The Philips Sonicare HX3042/00 is a set of two replacement standard nozzles designed specifically for use with Power Flosser electric interdental cleaners. These white plastic attachments feature a clear tip and a single jet that effectively removes food debris from between teeth and along the gumline. To help you reach the back of your mouth and other difficult areas, the nozzle is designed with a 360-degree rotation. You can easily attach them to your device using a simple snap-on system, and for the best hygiene and performance, it is recommended to replace them every six months.
