Cryspool Spa Filter Cartridge 75 sq.ft. for Caldera 75 / PCD75N — Trilobal Fiber, Reinforced End Caps

Cryspool 07043 is a 75 sq.ft. replacement spa cartridge designed to fit Caldera 75 models (including PCD75N and part number 1019301) and deliver deeper, longer-lasting filtration.

This replacement filter cartridge is engineered for compatibility and improved cleaning performance. Built with trilobal fiber pleats and reinforced end caps, the Cryspool 07043 offers a larger effective area and easier maintenance than many standard point-bonded filters. It matches the length and dimensions expected by Caldera 75-series spas so you can swap it in without modification and restore efficient circulation and clearer water.

Will this filter fit my Caldera 75 spa or PCD75N model?

Yes — the Cryspool 07043 is sized to replace common Caldera part numbers such as 1019301 and PCD75N. Check your existing cartridge dimensions and top/bottom openings to confirm a match before ordering.

• Length: 14-3/4" which matches many Caldera 75 cartridges.
• Outer diameter: 7" and bottom opening: 2-11/16" for proper seat fit.
• Semi-circular handle on top for straightforward removal and installation.
• Filtration area: 75 sq.ft., matching original-flow expectations.

How does the trilobal fabric improve filtration and cleaning?

The Cryspool cartridge uses trilobal fibers that create more surface area and channels within each pleat. That structure traps finer debris and lets contaminants penetrate deeper into the pleat gaps so rinsing releases more trapped material, restoring performance.

• Trilobal fiber increases effective capture area versus standard point-bond materials.
• Pleat geometry promotes deeper contaminant lodging for thorough rinsing.
• Cleaner pleats after washing mean longer intervals between replacements.
• Durable construction resists collapse or deformation under normal spa pressure.

What routine maintenance keeps this filter performing well?

Routine cleaning and inspection are key. Rinse the cartridge when the spa’s pressure gauge reaches the manufacturer-recommended level and perform a deeper chemical soak periodically to remove oils and scale.

• Rinse with a high-pressure hose to flush pleats front-to-back.
• Soak monthly (or as needed) in a filter-cleaning solution for oils and minerals.
• Inspect end caps and pleats for damage; replace if torn or compressed.
• Rotate filters and clean more often in heavy-use or high-bather-load conditions.

Who is this replacement filter for?

This cartridge is intended for spa owners seeking a dependable, easy-to-clean replacement for Caldera 75-series cartridges (including models listed as 1019301, PCD75N, and similar). It’s a practical choice if you want a direct-fit option with improved pleat material and longer usable life than basic paper-style filters. If you manage a residential spa, want to minimize chemical and water waste by keeping filtration efficient, or simply need an affordable OEM-compatible spare, Cryspool 07043 is built to meet those needs while fitting common Caldera housings.
