Pleatco Replacement Spa Cartridge PAS40-F2M for New Artesian 6-D — 6 x 7.625 in, 2" MPT, High-Efficiency Filtration

The Pleatco PAS40-F2M is a genuine high-efficiency replacement spa cartridge engineered to restore clean, balanced water flow for New Artesian 6-D spas and compatible systems.

This replacement cartridge uses Pleatco’s Advanced Point Bonded media and Free Flow Core to capture finer particles, extend cleaning intervals, and maintain steady water circulation with lower operating pressure. Built to OEM-fit dimensions (6" diameter, 7.625" length, 2" MPT bottom) and designed in the U.S., the PAS40-F2M is a direct substitute for common cross-reference models like Unicel 6CH-352 and Filbur FC-0312.

How does the PAS40-F2M improve spa water clarity?

Pleatco’s Advanced Point Bonded fabric is manufactured with a higher fiber count and a uniform bonding process that traps smaller dirt and debris than conventional media. Cleaner water results from finer filtration, which reduces visible particles and improves the effectiveness of sanitizers.

• High-fiber point bonded media captures finer contaminants
• 40 sq ft media area for increased dirt-holding capacity
• Uniform pleat spacing for even dirt loading and consistent filtration

Will this cartridge maintain good flow without stressing my pump?

The Pleatco Free Flow Core features a box-ladder injection-molded design that maximizes water throughput while keeping operating pressures low. That balanced flow reduces wear on spa pumps and plumbing, extending component life and preserving circulation performance.

• Reinforced core supports stable flow under load
• Even distribution of water through the media minimizes pressure spikes
• Designed to lower motor strain compared with restrictive cores

How easy is it to clean and maintain this Pleatco spa cartridge?

Maintenance is simplified thanks to Pleatco’s media and construction: dirt releases more readily during rinsing, and the Superbond bands keep pleats separated so water and cleaners reach the full surface. Longer cycles between cleanings mean less hands-on upkeep.

• Point bonded fabric sheds trapped dirt faster when rinsed
• Superbond bands prevent pleat collapse and improve cleaning access
• SmartTrack ID on every unit for quality traceability and warranty support

Is this cartridge compatible with my spa model and other filter references?
