The Watts Flow-Max FM-BB-10-5 Filter Cartridges outperform wound, spun, melt blown, resin bonded and other "depth" type filter elements because the chemically resistant pleated polyester media provides increased surface area and longer life, and are cleanable on filter of 5 microns and up.

Features:

• Cleanable Filter
• Sediment Filtration
• 5 Micron Nominal
• Chemically Resistant Pleated Polyester Filtration
• 100% Cellulose Free

CONSUMER NOTE: All Watts branded cartridges will have blue end-caps with the micron rating.
