Unicel 5CH-752 Replacement Spa Filter Cartridge – 75 Sq Ft (Cal Spas / Coleman Style, 2" MPT Thread)
The Unicel 5CH-752 is a premium 75 sq ft pleated spa filter cartridge commonly used in select Cal Spas (and compatible Coleman-style) filtration systems. It features a bar/handle top for easy removal and a 2" male pipe thread (MPT) bottom connection for a secure, threaded fit in compatible filter housings. Replacing a worn cartridge helps restore circulation, improve water clarity, and reduce strain on spa pumps and heaters.

- Top handle for quick removal during service
- Bottom: 2" MPT threaded connection for proper seating and sealing
- Durable pleated media and rigid core designed for repeated rinsing and deep-clean cycles

Compatibility Notes
- This cartridge uses a threaded bottom (2" MPT). If your current filter has a slip (non-threaded) fitting or different thread size, you may need a different model.
- Always confirm fit by matching the OD (5-3/16"), length (16-1/8"), and 2" MPT bottom before ordering.
When to Replace
- Flow is weak or the spa struggles to maintain circulation even after cleaning
- Pleats are torn, frayed, or separating from the end caps
- The cartridge quickly plugs up again after rinsing
- End caps or the threaded connection are cracked/warped and won’t seal properly

Maintenance Tips
- Rinse the cartridge regularly (often weekly with heavy spa use) to prevent restriction and keep jets performing well.
- Deep clean every 3–6 weeks with a cartridge cleaner to remove oils; rinse thoroughly before reinstalling.
- If scale is present, degrease first, then treat for scale (never reverse the order), and rinse completely.
- Rotating between two cartridges (one in use, one drying after cleaning) can extend overall filter life and improve filtration consistency.
