This overall score reflects the airflow score, which is a calculation of airflow at maximum speed.

The airflow score is determined by measuring airflow speed at various points (depending on fan type) at maximum speed and calculating airflow volume.

On the lowest speed, this is the noise in dB you can expect. For context, 40dB is a whispered conversation, whereas 60dB is a normal conversation.

Many fans allow you to adjust the angle of breeze up and down.

Many fans allow you to adjust the angle of breeze up and down.

We recommend currently available fans which score 75% and above for airflow. We list other features and measurements to help you with your decision.

'Tested model' means the model should still be available for sale. In some instances, for older tests or when products are still available on the second-hand market, we include discontinued models in the tables.

This is the RRP as at time of testing.

Assume 2 hours at max. level each day, then continuous use for 8 hours on low level each night, for 3 months (92 days). Energy charged at 30c/kWh.

Pedestal fan or tower style.

How many degrees the fan oscillates from side to side.

The maximum height the fan can reach after the stand is adjusted to its highest position.

Many fans have a timer mode so they can turn off after a few hours while you sleep, for example.
