The Watts Flow-Max FM-1-40 Filter cartridges outperform wound, spun, melt blown, resin bonded and other "depth" type filter elements because our cartridges are pleated to provide increased surface area and longer life. Savings is realized with extended filter life from the 100% synthetic filter media.

Specifications:

• Sediment Filtration
• 1 Micron Nominal
• Flow Rate: 16 gpm
• Chemically resistant Pleated Polyester Filtration
• 100% Cellulose Free

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