For users requiring urgent oxygen, backup devices are recommended, as this product is not for life support.

Maintenance

Regular maintenance is essential for optimal performance. This includes cleaning the exterior shell, cleaning or replacing the disposable oxygen inhaler, and replacing the air intake filter pad every six months (or quarterly in dusty environments). Battery maintenance involves charging the battery every three months if the device is not in use for extended periods.
