Comparison PECHAM Professional vs B.Well WI-922

The number of pulsations per minute indicates the rhythm of the water jet's impact on teeth and gums. Frequent impulses sequentially loosen and wash away impurities, and the flow feels more continuous and gentle. However, for example, 1800 pulsations per minute are not necessarily more effective than 1200, as the result also depends on the water jet's strength, the nozzle, and the irrigator's design.

The irrigator pressure determines the force of the water jet and directly affects cleaning intensity. Values around 20–40 PSI are suitable for getting used to the device and gentle care, while 70–100 PSI provides more powerful rinsing of hard-to-reach areas. A wide range allows you to select a comfortable flow strength for gums, implants, braces, and different nozzles.

Timing helps maintain the recommended irrigator usage time and treat all areas of the oral cavity consistently. The timer can emit short signals at regular intervals or stop the water flow after the program is complete. It is especially useful for beginner users and children who find it difficult to control the duration of the procedure on their own.

Cable length affects the convenience of connecting a stationary irrigator to the power outlet and the choice of installation location. A longer cord allows the device to be placed further from the power source, while a shorter one may require the use of an extension cord.

A case or cover is designed for storing and transporting a portable irrigator together with attachments and a charging cable. It protects the device from dust, scratches, and accidental damage in luggage, and helps keep the set in one place. A hard case withstands impacts better, while a soft cover is lighter and takes up less space.
