Halo Tower

The EcoAir Halo is a slim DC tower fan that's as easy on the eye as it is on your electricity bill. Drawing just 2.8 watts of power, it's one of the most economical tower fans you can run — at ~26p/kWh that's a tiny fraction of a penny per hour, near-negligible even left on all day. Its tall, narrow profile slots neatly into tight corners and beside furniture where a bulky pedestal fan won't fit, making it ideal for bedrooms, home offices and living rooms alike. A standout for night-time use is the dimmable, low-light digital display, so there's no bright glow keeping you awake. Twelve speed settings let you fine-tune the airflow precisely, oscillation sweeps cool air across the room, and a remote control puts everything within reach from bed or sofa. An auto shut-off feature adds convenience for overnight running, and because it circulates air so efficiently it's useful year-round — cooling in summer, moving warm air in winter. Finished in black and weighing 10kg, the Halo is priced at £129.99. For buyers who want a stylish, space-saving and exceptionally low-power tower fan that won't light up the bedroom, it's a compelling pick.
