Philips Sonicare HX3911/40

Quad Stream Technology

The specially designed Quad Stream nozzle ensures twice as effective cleaning as an interdental brush. The Quad Stream nozzle concentrates the water into an X-shape, creating four streams that completely treat the entire oral cavity in just a few moments. By cleaning the interdental spaces, it helps eliminate bad breath and leads to improved gum health. The nozzle head is made of soft rubber and is very gentle on the gums. It can be easily attached and detached from the body of the device.

Effective and easy cleaning

Give your oral cavity the best possible care. The Philips Power Flosser removes 99.9% of plaque and debris from between the teeth, the sides of the teeth, and the gum line. The Quad Stream nozzle concentrates the water jet into four wide streams. This increases the treated area, leading to more effective removal of interdental plaque.

4 modes and 10 intensities

Remove debris from between your teeth in the way that is most comfortable for you. The Philips Sonicare Power Flosser HX3911/40 offers a Clean mode for effective cleaning with a continuous stream of water, a Deep Clean mode where the water stream pulses for an extra thorough clean, a Sensitive mode for the care of sensitive teeth, and a Massage mode to soothe and stimulate the gums. You can easily select the treatment intensity manually, with 10 levels available. At the highest intensity level of 10, the maximum pressure of the device is 13 bars.

Pulse Wave technology

The Philips Sonicare Power Flosser HX3911/40 is designed to make cleaning easier and guide you towards the optimal cleaning method. Thanks to the advanced Pulse Wave technology, the device takes short breaks between individual water pulsations, prompting you that it's time to move from treating one interdental space to the next. This ensures you've given the same amount of time to all areas of your oral cavity.

Quiet operation

Using the Philips Sonicare Power Flosser is very discreet. Even in the most intensive mode, the device's operation is almost silent.

4 nozzles

Take care of your oral health exactly as you need to. The package includes 4 nozzles that can be interchanged as you wish: 2 single-stream nozzles and 2 Quad Stream nozzles that direct the water flow into an X-shape. The device also comes with a compact case for hygienic storage of the nozzles at home or on the go.

Magnetic docking station

After cleaning your oral cavity, simply place the body of the oral irrigator onto the designated spot on the magnetic docking station. You don't need to do anything else; the device is equipped with an auto-shutoff feature.

600ml reservoir

The Philips Sonicare Power Flosser comes with a 600ml reservoir, which is a sufficient amount for a complete treatment of the entire oral cavity. To refill, simply flip open the reservoir lid.
