There are some key differences between AirFloss Pro or AirFloss Ultra and previous models of AirFloss. If your AirFloss has three LED lights, and it also has a decorative accent ring on the handle where the nozzle attaches, you have the latest version: the AirFloss Pro or AirFloss Ultra. Earlier AirFloss models do not have these features. The AirFloss Pro and AirFloss Ultra are also different from previous AirFloss models in terms of the results they provide. The AirFloss Pro and AirFloss Ultra are the highest performing AirFloss models, with gum health results as good as string floss, and removes 99.9% plaque from treated areas. If you are not sure which model of AirFloss you have, you can look at the bottom of your handle to identify the model. AirFloss Pro and AirFloss Ultra are identified by an "HX" number beginning with 83 (for example: HX8340). If you still cannot identify the model of AirFloss you have, you can also contact Philips Support by phone or visit the Philips Support website to get in touch with a Philips representative.
