Cryspool CP-04072 Spa Filter Cartridge, 25 sq. ft., 2-Pack
Product description
If your hot tub uses a compatible 5 × 13 filter cartridge, the Cryspool CP-04072 offers a practical replacement in a two-cartridge pack. Its 25 sq. ft. filtration area and trilobal-fibre media are designed to capture impurities while allowing the pleated cartridge to be rinsed and reused.
Match the cartridge dimensions and compatible reference numbers to your existing filter before choosing a replacement. The reinforced end caps and bands help keep the element in position during use.
Size & fit
The CP-04072 measures 13 5/16 inches long and 5 inches across, with 2 1/8-inch openings at the top and bottom. It is listed as compatible with several replacement references, including C-4326, FC-2375, PRB25-IN, 303909, M-4326, 817-2500, R173429, 3005845, 25392 and 33521. These references make it easier to compare the cartridge with the model currently installed in your spa. Check both the reference and dimensions when selecting a replacement, rather than relying on a similar-looking cartridge alone.
Where it shines
This cartridge is suited to routine hot tub filtration, with pleated trilobal-fibre media providing the surface area to collect impurities as water passes through. The filter structure is made for cleaning and repeated use: rinse the pleats when the pressure gauge reaches its predetermined cleaning point, following your spa’s usual care routine. Regular cleaning helps maintain the cartridge’s filtering function and supports continued use.
For a replacement purchase, this gives you an alternative to choosing a cartridge solely by its appearance: you can compare its dimensions and listed reference numbers with your existing filter. The two-pack format also provides a second cartridge for your filter-care rotation. As an independently branded compatible spare, Cryspool uses other manufacturers’ names and part numbers as references, the cartridge itself is identified as the CP-04072.
