FAQs
1. How do I know this fits my Freeflow Spa?
Check your spa model against the compatibility list. If your spa uses the Freeflow 46 style filter or one of the listed codes, this cartridge will fit.
2. How often should I replace the filter?
Most spa owners replace filters every 6 to 12 months, depending on use. If the water becomes harder to balance or the flow drops, it may be time to change it.
3. Do I need any tools to install it?
No. This filter is designed as a simple drop-in replacement. Just remove the old one and put the new one in place.
4. Can I clean and reuse this filter?
Yes. Rinsing the pleats with fresh water helps extend its lifespan. Avoid using harsh cleaners that can damage the media.
5. Is this better than the original OEM filter?
It performs the same role and is made in NZ to handle regular spa use. Many customers choose it as a reliable, cost-effective alternative.
