There's nothing worse than being stuck in a place with no airflow or with stagnant air. The solution? Add a box fan! The best box fans quickly alleviate such discomfort and today's models are lightweight, powerful, and quieter than ever. We've assembled plenty of options for every situation; check out our list below and see which fan fits into your environment.
PELONIS 3-speed box fan for full-force circulation
Boosts AC efficacy
High-performance blades and three speeds make Pelonis' box fan the ideal booster to a weak or overtaxed air conditioner. A safety grill protects your fingers, and it's light enough to carry from room to room. It's equally at home on floors, tables, and windows, and the recessed storage space for its cord keeps surfaces neat and doesn't add to existing cord clutter. Pelonis designed this box fan with a slim frame in monochromatic black, so it adds a little panache to your aesthetic instead of sticking out like a sore thumb.
Vornado 573 small flat panel air circulator fan
Optimal airflow
Vornado's specialty (and namesake) is vortex-intensified air circulation across entire rooms. Quality, longevity, and efficiency are key benefits of their products. This small flat-panel box fan (also available in medium and large) has three settings and a tilted head with a spiral screen that creates multi-directional airflow. Even the smallest size sold is no slouch; it will produce a robust, 60-foot airstream.
OPOLAR 8-inch box fan
Emulates real wind
Ultra-quiet sub-40 decibel output, four speeds, and 1800 max rpm grace this portable desk fan from OPOLAR. Timed modes help manage your fan even when you're asleep; the available interval settings are one, two, four, and eight hours. It's USB-powered for convenience but still ships with an AC wall adapter. The "natural wind" feature is its best one; the oscillating intensity mimics the ebb and flow of a true breeze.
Genesis 20-inch max cooling box fan
Fits on any flat surface
Stabilizing feet and lightweight copper construction help this 20-inch box fan by Genesis stand firm as it cools your space. Its longevity is significant, thanks to the copper motor; it runs faster and in any weather. Designed to complement décor instead of clashing, the sleek white frame and grille will fit right in.
SLENPET 20000mAh rechargeable fan
Great for camping
One of the downsides of camping or spending time outside in hot weather is the lack of air circulation on a still day. When the wind doesn't show up, SLENPET's portable, rechargeable box fan has your back. With its ultra-high capacity 20,000mAh internal battery, you can cool off your tent for nearly a week uninterrupted. If your campsite's plenty windy, that battery can provide up to five full smartphone charges instead.

The best box fan for your particular needs will depend on the situation—will it fit in your window, or is it lightweight enough to take to another room? Also important to consider is how many speeds the fan offers for greater breeze variety. Pelonis' 3-speed box fan works in tandem with air conditioners to maximize airflow and make them more energy-efficient. Its 20-inch dimensions allow it to fit in narrower windows as well.
If portability is what you're looking for, consider Vornado's small flat panel box fan or SLENPET's portable, rechargeable box fan. Vornado's fan has stronger airflow output, but if you're out in a remote area camping, SLENPET's high-capacity battery can prove beneficial in emergencies, making sure your mobile or GPS devices are charged.
