The airwatt is a valuable measurement of vacuum cleaner motor efficiency because it represents the power carried by the fluid flow (in the case of a typical household vacuum, this fluid is air). The power of the airflow is equal to the product of pressure and volumetric flow rate. Unlike electrical power (measured in watts), which includes ...

Air ionisers are used in air purifiers to remove particles from air. [3] Airborne particles become charged as they attract charged ions from the ioniser by electrostatic attraction . The particles in turn are then attracted to any nearby earthed (grounded) conductors, either deliberate plates within an air cleaner, or simply the nearest walls ...
