Nine adjustable suction levels from gentle to strong, up to 65 kPa, allowing precise adaptation to different nasal congestion situations. Use the low setting to gently clear thin mucus; the suction power quickly removes thick secretions, reducing repeated irritation to the nasal cavity. Foodsafe materials and backflow protection: the suction tip is made of foodsafe silicone to be soft and gentle on the nasal mucosa. The innovative backflow protection provides a oneway flow into the container, eliminating the risks of backflow, leakage or aspiration and protecting the baby's respiratory tract. Two deep and flat nose suction attachments: includes two removable silicone attachments. The small nozzle is designed for deep nasal passages to precisely remove hidden mucus; the large nozzle handles tougher secretions and enlarges the contact area to improve cleaning efficiency. Both attachments are removable and can be rinsed with boiling water or sterilised in a steriliser to remove bacteria residue. Quiet operation and easy to use: lowfrequency technology keeps noise near a whisper, so the baby is not woken during sleep. Two buttons on the unit: the button powers the device, the bottom button adjusts suction levels, providing straightforward operation for both and experienced parents. Use scenarios Newborns with nasal congestion: attach the small nozzle, select a gentle suction level, and carefully clear nasal passages to improve breathing without disturbing the baby. Infants and toddlers with thick secretions: switch to the large nozzle and higher suction level to remove tougher mucus efficiently, then clean the attachments after use. Nighttime relief: the nearsilent operation helps maintain a calm sleep routine; use on a low to mid setting with the appropriate nozzle to keep the baby's nasal passages clear without waking them.
