags to filter water from a threaded pipeline.

Filter Bags for Petroleum Oil and Organic Solvents

Use with a filter bag housing.

Filter Bags for Food and Beverage

Made of FDA-listed materials, these bags are suitable for contact with food and beverage.

Cloth, Mesh, Wool and Perforated Sheets

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.

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).

Chemical-Resistant Filter Felt

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

Ultra-Thin Filter Fabric

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

Filter Felt

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

Odor-Removing Filter Felt

Less messy than carbon granules, this carbon-coated felt removes odor from liquids and air.

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 PTFE Adhesive-Back Discs

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

High-Capacity Plastic Filter Housings with Cartridge for Drinking Water

High-Capacity Plastic Filter Housings
with Cartridge for Drinking Water

Also known as reverse osmosis water filters, these include several cartridges to reduce odor, rust, sediment, and lead from drinking water, as well as a tank to store filtered water.

Muslin Cheesecloth Fabric

Use for lining, cleaning, straining, and polishing.

Filter Sleeves for Underground Perforated Drain Pipe

Protect perforated underground drain pipe from clogging.
