Cryspool 05011 Hot Tub Filter – 20 Sq Ft, 2-Pack | PLAS Series Compatible

Cryspool 05011 Hot Tub Filter — 20 Sq Ft Filtration, 2-Pack

Meet a replacement filter designed to support consistent spa clarity. The Cryspool 05011 is built to fit a range of popular PLAS models and other 20 sq ft cartridges, offering a compact profile without sacrificing filtration surface area. With a 7-inch length and a 5-3/8-inch outer diameter, this filter sits neatly in many hot tub housings, making routine maintenance simpler between soak sessions.

Constructed with advanced trilobal fiber media, the filter captures incoming debris while boasting a robust structure for longer life. The pleated design creates more surface area for water to pass through, helping maintain steady flow even as debris accumulates. When you rinse the filter, the material deep-penetrates and loosens trapped particles, often restoring much of the original filtration behavior after a wash. Regular cleaning, aligned with your spa’s pressure gauge, helps you get the most from each filter.

Key benefits

• Advanced trilobal fiber media delivers durable filtration with a longer service life.
• 20 sq ft filtration area with a deep-pleat design supports efficient water flow.
• Sturdy end caps and pleats help the filter stay in place and resist warping during cleaning.
• Two-filter pack provides ready replacements for routine maintenance.

Compatibility and care

• Compatible with PLAS35 LA Spas, PLAS20, 5CH-203, FC-0303, FL-0303, and 20 sq ft spa cartridges.
• Easy cleaning: rinse when needed and let the filter air-dry before reuse to refresh performance.

In everyday use, spa owners with moderate to high usage may notice steadier water clarity and more consistent pump performance. The two-pack format helps reduce downtime between replacements, so you can focus on relaxing rather than shopping for parts.

Tips for best results: keep the pressure gauge in your system in mind, rinse promptly when readings rise, and clean on a schedule that matches your spa’s usage. Cryspool remains an independent brand, designed to fit a broad set of spas while delivering reliable filtration performance.
