The Bag is an innovative, welded filter bag with a durable non-stitched seam. It has a 180 micron mesh, is resistant to bleach, caustics, and acids, and comes with a convenient reseal able locking closure. It is available in a convenient 5 x 10 size. It is ideal for all filtration products and has an exceptionally long life. Unlike stitched seams, welded seams are not subject to degradation from exposure to bleach, caustics, acids, or other harsh environmental exposure likely to take place during regeneration of filter media.
