The Ultra Performance grill design provides up to 20% more airflow with three energy-efficient speeds. This model also features the Weather-Shield motor for safe window use in inclement weather. They’re economical, technologically innovative and portable — they even come equipped with a carry handle, so you can take them wherever you need them. All Lasko box fans are made in America and are guaranteed to be both long-lasting and energy-efficient.
To track energy consumption, we plugged each fan into a P3 International Kill A Watt EZ electricity usage monitor while running them for two hours at their highest speed, without oscillation. We set up all the fans, one at a time, in the same spot and plugged into the same outlet in our Lasko Box Fan approximately 1,250-square-foot finished basement. We tracked the falling temperature of the room during our tests using the SensorPush HTP.xw Wireless Thermometer/Hygrometer with its iOS app on an iPhone 11; the SensorPush device was calibrated using a Boveda One-Step Calibration Kit.
Office floor and box fans move air at floor or surface level for spot cooling near desks or workstations and for general cooling in open areas. These lightweight cooling fans can be freely moved between locations. They have a motor that rotates the fan blades to move air and a guard that helps protect the blades from damage and prevent injuries from accidental contact. They’re used as a cooling fan in clean, dry environments such as offices, residences, healthcare facilities, and light commercial and manufacturing spaces. The Lasko 20-inch 3-Speed Box Fan combines the cooling power of 3 fan speeds with the wide-area air flow of 2500 CFM air circulation and a 20-inch fan diameter, all in a compact, lightweight, energy-efficient design. The 6 feet cord and slip-resistant feet allow flexible placement without fan slippage and the built-in carry handle makes it easy to transport the fan between rooms.
When deciding which alen breathesmart to buy, know that the different models have more in common than they have differences. They all feature the patented Blue Plug safety fuse technology, a mechanism that cuts power to the fan if an electrical fault in the motor or power supply is detected. They’re all Electrical Testing Laboratories listed, which means they comply with OSHA’s North American safety standards. They come either completely assembled or require simple, no-tools assembly and they’re all manually controlled. Yes, it’s round, but the Lasko Cyclone is as effective a box fan as they come.
It all comes down to personal preferences and the nature of your space. The following three considerations will help you make the best choice for your unique needs. Over time, the wire that runs up the back of the fan behind the blades may come into contact with the blades, and become damaged or severed.
