Compare sizes and materials to choose the right filter bag for straining liquids in your application.

Filter Bags for Water


Seamless	Sewn

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

Seamless—Seamless filter bags provide more uniform filtration than filter bags with a seam. They trap very fine particles that can pass through the pinholes in a seam.

Felt—Felt filter bags have higher debris-holding capacity than mesh filter bags.
