Savener Hot Tub Spa Filter Cartridge 6CH-47 47 sq ft 2-Pack — Trilobal 50-Micron, ABS End Caps

Savener 6CH-47 replacement spa filter cartridges are 9" x 6" pleated cartridges with 47 sq. ft. of trilobal filtration surface, sold as a 2-pack to restore clear, debris-free hot tub water.

These cartridges fit common spa models that accept the 6CH-47 / FC-0315 form factor and are engineered to trap fine particles while resisting deformation. Constructed with reinforced ABS end caps and a dense trilobal fiber media, the Savener filter balances flow and filtration so your pump runs efficiently and your water looks cleaner between cleanings. The cartridge comes certified to NSF/ANSI 50 materials safety standards and includes practical features like a molded top handle and a 1-1/2" tapered male thread bottom for straightforward installation.

How do these filters improve hot tub water clarity?

The filter's trilobal fiber structure increases surface area and adsorption, capturing a wide range of debris from hair to sand. A dedicated 50-micron layer helps remove fine particles, reducing cloudy water and reducing the load on chemical sanitizers.

• 47 sq. ft. pleated media provides large filtration area
• Trilobal fibers capture more particles than standard fabrics
• 50-micron high-efficiency layer targets fine sediment
• Durable end caps maintain shape under flow

Will this cartridge fit my spa that lists Unicel 6CH-47 or Filbur FC-0315?

Yes—this Savener cartridge is designed as a compatible replacement for Unicel 6CH-47, Filbur FC-0315, PTL47W-P4 and related part numbers. The dimensions and thread type match the common 6CH-47 reference to ensure a proper fit in most systems using that standard cartridge size.

• Length: 9" and outside diameter: 6" for dimensional match
• Top opening: molded handle for easy removal and placement
• Bottom: 1-1/2" male tapered thread to match typical housings
• Sold as a 2-pack for simultaneous replacements or spares

How do I clean and maintain these cartridges for best life?

Rinse the cartridge frequently with a garden hose to dislodge trapped debris and preserve the pleats; periodic deep cleaning with a filter cleaner helps remove oils and scale. Regular rinsing extends usable life, but replace cartridges when pleats show wear or flow noticeably decreases.

• Rinse weekly under clean water for routine maintenance
• Use a filter-cleaning solution for monthly deep cleanings
• Replace when pleats are torn, compressed, or flow reduces
• Do not backwash—this cartridge is not designed for backwashing

What safety and quality assurances does Savener offer?

Materials used in the cartridge have been tested for pool and spa safety to meet IAPMO NSF/ANSI 50 standards, minimizing risk of harmful leaching during long-term water exposure. Savener manufactures, warehouses, and supports its filters domestically and provides a six-month return policy for quality concerns.

• IAPMO-tested to NSF/ANSI 50 for material safety
• Reinforced ABS end caps and robust pleat cores for durability
• Company-backed service and six-month returns for defects
• Clear product labeling and compatibility references included
