Buying Guide
Which One Should You Choose?
Identical core specs, same multi-dimensional technology. The difference is in the design and the airflow.
- Prefer curved lines and the feel of four-sided whole-room airflow — choose the T5 Sleep Device
- Prefer a book-shaped form, no direct airflow from the top, and a desktop-friendly look — choose the Z5 Sleep Device
- Want a higher negative oxygen ion concentration — the Z5 measures slightly higher at 3 m (58,230 vs 47,330)
- For nurseries and kids' rooms, we recommend the Z5 (wide-angle side airflow with no direct draft)
Both are sleep devices made for the nightstand, with multi-dimensional technology working at the same time. Choose the look, choose the habit — the core is the same.
Same core, different look.
