AQUALTRA Spa Filter 6CH-940 | 2 Pack for PWW50P3 and Waterways 817-0050

Overview

The AQUALTRA 6CH-940 spa filter is crafted as a reliable replacement cartridge for hot tubs that use a 6 inch outer diameter and a 7 5/8 inch length. It blends durable PET composite media with a high chlorine resistant end cap and a robust polypropylene core. All materials are BPA-free and NSF/ANSI certified, supporting a relaxing and safer leisure time in your spa. This filter is designed to balance performance with ease of use, making it a practical upgrade for regular maintenance.

Compatibility is straightforward thanks to a 1 1/2 inch SAE threaded bottom and a circular top handle for simple positioning and removal. It is listed for use with several mainstream models, including PWW50P3 (not PWW50P4), FC-0359, SD-00031, SD-01049, Waterways 817-0050, and related parts. Always confirm your hot tub or spa model matches the 6CH-940 specifications to ensure a proper fit.

Performance and filtration

The filter features an innovative Dirt-Locking design that captures more contaminants than typical fabric media. In real-life spa sessions, this translates to clearer water and a more comfortable soak, with the media helping to trap hair, leaves, dust, sediment, and sand before they circulate back into the tub. The combination of PET media with a durable core provides dependable filtration even in challenging water conditions.

Maintenance is a key part of the value. The AQUALTRA 6CH-940 is washable and reusable, making it a practical option for regular care. A simple rinse helps refresh the media, and the fabric is designed to withstand repeated use with proper cleaning routines. To avoid any adverse effects, remove the filter before cleaning and allow it to dry completely before reinstalling.

What you gain

Choosing the 6CH-940 can contribute to a smoother spa experience by supporting clearer water and consistent filtration. The 2-pack setup offers convenience and potential cost savings for routine replacements, helping you stay on top of spa maintenance without frequent shopping interruptions.
