Frequently Asked Questions
Is the 50282 filter compatible with my RIPTIDE or Crystal Island spa?
If your current filter is marked with the part number 50282, SC864-S, or D.03.0450, this filter is the direct replacement. It is designed for RIPTIDE and Crystal Island spas. Simply check the part number printed on your old filter before ordering. If you're unsure, our filter selection guide can help you find the right model.
How can I check if this filter fits my spa?
This filter measures 210 mm (8.27 in.) long and 137 mm (5.39 in.) in diameter. Measure your current filter when it's dry, either before installation or after removing it. If the dimensions match, the filter is dimensionally compatible with your spa. For detailed instructions, see our spa filter measurement guide.
What's the difference between part number 50282 and 50282M?
Both part numbers refer to the same BlueWater Type B filter measuring 210 mm x 137 mm. The 50282M designation is simply an alternative part number used by some suppliers, such as Darlly Europe or Darlly International. If your original filter is labeled with either reference, this is the correct replacement. Both versions are sold individually.
Should I use a specific cleaner for this BlueWater filter?
BlueWater technology provides antimicrobial protection, but regular cleaning is still essential. Rinse the filter with clean water after each use and descale it periodically to extend its service life. You'll find suitable products in our spa filter cleaning products section.
How often should I replace the 50282 filter in my RIPTIDE spa?
Replacement frequency depends on how often you use your spa and your water quality. As a general rule, a spa filter should be replaced once or twice a year. BlueWater technology improves filtration performance but does not extend the life of the filter media indefinitely. Inspect the pleats regularly and replace the filter as soon as they become damaged, misshapen, or clogged.
Can I receive this filter quickly if my RIPTIDE spa is out of service?
If the 50282 filter is in stock, orders placed before 1:00 PM are shipped the same day. This filter is sold individually, so you only need to order the quantity you need without having to buy a complete set.
What should I do if the 50282 filter doesn't fit my Crystal Island spa?
Returns are accepted provided the filter remains in its original packaging, unopened and unused. Before ordering, verify that your current filter is marked with part number 50282, SC864-S, or D.03.0450, and confirm the dimensions are 210 mm x 137 mm. Doing so prevents return requests in almost every case.
