Original Watts Pack of 4 Filter (WPC0.35-975) 9.75" x 2.75" 0.35 Micron Pleated Sediment Filters - Compatible to Watts Water Quality FM-0.35-975
WPC0.35-975 Pack of 4 0.35 Micron Pleated Filters
9.75" x 2.75" synthetic pleated cartridges compatible with Watts FM-0.35-975. Washable, reusable, and engineered for superior dirt-holding capacity in whole house and RO pre-filtration applications.
Pleated design outperforms depth-style cartridges
Greater Surface Area
Pleated polypropylene media provides significantly more filtration surface than wound or spun cartridges, resulting in longer service life and higher flow rates.
Lower Pressure Drop
Synthetic pleated construction maintains lower initial pressure drop compared to depth-style filters, reducing strain on pumps and preserving system efficiency.
Washable & Reusable
Direct spray into pleats to dislodge sediment and restore flow. Reduces replacement frequency and filtration costs without compromising performance.
Cellulose-Free Media
100% synthetic polypropylene with no binders or additives that break down. Prevents foaming, filter degradation, and downstream contamination.

Direct replacement for Watts FM-0.35-975
These WPC0.35-975 cartridges are engineered as compatible replacements for Watts Water Quality FM-0.35-975 filters. Standard 10" x 2.5" housing footprint with 2.75" OD color-coded end caps. Suitable for whole house sediment filtration, reverse osmosis pre-filtration, and multi-stage water treatment systems requiring 0.35 micron sediment removal.
Replacement and cleaning schedule
Inspect & Clean
Check pressure differential. If below 25 psid, remove cartridge and spray directly into pleats to dislodge sediment. Reinstall and monitor flow.
Replace Cartridge
When pressure drop reaches recommended 25 psid changeout threshold or cartridge no longer cleans effectively, replace with fresh filter from pack.
Maximum Service Life
Replace cartridge regardless of pressure drop to maintain optimal filtration performance and prevent media degradation in high-sediment environments.
Lower Operating Cost
Washable design and pack of 4 pricing reduces annual filtration costs compared to single-use depth cartridges.
Higher Flow Rates
Lower pressure drop maintains consistent flow throughout service life without compromising sediment capture.
Superior Dirt Capacity
Pleated media holds more sediment per square inch than wound or spun alternatives, extending time between changes.
No Additive Breakdown
Synthetic media contains no binders or cellulose that degrade over time, preventing foaming and filter failure.
