💬 Southern Leisure Says

Bullfrog’s six-month replacement recommendation is shorter than the schedule used for many traditional pleated spa filters. Follow the Calm filter’s actual package instructions: rinse it monthly and replace it every six months rather than waiting for obvious damage or restricted water flow.

Keeping a second filter on hand makes monthly maintenance easier. One filter can be cleaned and allowed to dry completely while the other remains installed in the spa.

🧼 Care & Maintenance

• Remove and rinse the filter monthly.
• Use a garden hose with moderate water pressure.
• Rinse carefully between each pleat from top to bottom.
• Rotate the filter while rinsing to clean the entire cartridge.
• Periodically use a dedicated spa-filter cleaning solution to remove oils and residue.
• Rinse away all filter-cleaning solution before reinstalling the cartridge.
• Do not use a pressure washer, stiff brush or sharp cleaning tool.
• Do not clean the filter with bleach or household detergent.
• Replace the filter every six months according to Bullfrog’s package instructions.
• Replace it sooner if the pleats become torn, collapsed, damaged or permanently restricted.
