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. The CHOICE Expert Rating is the airflow score.

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 pedestal fans which score at least 80% and above for airflow and tower fans which score at least 75% and above for airflow.

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.

Light ones are easier to move, heavy ones may have a stable base.

Measured at widest point, rounded to closest cm.

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

Handy so you don't have to physically get up to change settings. Make sure any button battery compartments are secured with a screw or require two deliberate actions to open, to prevent children from accessing them.

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