Swimara Pool Filter Cartridge Hayward C1200 Replacement — 120 sq ft, 5 oz/sq yd Trilobal Media

Swimara Ultra Series replacement cartridge fits Hayward C1200 housings and delivers 120 sq ft of heavy-duty filtration for residential pools.

This cartridge is built to substitute factory Hayward C1200 cartridges and compatible models from Waterway and other manufacturers, offering a denser 5 oz/sq yd trilobal filter media designed for pools that see frequent use or seasonal fine debris like pollen. The unit’s dimensions and connection style match common C1200-type filters, and its reinforced end caps, core, and pleat bands help the cartridge hold shape under repeated cleanings.

How does this cartridge capture very fine debris?

The Swimara uses heavy-duty trilobal fiber media that increases surface area and mechanical trapping of particles, letting it retain much smaller solids than coarser materials. The denser 5 oz/sq yd construction is intended to perform well in high-pollen seasons or heavily used pools where finer suspended debris is more common.

• Trilobal fibers designed to trap particles down to about 10 microns
• 120 square feet of pleated media for extended dirt-holding capacity
• Heavier media reduces the frequency of deep cleans in demanding conditions

Will this fit my Hayward C1200 or equivalent filter?

This replacement matches the common C1200 footprint: approximately 8-15/16 in. outer diameter, 23-1/4 in. length and 4 in. open ends. It is specified to replace Hayward CX1200RE and PA120 models and many Waterway equivalents, but always verify dimensions and clearances before ordering to ensure a precise fit.

• Dimensions: 8-15/16" OD × 23-1/4" L, 4" open ends
• Cross-references: CX1200RE, PA120, C-8412, FC-1293
• Waterway codes compatibility: 817-0125NB and PWWCT125

How durable is the construction and how should I maintain it?

The cartridge features molded polyurethane end caps, a reinforced polypropylene core and pleat-retaining bands to help the pleat pack resist deformation over time. For longevity, depressurize the system and rinse the cartridge top-to-bottom; inspect more frequently during heavy pollen or peak season. Clean when system pressure rises noticeably above the clean baseline—Hayward-type guidance suggests around 7–10 PSI increase for similar setups.

• PU end caps for secure seating and leak resistance
• PP core and pleat bands stabilize the heavier pleat pack
• Rinse top-to-bottom after depressurizing; inspect during heavy use

Is this cartridge certified or recommended for demanding residential use?

The Swimara Ultra Series cartridge is built with heavier 5 oz/sq yd media and is certified to NSF/ANSI 50, aligning with expectations for residential pool filtration where higher flow and frequent debris loading occur. It’s designed for owners who want a more robust replacement media compared with lighter-duty cartridges.

• NSF/ANSI 50 certification for pool use applications
• Designed for high-use residential pools and seasonal debris challenges
• Heavier media for extended service life between cleanings

Who is this for: Pool owners with Hayward C1200 housings or compatible Waterway systems who want a heavier-duty replacement cartridge that captures finer particles and stands up to frequent cleaning cycles. Choose this cartridge if you need 120 sq ft of filtration area, reinforced construction to resist pleat collapse, and a product matched to common C1200 replacement codes and dimensions.
