1 Micron Flow-Max Pleated Sediment Filter
Actual: (20" x 4½")

Part #: FM-BB-20-1

This Flow-Max 20" Big Blue Water filter is a 1 micron sediment filter pleated cartridge that will reduce Cryptosporidium and Giardia Cysts to 99.9%, and filter sand, dirt, sediment and rust from your water which affect the taste and appearance.  1 micron is in the particle filtration category and cannot be seen by the human eye. The Flow-Max pleated sediment filter (FM-BB-20-1) offers excellent chemical resistance and high dirt holding capacity, all at an economical price. 100% synthetic and cellulose free.

This water filter fits most water filter housings that require standard-sized large Big Blue 20" water filters (20" x 4½"). It is compatible as a replacement filter for all 20 inch Big Blue filter housings by Culligan, Ametek, Pentek, US Filter, Plymouth Products, American Plumber, and others that use 20" x 4.5" filters. These Big Blue filters feature a higher flow rate and dirt-holding capacity than standard-sized sediment water filter cartridges.

Flow-Max filter cartridges outperform wound, spun, resin bonded and other "depth" type filter elements because our cartridges are pleated to provide increased surface area and longer life. Flow-Max filter cartridges outperform other pleated elements because our high performance filter media is systematically produced using 100% synthetic fibers, with no binders or additives to leave a residue, foam or contaminate. Our filter media is dramatically thicker than other products. For this reason, Flow-Max cartridges provide "depth" filtration.
