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

Part #: FM-BB-20-0.35

This Flow-Max 20" Big Blue water filter is a 0.35 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.  0.35 micron is in the particle filtration category and cannot be seen by the human eye. The Flow-Max pleated sediment filter (FM-BB-20-0.35) 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.
