Why Replace Your Hot Tub Filter?
Regular filter replacement helps:
- Improve water clarity
- Increase filtration efficiency
- Reduce strain on pumps and heaters
- Improve sanitizer effectiveness
- Extend spa equipment life
- Maintain proper water circulation
For best results, rinse your filter every 2 to 4 weeks and perform a deep cleaning every 3 to 4 months. Replace the cartridge every 12 months, or sooner in heavily used spas.
Pro Tip
Keeping a second filter cartridge on hand allows you to rotate filters during cleaning cycles. This helps maintain maximum filtration performance and can significantly extend the life of both cartridges.
