Cryspool Spa Filter Replacement 50 sq ft for Caldera PCD50N, Trilobal Media & Reinforced End Caps

Cryspool 07022 is a 50 sq.ft. replacement spa filter engineered to match Caldera 50/PCD50N dimensions and restore clear, well-filtered spa water.

If your spa needs a reliable, easy-to-clean cartridge that fits Caldera models and several OEM part numbers, this Cryspool replacement is shaped and sized for a direct swap. It measures 10-3/4" long with a 7" outer diameter and a 2-11/16" bottom opening, providing a full 50 square feet of filtration area. The cartridge uses trilobal fiber media and reinforced end caps to improve contaminant capture and durability while remaining compatible with common Caldera spa housings and legacy part numbers.

How does this filter match my spa’s specifications?

The Cryspool 07022 is designed to mirror the critical dimensions and connection features of Caldera 50 and PCD50N cartridges, making installation straightforward without modifications. It keeps the same semi-circular top handle geometry and bottom opening size to seat securely in standard filter chambers.

• Length: 10-3/4" for correct depth fit
• Outer diameter: 7" to match housing clearances
• Bottom opening: 2-11/16" for proper seal and flow
• Filtration area: 50 sq.ft. to maintain designed flow rate

What filtration performance can I expect?

The cartridge uses trilobal fiber media that increases surface area and traps particles more efficiently than conventional point-bond fabrics. The construction helps impurities lodge deeper in the pleats, which improves capture between cleanings and extends usable life when maintained properly.

• Trilobal fibers for enhanced particle capture
• Dense pleat structure to increase effective media area
• Reinforced end caps and pleat stability for lasting shape
• Better dirt retention compared with generic filters

How should I clean and care for this cartridge?

This Cryspool filter is engineered for thorough rinsing and periodic deep cleaning, returning near-new performance after proper maintenance. Rinse with a hose to remove surface debris and use a filter cleaner soak according to manufacturer recommendations when the pressure gauge indicates higher differential pressure.

• Rinse pleats front-to-back with steady water stream
• Soak in a proprietary filter cleaner for deep oil and scale removal
• Clean when pressure gauge reaches your spa’s recommended limit
• Regular cleaning extends life and reduces water treatment needs

Is this compatible with the OEM part numbers I’m replacing?

Yes — Cryspool lists fitment for Caldera 50, Caldera Spas, and several cross reference numbers including 1019401, PCD50N, and FC-3963. The manufacturer names and OEM numbers are used only for compatibility reference; Cryspool is an independent brand producing direct-fit replacement cartridges.
