High-capacity replacement cartridge designed for Jacuzzi and Cal Spa systems that accept 6-3/4" x 15-1/2" pleated filter cartridges with 2" SAE end caps (Handlex 2" SAE). This 52 sq ft cartridge offers a large filtration area for improved clarity and longer service intervals compared with smaller spa cartridges.

• ✅ 52 sq ft pleated filter media for effective particle capture
• 🧼 Anti-microbial-treated media helps limit microbial growth on the cartridge surface
• 📏 Dimensions: 6-3/4" diameter x 15-1/2" length
• 🔩 End caps: Handlex 2" SAE (fits spas that use 2" SAE-type connections)
• 🔁 OEM-style replacement fit for many Jacuzzi and Cal Spa spa models — confirm fitment before purchase

Why this cartridge: The larger 52 sq ft surface area gives improved dirt-holding capacity and can help maintain clearer water with less frequent cleaning. Anti-microbial treatment provides an additional hygiene benefit for spa environments.

Installation tips:

• Turn off pump and power before servicing the filtration system.
• Remove the filter housing cover, slide out the old cartridge and inspect end caps for wear.
• Install the replacement cartridge ensuring the 2" SAE end caps seat correctly and the cartridge is centered in the housing.
• Restore power and run the pump, check for proper flow and leaks.

Care & maintenance: Rinse the cartridge with a garden hose after each heavy use. For deep cleaning, soak in a cartridge cleaning solution per the cleaner manufacturer’s instructions, then rinse and allow to fully dry before reinstalling. Replace the cartridge when flow is reduced or when the media shows signs of irreversible wear or damage.

Fitment & compatibility: Always verify physical measurements and end-cap style against your existing cartridge or spa owner’s manual. If uncertain, compare part numbers or contact the spa manufacturer or dealer to confirm compatibility.
