About Filter Bags

About Filters and Particle Sizes

Seamless

Sewn

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

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

Long-Life Filter Bags for Water

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.

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

High-Purity Filter Bags for Water

Also known as absolute-rated filter bags, these remove 99 % of particles. They provide more consistent particle removal than other filter bags and have high debris-holding capacity for a long service life. Use them with a filter bag housing to remove contaminants from your water line.

Fabric filter bags hold more debris than felt filter bags.
