💡 Pro Tip – Rotate Two Filters for Best Results
We strongly recommend running two filters in rotation. While one filter is in your spa working hard, the other is being cleaned and dried. This means:
- Your spa never has to run on a dirty or wet filter
- Each filter lasts significantly longer
- Your water stays consistently cleaner
- You save money long-term on filter replacements
Simply order two DX50 filters and swap every 2-4 weeks. Use our 1L Filter Cleaner Soak monthly to deep-clean the resting filter and remove oils, lotions, and mineral buildup that rinsing alone can't touch.
🛠️ Installation & Maintenance Guide
Installation (5 minutes):
- Turn off spa pump and power
- Remove filter housing lid or access panel
- Lift out old DX50 filter
- Insert new compatible DX50 filter, ensuring proper seating in end cap housing
- Replace housing lid and restore power
Maintenance Schedule:
- Every 2-4 weeks: Remove filter, rinse thoroughly with garden hose, allow to dry completely before reinstalling
- Monthly: Deep clean with filter cleaner soak solution – soak overnight for best results
- Every 12-18 months: Replace filter cartridge for optimal performance
Pro Tip: Never reinstall a wet filter. Always allow to dry fully before use, or keep a second filter on hand for immediate swap.
❓ Frequently Asked Questions
Q: Will this filter fit my Happy Kiwi Spa?
A: This filter is compatible with Happy Kiwi Spas using the DX50 / Deluxe Spa 50 specification: 338mm x 124mm with 55mm end cap holes on both top and bottom. Check your current filter or owner's manual to confirm. If unsure, contact us with your spa model.
Q: How often should I replace my DX50 filter?
A: Every 12-18 months depending on usage. Signs you need a new filter: reduced water flow, persistently cloudy water despite chemical balancing, or visible wear, tears, or compressed pleats.
Q: Can I clean and reuse this filter?
A: Yes! Regular cleaning significantly extends filter life. Rinse every 2-4 weeks with a garden hose and deep-clean monthly with our Filter Cleaner Soak. Filters must still be replaced every 12-18 months as the media eventually loses effectiveness.
Q: Why should I buy two filters?
A: Running two filters in rotation is best practice. One filter stays in the spa while the other is being cleaned and dried. This maintains consistent water quality, extends the life of both filters, and means your spa never runs on a dirty or wet filter.
Q: How do I know when to clean vs replace?
A: Clean every 2-4 weeks. Replace when: filter media looks compressed or matted, pleats won't come clean after soaking, filter is over 18 months old, or you notice tears or physical damage.
Q: Do you offer free shipping?
A: Yes! This product is eligible for FREE shipping on orders over $150. Add a Filter Cleaner Soak or other spa chemicals to reach the threshold and save on delivery.
Q: Can I pick this up in-store?
A: Absolutely! We're located at 15C Douglas Alexander Parade, Rosedale, Auckland 0632. In stock and ready for immediate pickup (9am-4pm weekdays, 10am-2pm Saturdays).
