Product Specifications

Softub Compatibility

The ProAqua PA-1610 is identified as a replacement filter for compatible Softub models manufactured before September 2009.

Not all older Softub models use the same filter connection. Confirm the cartridge dimensions and attachment style before purchasing.

Before ordering, check:

• Your Softub's approximate manufacturing date.

• The filter connection and mounting style.

• The dimensions of your existing cartridge.

• Any part number printed on the original filter.

• Whether your spa has been modified or upgraded to a different filtration system.

If you're unsure whether this filter fits your spa, contact Splash Pool & Spa with your Softub model, approximate year, and a photo of the existing filter.

Why Replace Your Softub Filter?

A clean, properly functioning spa filter helps maintain water clarity and supports effective water circulation.

Over time, filter media can accumulate dirt, oils, and other contaminants. Even with regular cleaning, cartridges eventually need replacement.

Signs you may need a new filter include:

• Persistent debris or cloudy water despite proper water chemistry.

• Filter media that remains dirty after cleaning.

• Torn, damaged, or deteriorated pleats.

• Reduced filtration performance caused by a clogged cartridge.

• A cartridge that has become misshapen or damaged.

Water clarity also depends on proper sanitizer levels, water balance, and routine spa maintenance.

Filter Care & Maintenance

1. Follow your Softub manufacturer's recommended cleaning schedule.

2. Remove the cartridge according to your spa's instructions.

3. Rinse away loose debris using an appropriate water spray.

4. Use a spa filter cleaner when recommended.

5. Rinse thoroughly before reinstalling.

6. Replace the cartridge when it is damaged or no longer cleans effectively.

Always follow the manufacturer's instructions for safe filter removal and installation.
