The 8 Best Box Fans
Updated by · How we research
Box fans and two pivoting drum fans compared on noise, power use, cleaning and safety, with the five-speed Vornado Model 80 as the best overall pick. When users buy our independently chosen editorial choices, we may earn commissions to help fund the Wiki.
Most box fans print an airflow number, but no common test stands behind those figures, so a fan claiming twice the air of another rarely moves twice as much. What does hold up: the strongest fans are the loudest, power draw varies a lot, and an old fan can be a fire risk. This guide is for cooling a bedroom, window or garage.
Editor's Notes
October 23, 2026, by Ezvid Wiki Admin:
First place goes to a newcomer, the Vornado Model 80. Five speeds, a grille that comes off for cleaning and a five-year replacement promise are rare on a square fan, and Vornado publishes its power draw for each setting. The Hurricane Classic stays as the best value, and new picks cover bedrooms, garages, aiming air and a timer model.
Nine of the ten earlier picks are out. The Vornado 270, Lasko 2264QM, Lasko 3720 and Holmes Comfort Control have no live listings, the OPolar and Black+Decker Mini are small desk fans, the Patton is an expensive drum fan, and the earlier Pelonis is unavailable, so its current 20-inch model replaces it. The Air King 9723 did best for airflow in Bob Vila's box-fan test, but it had no price or stock when we checked, so it's off for now.
The most useful evidence was Bob Vila's measured test of nine box fans, with wind speed, decibel and wattage readings, plus the CPSC's two Lasko recalls, which matter to anyone still running a fan from the early 2000s.
January 21, 2021:
While the Holmes Personal and Bionaire Twin fell by the wayside due to availability issues, we quickly found two new replacements for them, namely the Pelonis PFB50A2ABB-V — a budget-friendly model with a 20-inch propeller; and the Black+Decker Mini — a slight option with a nine-inch propeller that’s suitable for use on a basement window sill, or as a desktop unit.
We also observed that our top-ranked Vornado 270 Panel appeared to be suffering from some widespread availability issues, but after reaching out to a representative from the company, we were quickly assured that the 270 should be back in stock within a month of this update’s publication.

February 15, 2019:
Box fans come in many shapes and sizes and have multiple applications, and although they don't have to technically be a square, they do need to have a grille or latticework enclosure. We added larger models like the Air King 9723, Lasko 3720, and Hurricane Classic for users who needed to ventilate or exhaust entire rooms, along with dedicated window, floor, and personal units. Placed the Vornado 270 Panel at the top spot due to its ingenious technology, attractive design (something that seems to go overlooked in the category) and durability. Because quality control tends to be hit or miss with myriad products across the field, we favored selections with warranties.
Special Honors
Lasko Classic Box Fans Lasko's plain 20-inch box fans, such as the three-speed 3733 with a fused safety plug, are the ones most hardware and home stores stock, and they were not available to price for this list. The 2011 recall covered units made in 2002 to 2004, not new ones, but check the date stamp on any older Lasko you still use. lasko.com
Airflow Claims, Noise And Power Draw
A fan with more speeds gives you more choices between quiet and breezy, and a removable grille lets you wipe the blades, since a dusty fan is a noisier and weaker one.
Almost every box fan prints an airflow number in cubic feet per minute, but there's no common test behind those figures, so a fan claiming twice the air of another rarely moves twice as much. Measured numbers tell a calmer story. In Bob Vila's test of nine box fans, the 20-inch models all blew about 11.6 to 12.6 mph on high, while a 9-inch tabletop box fan managed 5.8 mph.
Power is where fans differ more. The same test metered 20-inch fans from about 43 to 84 watts, and the strongest fan, the Air King, was also the loudest at 74 to 77 decibels from 2 feet. Vornado lists its Model 80 at 120, 90 and 70 watts across its settings, and the Model 80X at up to 85 watts with a DC motor that uses very little on its lowest steps.
For sleep, judge a fan by its low setting, not its high one. A fan with more speeds gives you more choices between quiet and breezy, and a removable grille lets you wipe the blades, since a dusty fan is a noisier and weaker one.
Box Fan, Drum Fan Or Tower Fan
The 20-inch square box fan is the standard size, and it's the only common size that fits a 20-by-20-inch furnace filter for a homemade air cleaner. Smaller 9- to 12-inch box fans are desk fans: quieter, but they move far less air. Round drum or "wind machine" fans pivot or tilt to throw air farther and suit garages and drying jobs, but they won't sit flat in a window.
A tower fan is the usual alternative indoors. Towers are quieter, slimmer and better looking, and many oscillate, but they move less air for the money. A Bob Vila floor-fan roundup of 13 fans covers towers, pedestals and circulators if you want those trade-offs side by side.
In a window, a box fan works best as an exhaust at night: face it outward to push hot indoor air out and let cooler air come in through other open windows. Turn the feet sideways or remove them so the frame sits on the sill. Most box fans aren't made to get wet, so close the window and unplug the fan before rain.
Old Fans, Windows And DIY Air Filters
Old box fans deserve a look before summer. In 2006 the U.S. Consumer Product Safety Commission announced a Lasko recall of 5.6 million box and pivoting fans made from 1999 to 2001, sold under the Lasko, GE, Galaxy and Air King names, after reports of motor fires. In 2011 came a second recall of 4.8 million Lasko box fans, models 3720, 3723, 3733 and Galaxy 4733 with a 2002-03 or 2003-04 date stamp on the bottom of the frame. A CPSC study of portable fan incidents found that fires made up most of them, with box fans among the most common types.
The habits that matter: replace a fan with a damaged cord or a motor that smells hot, look for a UL or ETL mark, plug it straight into the wall rather than an extension cord, and don't leave it running for days in an empty house. Keep the back clear so the motor can breathe.
A box fan with four MERV 13 furnace filters taped around it makes a Corsi-Rosenthal box, a cheap air cleaner used during wildfire smoke. A University of Connecticut fire department evaluation found no added fire concern over a normal fan, but build it with a recent, safety-listed fan, not an old one.
How we researched this
We compared 17 fans across box, drum and tabletop styles, read Vornado's published specs and the makers' stated specs for the rest, used Bob Vila's measured test of nine box fans for airflow, noise and power figures, looked for patterns in owner feedback, and checked every brand against U.S. Consumer Product Safety Commission recalls.

Frequently asked questions
Does a box fan cool a room?
No. A fan moves air but doesn't lower its temperature. It feels cooler because moving air speeds up evaporation from your skin. In a window at night, it can pull in cooler outdoor air.
Is a box fan or a tower fan better?
A box fan moves more air for the money and fits a window. A tower fan is quieter, slimmer and often oscillates, so it suits living rooms and bedrooms where looks and noise matter more.
Is it safe to run a box fan all night?
A recent fan with a UL or ETL mark, an undamaged cord and a clear back is fine for overnight use. Replace old fans, check older Lasko fans against the 2006 and 2011 recalls, and avoid extension cords.
Should a window box fan face in or out?
Face it out at night to exhaust hot indoor air while other windows let cooler air in. Face it in when the outdoor air is cooler and you want a direct breeze. Unplug it before rain.
How much airflow do I need?
Airflow ratings have no common test standard, so compare them loosely. Any 20-inch box fan stirs a bedroom; a pivoting drum fan helps in garages, large rooms and drying jobs.
Can I make an air filter with a box fan?
Yes. A Corsi-Rosenthal box uses a 20-inch box fan and four MERV 13 furnace filters. Use a recent, safety-listed fan and don't leave it running unattended for long periods.
