Product Specifications

Compatibility - Important Before Ordering

This cartridge is intended for compatible Softub models manufactured before 2009.

Softub filter designs have changed over time, so the year of manufacture alone may not guarantee a correct fit.

Before ordering, compare your existing filter's:

• Overall length and outside diameter.

• Opening and connection style.

• Original part number, if available.

• Softub model and approximate production year.

This is an older-style replacement filter and should not be assumed compatible with newer snap-on Softub filter systems.

If you're unsure which cartridge you need, contact Splash Pool & Spa with a photo of your existing filter and your Softub model.

How to Clean Your Softub Filter

Regular filter cleaning helps maintain proper water circulation and spa performance.

1. Disconnect your Softub from electrical power before removing the cartridge.

2. Remove the filter according to your spa's operating instructions.

3. Rinse between the filter pleats using clean water.

4. Use a spa filter cleaning product when recommended, following its label directions.

5. Rinse thoroughly before reinstalling.

6. Replace the cartridge if the filter media is damaged, excessively worn, or no longer cleans effectively.

Avoid harsh cleaning methods that could damage the filter media.

When Should You Replace Your Spa Filter?

Consider replacing your cartridge if you notice:

• Damaged or deteriorating filter pleats.

• Persistent debris that cannot be rinsed away.

• Reduced circulation after cleaning.

• A damaged filter connection or end cap.

• A cartridge that no longer maintains acceptable filtration performance.

Regular water testing, appropriate sanitizer levels, and routine filter care all contribute to a cleaner spa.
