Top 3 Box Fans Under $40 Reviewed
#1 PELONIS 2295 CFM Box Fan: Best Overall
Why We Picked It
The upgraded PELONIS 20 inch box fan moves up to 2,295 CFM with five blades and a copper motor while using only 55W.
PELONIS rates this box fan at up to 2,295 CFM with an air throw of 25ft/s, strong numbers for a fan that draws only 55W. Three speeds run from a gentle breeze to a strong gust, and the five 20 inch blades spread air evenly across a room. PELONIS designed it to work in three places: in a window to pull in fresh air, on a desk or counter for personal cooling, or on the floor to circulate air through a room. A built-in handle makes it easy to move between those spots, and the copper motor is backed by a 1-year warranty.
Key Specifications
- Size: 20 inch
- Airflow: 2,295 CFM
- Air Throw: 25ft/s
- Power: 55W
- Blades: 5
- Speeds: 3
- Warranty: 1 year
| Pros | Cons |
|---|---|
|

Things to Consider
Its low power draw makes it cheap to run all night, and you can pair it with an air conditioner to spread cool air further.
Best For
This box fan is best for bedrooms, living rooms and home offices.

#2 Amazon Basics 3-Speed Box Fan: Best Lightweight
Why We Picked It
Amazon Basics’ 20 inch box fan uses 67 watts, weighs 5.8 pounds and stands on extra-large feet that keep it from tipping or wobbling.
This is a simple, inexpensive 20 inch box fan that does the basics well. Three speed settings, low, medium and high, let you match the breeze to your comfort level, and five blades provide steady airflow. At 5.8 pounds with a carry handle on top, it is one of the lighter full-size box fans, so it moves easily between a bedroom, living room, kitchen or home office. Amazon Basics fits it with extra-large feet so it stands free without tipping or wobbling, a common complaint with cheap box fans. It draws 67 watts and measures 6.8 x 20.86 x 21.33 inches.
Key Specifications
- Size: 20 inch
- Speeds: 3
- Blades: 5
- Power: 67 watts
- Weight: 5.8 pounds
- Dimensions: 6.8 x 20.86 x 21.33 inches
- Feet: Extra-large
| Pros | Cons |
|---|---|
|
|
Things to Consider
It is a good spare fan for a guest room or a first apartment, where a plain, stable fan at a low price is all you need. Its light weight also makes it easy to lift into a window, though Amazon Basics markets it as a floor fan.
Best For
This box fan is best for bedrooms, guest rooms and first apartments.

#3 Xcity 18 Inch Metal Box Fan: Best Metal Fan
Why We Picked It
Xcity’s 18 inch metal floor and box fan moves up to 4000 CFM, tilts through 360 degrees and is built with a full-metal frame and aluminum blades.
The Xcity is a compact shop-style box fan at a home-fan price. Its listing rates airflow up to 4000 CFM across three speeds, enough to ventilate a garage or warehouse corner. A thickened copper-wound motor runs on dual ball bearings for smooth, quiet operation, and Xcity says it boosts energy efficiency by 35%. The heavy-duty metal body and corrosion-resistant aluminum blades hold up to daily use, and the head tilts through 360 degrees to send air exactly where it is needed. It is UL listed, has a reinforced grille and a non-slip base, and weighs 7.26 pounds.
Key Specifications
- Size: 18 inch
- Airflow: Up to 4000 CFM
- Speeds: 3
- Tilt: 360 degrees
- Motor: Copper-wound, dual ball bearings
- Weight: 7.26 pounds
- Safety: UL listed
| Pros | Cons |
|---|---|
|
|
Things to Consider
Its 18 inch size is a little smaller than a standard box fan, so it fits on a workbench or shelf while still moving a lot of air. The dual ball bearings should keep it running smoothly through long summer days in a garage.
Best For
This box fan is best for garages, workshops and home gyms.

What to Expect from Box Fans Under $40
A box fan is a square fan in a frame that pushes a broad column of air straight ahead. It does not cool the air, but moving air over your skin makes a room feel several degrees cooler, and standing one in a window or doorway can pull fresh air in or push hot air out of a room. Box fans are cheap to buy, cheap to run and easy to store.

How to Choose Box Fans Under $40
Compare Airflow
Airflow is listed in cubic feet per minute, or CFM. Standard 20 inch box fans list figures in the low thousands, while high velocity and metal shop fans list much more. Not every brand publishes a CFM figure, so compare speeds, blade design and motor power too.
Plastic or Metal
Plastic box fans are light, cheap and easy to carry. Metal box fans with steel housings and aluminum blades are heavier and cost more, but they handle garages, workshops and daily heavy use better and often tilt to aim the air.
Check the Noise
Box fans hum more than tower or pedestal fans, especially on high. If you will sleep with one on, look for a listing that describes quiet operation, run it on low and choose a fan with more speeds or a variable control so you can find a quiet setting.
Think About Controls
Most box fans use a simple three-speed dial on top. A few add front controls, a digital display, a timer or a thermostat that switches the fan on and off or adjusts its speed with the room temperature, which is useful overnight.
How We Evaluate Box Fans Under $40
We rank box fans on manufacturer specifications and listing details: size, rated airflow, speeds, controls, noise, build and price. We kept only new, in-stock box fans and left out multi-packs, color duplicates, resold third-party copies and accessories such as filter clips and replacement feet. For this list we kept only new, in-stock fans listed under the price cap, then weighed airflow, build and noise.
Frequently Asked Questions
What CFM should a box fan have?
A standard 20 inch home box fan is fine for a bedroom or living room. For a garage or workshop, a high velocity or metal box fan with a much higher CFM rating moves air further.
Which box fan is the quietest?
Look for fans described as quiet or whisper quiet, more speeds or variable control, and run them on low. Small personal box fans are usually quieter than full-size ones.
Is it safe to leave a box fan on all night?
Yes, for a fan in good condition with an undamaged cord. A timer or thermostat lets it switch off or slow down on its own.
How much does a box fan cost to run?
Very little. Most box fans use well under 100 watts, a small fraction of what an air conditioner draws.
Final Verdict
The PELONIS 2295 CFM Box Fan is the best box fan under $40, with strong rated airflow on just 55W. For a light, stable fan, choose the Amazon Basics 3-Speed Box Fan, and for a metal fan that tilts, the Xcity 18 Inch Metal Box Fan.
