Why We Picked It
BLACK+DECKER’s BFB20SW is a 20 inch box fan with an 80W copper motor rated at over 1200CFM, three speeds and a 6 ft. cord.
This BLACK+DECKER box fan is a straightforward 20 inch fan from a brand most people know. Its copper motor delivers up to 80W of power for over 1200CFM of airflow, and three speeds are set from a mechanical rotary dial. At 20.67 x 4.13 x 21.06 inches and 7.05 lbs it is slim enough to sit in a doorway or window frame and light enough to carry to the garage. Stabilizing plastic feet keep it steady on the floor, the carry handle is built in, and a 6 ft. cord gives you more reach than many budget fans. BLACK+DECKER suggests it for bedrooms, offices, garages and basements.
Key Specifications

- Airflow: Over 1200CFM
- Power: 80W copper motor
- Speeds: 3
- Cord: 6 ft.
- Weight: 7.05 lbs

#2 Hurricane Classic Box Fan: Best for Airflow
Why We Picked It
Hurricane’s Classic is a 20 inch floor box fan rated at 2400 CFM and 1100 RPM, with three quiet speeds and a slim frame that stores easily.
Hurricane is a hydroponics brand, and its Classic box fan is built to keep air moving in grow rooms, gyms and workshops as well as bedrooms. The listing rates airflow at 2400 CFM at 1100 RPM, which is more than most standard 20 inch box fans claim. Three speed settings cover a gentle breeze through a strong draft, and Hurricane describes them as quiet. Lightweight polymer blades and a slim frame with adjustable feet keep it at 7 pounds and easy to slide into a closet at the end of summer. It is a plain, honest fan that moves a lot of air for the money.
Key Specifications
- Size: 20 inch
- Airflow: 2400 CFM
- Motor Speed: 1100 RPM
- Speeds: 3
- Blades: Polymer
- Weight: 7 pounds
- Dimensions: 20 x 20 x 3.5 inches

Things to Consider
Its ventilation focus makes it a good pick for clearing stale air or fumes from a garage or basement, not just cooling a bedroom. The white version is usually the cheaper of the two colors.
Best For
This box fan is best for bedrooms, basements and workshops.

#3 shinic 20 Inch Box Fan with Thermostat: Best with Thermostat
Why We Picked It
shinic’s 20 inch bedroom box fan has an adjustable thermostat that regulates fan speed on its own, three quiet speeds and a sturdy metal frame.
Most box fans run at whatever speed you set until you turn them off. This shinic adds an adjustable thermostat that keeps the room near your chosen temperature by regulating the fan speed automatically, so the fan works harder in the heat of the evening and backs off as the room cools overnight. Three energy-efficient speeds are designed for quiet performance with minimal vibration. Aerodynamic blades and a high-performance motor give strong, far-reaching airflow, and the white metal frame feels sturdier than plastic. It can sit in a window, on a table or on the floor, and a carry handle makes it easy to move.
Key Specifications
- Size: 20 inch
- Thermostat: Adjustable, regulates fan speed
- Speeds: 3
- Blades: 5
- Frame: Metal
- Placement: Window, table or floor
- Dimensions: 4.9 x 20 x 20 inches
| Pros | Cons |
|---|---|
|
|
Things to Consider
The thermostat is the main reason to choose it: set it once at bedtime and it adjusts itself through the night.
Best For
This box fan is best for bedrooms and nurseries.

What to Expect from Box Fans Under $50
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.
For more options, see our guides to box fans under 40 and box fans under 100. If you want a fan built to sit in a window with reversible airflow, our window fans page is another option. The product cards show the current price for each fan.
How to Choose Box Fans Under $50
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.
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.
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.
Look for Safety Features
An ETL or UL listing shows the fan meets safety standards. Fused plugs cut power during an electrical fault, and thermal overload protection shuts down an overheating motor. Narrow grilles help keep small fingers away from the blades.
How We Evaluate Box Fans Under $50
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, motor and controls.
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.
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.
Can I use a box fan in a window?
Yes. Most 20 inch box fans fit a standard double-hung window. Choose one with a weather resistant motor and close the window in heavy rain.
Can I use a box fan with an air conditioner?
Yes. A box fan helps spread cool air from the AC into the rest of the room or the next room, which reduces hot spots.
Final Verdict
The BLACK+DECKER 20 Inch Box Fan is the best box fan under $50, with an 80W copper motor and a 6 ft. cord. For the most airflow, choose the Hurricane Classic Box Fan at 2400 CFM, and for automatic speed control, the shinic 20 Inch Box Fan with Thermostat.
