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.

Long-Life Filter Bags for Water


Seamless	Sewn

Replace your filter bags less frequently—these have greater debris-holding capacity than standard filter bags. Use them with a filter bag housing to remove contaminants from your water line.

Seamless—Seamless filter bags are made of extra-thick material to trap large amounts of debris. They provide more uniform filtration than filter bags with a seam and trap very fine particles that can pass through the pinholes in a seam.

Sewn Seam—Sewn filter bags are made of two separate bags; the inside bag traps large particles and then the outside bag traps small particles.
