Buying Guide: Key Purchase Considerations

- Control and connectivity: Apps and remote control simplify scheduling and maintenance, but verify compatibility with your WiFi and phone.
- Filtration and water quality: Integrated filters and ozone help maintain clarity and reduce maintenance; ozone is optional but beneficial in busy setups.
- Installation and accessories: Check included hoses, pumps, and mounting accessories. Some systems require additional pumps or adapters for DIY tubs.
- Maintenance windows and safety: Consider auto-shutoff features and timers to protect against overcooling or long idle runs.
- Noise and footprint: If placed in living spaces, select models with quiet operation and a compact footprint.
