Watts-FMHC-170-0.35 Flowmax 170 Series 0.35 Micron Pleated Filter
FMHC-170-0.35 Micron Pleated Sediment Filter
High-capacity jumbo pleated cartridge engineered for Model 170 housings with extended dirt-holding capacity and reduced pressure drop
The Watts FlowMax 170 Series cartridge delivers 0.35 micron filtration with significantly greater surface area than wound or spun alternatives. Thicker synthetic media provides superior particle retention and longer service intervals, while the pleated design maintains high flow rates at low pressure drop for whole-house and RO pre-filtration applications.
Why the FlowMax 170 Outperforms Standard Cartridges
Greater Dirt Capacity
Thicker pleated media captures and retains more sediment than thin rigid alternatives, extending time between changeouts and reducing annual filtration costs
Low Pressure Drop
Increased surface area maintains higher flow rates with less resistance, allowing use of smaller housings and reducing capital equipment investment
Cellulose-Free Synthetic Media
No additives or binders that cause foaming or bacterial growth, ensuring clean water without media migration or contamination
Fine Particle Removal
0.35 micron rating captures silt, sediment, rust, and suspended particles that damage RO membranes and reduce system efficiency
Wide Operating Range
Rated for 40°F to 140°F (4.4°C to 60°C) with maximum differential pressure of 40 psi for residential and light commercial applications
Lower Total Cost
Extended service life and fewer replacements deliver lower cost per gallon filtered compared to wound, spun, or competing pleated cartridges
Housing and System Applications
The Watts FMHC-170-0.35 is engineered specifically for FlowMax Model 170 filter housings and compatible jumbo sediment housings with proprietary end caps. Ideal for whole-house sediment pre-filtration, reverse osmosis system protection, and any application requiring fine particle removal ahead of membranes, UV systems, or sensitive equipment. Works with municipal and well water supplies.
Watts has engineered water filtration components for residential and commercial systems for decades, trusted by installers who need reliable performance and consistent availability.
