Frequently Asked Questions
Q: Will this fit my Happy Kiwi Spa?
A: This filter suits Happy Kiwi Spas using the DX50 / Deluxe Spa 50 specification. Confirm your current filter measures 338mm x 124mm with 55mm end cap holes on both ends. If unsure, contact us with your spa model.
Q: How often should I replace the filter?
A: Every 12-18 months depending on usage. Replace sooner if you notice reduced water flow, persistent cloudiness, or visible wear to the pleats.
Q: Can I clean and reuse this filter?
A: Yes, regular cleaning extends filter life. Rinse every 2-4 weeks and deep clean monthly. Cartridges still need replacing every 12-18 months as the media gradually loses effectiveness.
Q: Why should I run two filters in rotation?
A: Running two filters means your spa always runs on a clean, dry cartridge while the other is being cleaned and dried. This maintains consistent water quality and extends the life of both filters.
Q: Do you stock other Happy Kiwi Spa filters?
A: Yes, we stock a range of spa filter cartridges. Contact us with your filter dimensions if you cannot find your model.
