📏 Bellagio Customers: Measure Before Ordering

Bellagio has produced different filtration configurations, and replacement filters should never be selected by brand name alone. Please remove and measure your existing cartridge before placing your order.

1. Confirm that the filter body is approximately 6 inches in diameter.
2. Confirm that the overall length is approximately 8¼ inches.
3. Confirm that the top has the same semi-circular handle.
4. Confirm that the bottom uses a 1½-inch SAE threaded connection.
5. Confirm whether your spa requires one or two filters.

All measurements and end-cap features must match. If you are uncertain, contact Southern Leisure with pictures of your current filter’s top, bottom and overall measurements before ordering.

📋 How to Replace

1. Turn off power to the hot tub at the breaker.
2. Remove the filter cover or skimmer assembly.
3. Unscrew the existing filter cartridge from the housing.
4. Remove all protective packaging from the new filter.
5. Thread the replacement filter gently into the housing by hand.
6. Do not overtighten the cartridge.
7. Reinstall the filter cover or skimmer assembly.
8. Restore power and confirm normal water circulation.

💬 Southern Leisure Says

When selecting a replacement filter, physical measurements and connection style are more dependable than the square-foot rating shown in a spa brochure. Always compare the diameter, length, handle and threaded bottom with your existing cartridge.

Bellagio owners should measure before ordering. If you need help, send Southern Leisure pictures of the filter’s top and bottom along with its overall measurements.
