Watts - WPC Series - 10"x4.5" Pleated Sediment Filter
10"x4.5" Pleated Sediment Filter
Washable, reusable pleated polypropylene cartridge with superior dirt-holding capacity and low pressure drop. Available in 0.35, 1, 5, 20, and 50 micron ratings for whole-house, well, and commercial applications.
Engineered for Performance and Longevity
Pleated Design
More surface area than wound or spun cartridges means greater dirt-holding capacity and longer service life between changes.
Low Pressure Drop
Maintains higher flow rates with lower initial pressure drop compared to depth-style filters, reducing strain on pumps and systems.
Cellulose-Free Synthetic
Pure polypropylene media with no binders or additives that can break down, foam, or degrade over time. Chemical-resistant and durable.
Washable & Reusable
Cartridges rated 5 micron and up can be rinsed and reused multiple times, reducing replacement costs and waste.

Direct Replacement Models
The Watts WPC Series replaces these Watts FlowMax models: FM-BB-10-0.35, FM-BB-10-1, FM-BB-10-5, FM-BB-10-10, FM-BB-10-20, and FM-BB-10-50. Fits all standard 10-inch Big Blue filter housings with 4.5-inch diameter cartridge cavities.
Service Schedule
Replace or Clean
Cartridges rated 5 micron and up can be rinsed and reused. Replace 0.35 and 1 micron cartridges when pressure drop reaches 25 psid.
Pressure Monitoring
Check differential pressure regularly. If pressure drop exceeds 25 psid or flow rate decreases noticeably, clean or replace the cartridge.
Housing Inspection
Inspect filter housing and O-rings during cartridge changes. Replace worn seals and clean housing interior to maintain system integrity.
Whole-House Ready
Ideal for residential, well water, and commercial sediment filtration at the point of entry.
Lower Operating Costs
Washable design and longer service life reduce the frequency and cost of filter replacements.
Easy Installation
Drop-in replacement for standard 10" Big Blue cartridges. No adapters or modifications required.
Watts Quality
Individually wrapped for purity and backed by Watts engineering and manufacturing standards.
