The original WELTICO C3 cartridge measures 386 mm in height and 180 mm in diameter. Some compatible cartridges may have a different height, so these dimensions should not be considered universal across all equivalent brands. The top of the filter features a handle, while the bottom has a 50 mm opening.
Regular maintenance is essential for effective filtration and clean water. Rinse your filter cartridge regularly, depending on how often you use your hot tub. Even with proper maintenance, a filter cartridge will eventually wear out and should be replaced every 6 to 12 months or sooner if damaged.
This filter is designed for both swimming pools and hot tubs. However, compatibility depends on your existing filtration system. Check your cartridge's part number before choosing a replacement.
Check the height, outside diameter, and bottom opening of your existing filter. The original WELTICO C3 cartridge measures 386 mm in height and 180 mm in diameter, but compatible alternatives may vary.
If the filter pleats remain gray or brown after cleaning, if the handle or plastic components are damaged, or if the water flow in your pool or hot tub drops significantly, your cartridge may be clogged or worn out and should be replaced.
