1. Can I use regular tap water for nasal irrigation?
No, it is strictly recommended to use only distilled, filtered, or previously boiled (and cooled) water. Never use plain, untreated tap water to prevent sinus irritation or infection.
2. How often should I replace the brush heads?
For optimal hygiene and cleaning effectiveness, we recommend replacing the toothbrush head every 3 months or sooner if the bristles appear frayed.
3. Is the device safe for travel?
Yes! Both devices are cordless and USB rechargeable, making them perfect for maintaining your hygiene routine while on the go.
