VEVOR C900 Pool Filter Cartridge Replacement — 90 sq.ft. 17 3/8" L x 8 15/16" OD, 50-micron

VEVOR’s C900 pool filter cartridge is a direct-fit replacement for Hayward C900/CX900RE, Pleatco PA90, and Unicel C-8409 cartridge systems, delivering 90 sq.ft. filtration in a durable, easy-to-clean design.

If your inground pool or spa uses a 90-square-foot cartridge filter, swapping in the VEVOR HYP-90-4 restores efficient particle capture and extends time between cleanings. This cartridge matches the common C900 footprint—overall length about 17 3/8" and outer diameter near 8 15/16"—so installation is straightforward. Built with trilobal filtration fabric and a reinforced core, it balances fine-filtration performance with structural resilience under typical pump pressures.

How does this cartridge improve water clarity for daily pool use?

The VEVOR C900 uses a trilobal fiber media rated around 50 microns to trap a wide range of debris, from hair and pollen to fine dust. That finer capture prevents particles from recirculating and helps downstream sanitizers work more efficiently.

• Trilobal fabric for increased surface area and better particle entrapment
• Approximately 50-micron filtration precision for fine debris
• 90 sq.ft. media area to maximize dirt-holding capacity

Will this cartridge fit my existing Hayward or Pleatco filter housing?

Yes—this replacement is designed to be compatible with Hayward C900, Hayward CX900RE, Pleatco PA90, and Unicel C-8409 style housings. Dimensions and end-cap geometry follow the common C900 specifications to ensure a snug, leak-free fit in most 90 sq.ft. cartridge systems.

• Overall length: about 17 3/8" (L)
• Outer diameter: roughly 8 15/16" (OD)
• Manufactured to match common C900/CX900RE and PA90 form factors

How durable and maintainable is the VEVOR HYP-90-4 cartridge?

The cartridge combines a reinforced internal core and molded end caps to resist deformation from pump pressure and backwashing stress. Routine maintenance is simple: rinse with a hose to remove trapped debris, and replace when media shows wear or permanent staining.

• Sturdy inner core for structural stability under flow
• Molded end caps to maintain seal integrity and alignment
• Reusable media—fast rinse cleaning extends service life

Is this cartridge certified and safe for residential pools and spas?

The VEVOR C900 replacement is built from EPA-certified materials suitable for contact with pool and spa water, aiming to meet everyday safety expectations. While not a sanitizer, the cartridge captures solids that otherwise consume chemical sanitizer capacity, supporting overall water management.

• EPA-certified construction for safe material use
• Compatible with hot tubs, inground pools, and cartridge filter systems
• Supports efficient pump flow and balanced backpressure

Who this is for: pool and spa owners with a 90 sq.ft. cartridge filter who need a reliable, cost-effective replacement that fits Hayward C900/CX900RE, Pleatco PA90, or Unicel C-8409 housings. It's a practical option for homeowners, maintenance contractors, and rental property managers seeking improved debris capture, easy cleaning, and a durable cartridge design that supports normal pool pump operation.
