Frequently Asked Questions
-
Replace your filter every 12-24 months depending on usage frequency, bather load, and maintenance routine. Heavy use may require more frequent replacement. Signs it's time to replace include decreased water flow, difficulty cleaning, visible wear or damage, and persistent water clarity issues despite proper chemical balance.
-
This filter (part #10-05338) is designed specifically for Bullfrog Calm™ Series models manufactured in 2026 and later. Bullfrog redesigned their filtration system for 2026+ models, so this filter will NOT fit pre-2026 Calm™ Series spas. Check your owner's manual or current filter for the part number to confirm compatibility.
-
Genuine Bullfrog filters are manufactured to exact OEM specifications, ensuring proper fit, optimal flow rate, and maximum filtration efficiency. Aftermarket filters may use inferior materials that degrade faster, provide inadequate filtration, or restrict water flow, potentially damaging your spa's pump and heater. Genuine filters protect your warranty and your investment.
-
Rinse your filter weekly with a garden hose to remove surface debris. Monthly, perform a deep clean by soaking the filter overnight in a filter cleaning solution, then rinse thoroughly. Every 3-4 months, use a filter degreaser to remove oils and lotions. Never use household cleaners, bleach, or pressure washers, as these can damage the filter media.
-
This filter is engineered specifically for the Calm™ Series (2026+). While Bullfrog uses similar filtration technology across their product line, each series has unique specifications. Using the wrong filter can result in poor performance, equipment damage, or voided warranties. Always verify part numbers before ordering.
