The K30 oral irrigator is designed specifically for children aged 3 to 14. It is the industry's first to utilize top-level sensing technology. It automatically stops the water jet when it senses that it is at a certain distance from the lower jaw, ensuring that the water column does not pose a threat to the child's safety. It has a long-lasting battery life and can be used for up to a year on a single charge. During charging, it also has an automatic sterilization function, with an effectiveness of up to 99.99 percent.
