Best Window Fans of 2025

"I've been using this fan daily, and it’s powerful and reliable. I bought two, and they’ve been running non-stop without any issues. The ability to control each fan independently is a fantastic feature, allowing me to manage air flow easily."

"Living in a sticky Iowa cottage with no AC, I originally bought two Bionaire fans. But I wish I had found the Amazon Basics fan first. It’s quieter, simpler to operate, and doesn’t have any annoying beeps or bright lights. I’m impressed with its quality and price!"

"This fan is really great for its size. It moves a nice volume of air, and I find it fairly quiet at lower speeds. However, I did notice a lack of screening for bugs, which is a bit inconvenient."

"I absolutely love this fan! It's incredibly easy to clean with just a bug screen to manage, unlike my previous fans that required a tedious cleaning process. The remote control feature is a game changer, especially during those late-night skunk incidents!"

"I needed a fan for my bedroom, and I couldn't be happier! The highest speed packs a punch but the lowest is a gentle hum that helps me sleep peacefully. Plus, it fits perfectly in my sideways window!"

"I just got my second Comfort Zone Twin Window Fan. Both fans work great, keeping my kitchen and laundry room comfortable, even at the highest setting. At $45 each, I'm thrilled with my purchase and how much I'm saving on AC this summer!"

"I needed an expandable window fan for my garden shed, and this one worked out perfectly. My windows are 48" tall x 36" wide, so I was a bit worried about the expansion width. I used the two solid expansion panels on the left and adjusted the sliding panel on the right. The fan is relatively quiet and provides great airflow. I love that it fits easily in front of the window screen. Although there are small gaps for insects, my window screen handles that. I would like to see some improvement in the locking tabs since they are a bit tricky to manage from the bottom. Initially, I thought a remote was unnecessary, but I've come to appreciate it. I even considered getting a second one for a dual setup, but now I feel one is sufficient. The price might be a bit higher than other brands, usually around $39, but it’s worth it for the quality. I'm really happy with my purchase!"

"I've had more interactions with Bionaire customer service. It’s frustrating that I have to wait over a month for a replacement unit and that they don’t maintain a waitlist. They do honor their warranty, but my thermostat is defective, making it hard to control the temperature. Even though the unit cools effectively, the customer service has been disappointing. I confirmed the thermostat issue but was told they are out of stock for replacements for six weeks. Not having back-orders is a hassle; I'll have to keep calling to check on availability. While the product works okay, the service policies really diminish the value of the five-year warranty."

"Lo coloqué de manera vertical, ya que mi ventana así lo requiere, y funciona perfectamente. En las noches, cuando el aire exterior es más fresco, baja la temperatura entre 10°F y 15°F en una habitación de 16 m2, lo que me permite dormir muy cómodamente. El nivel de ruido es bajo, un ruido blanco que ayuda a bloquear los ruidos externos. Aunque no es un aire acondicionado, su sistema de inyección enfría la habitación. Además, lo coloqué al muro de la habitación con un brazo para pantalla de TV, y funciona a la perfección."

"I needed three new window fans for home cooling at night during the warmer months. I've relied on Vornado floor fans for years and didn't hesitate to choose Vornado again for these window fans. They are another hit for Vornado! I absolutely love these fans for their sleek appearance and efficient performance."

"I found myself dealing with a suspicious leak in my wall due to improper venting from my bathroom fan. This fan was a lifesaver—it fits nicely in the window and is super quiet. It really gets the bathroom dry quickly, though I do notice that it's not completely airtight and lets in some cold air. Overall, it's easy to use and has been a great temporary solution."

"I miscalculated the width for this fan, but with the included foam blocks, it fit perfectly in my window. It's quiet and has good airflow, although I've noticed it struggles a bit with static pressure if there are any obstructions. Despite this, I find it to be effective for bringing in cool air."

"This unit is exactly what I needed. It draws in cool air and blows out hot air seamlessly. I often use it to prep my bedroom before bed, and the sound helps me sleep. I appreciate that I can leave it in during cold weather, allowing air to flow through the blades without needing to turn it on."

"I love how compact and versatile this fan is. It's been working great for years! It cools in the summer and even helps clear out smoky kitchens. Plus, the white noise it creates is perfect for my sleeping routine."

"Overall, this fan is very effective. It keeps my small room cool and fresh, even on hot days. I’ve drastically reduced my A/C usage since getting it. I do wish the lights weren't so bright, but I can easily cover them with tape. It's a solid fan that I would definitely buy again."

"I find this fan to be of excellent quality and it does a great job of air circulation. The three operation modes are a fantastic feature. I have it set up in an upstairs bedroom dormer window and it fits well with a little adjustment. Although it has a bit of noise on startup, it becomes very quiet quickly. The remote control is super convenient for turning it on and off from bed. Overall, it's a good product."

"This fan is incredibly powerful. I primarily use it for exhaust in a room and it operates very quietly. I have allergies due to dust in the air, and this fan clears the air almost instantly, making it feel as fresh as outdoors. It's a great help for my health and comfort, and I can use it in all seasons except rainy days. I highly recommend it."

"I really appreciate the versatility of this fan. It allows me to control whether it pulls in fresh air or exhausts warm air, which is perfect for different conditions. The removable cover and bug screen are great features for keeping insects out and making maintenance easy. I also love the three-speed settings for adjusting airflow intensity. It’s a fantastic value for money!"

"After trying several fans, I'm thrilled with this one. The remote control is so convenient and I appreciate the lights that turn off after a while. The fan fits well in my window, even with the screen!"

"I'm quite satisfied with my purchase. The airflow is excellent, and it runs quietly at night. I love the design, but I had to use a metal bracket for extra support."

"This fan really impressed me. It effectively cools my apartment and works well mounted vertically. The only downside is that I wish it had a bug screen."

"I bought this fan for my granddaughter's bedroom, and it works pretty well. On HIGH, I get a refreshing flow of air, although it can be a bit loud. The LOW setting doesn't provide much breeze. Overall, I'm satisfied with its performance. I love the ability to rotate each side of the fan, and the feet are a nice touch, allowing me to use it as a room fan too."

"We live in an apartment without AC, and after installing this fan, our room temperature dropped by two degrees in just 30 minutes. It's very powerful, though a bit noisy on the highest setting, which doesn't bother us since we're used to a white noise machine for our baby. Despite being slightly smaller than my window, it still performs well and helped cool our room from 82 degrees to 67 overnight, making it much more comfortable for us and our baby."

"For the price, this window fan is quite nice. I utilize it in a vertical position, and it remains stable. The 180-degree rotating feature is handy since there's no electronic reverse airflow. I deliberately chose this model as it lacks a remote; I control it with a smart plug linked to a separate temperature sensor. My only issue is the two-speed settings; the high setting is quite loud while the low is a bit lacking. Overall, I'm satisfied with my purchase."

"I have this fan in my bedroom window and turn it on at night. It really cools the room off quickly and it's very quiet, so it doesn't keep me awake. Great product for a great price!"

"This has been a godsend this fall. I can't vouch for the durability since I've only had it a month, but it's quiet and powerful. I wish it had the knob style switch rather than the tab at the top and had both in/out modes, which is why I knocked it down a star. However, the air flow is great and I'm satisfied with it."

"I barely fit this fan in my window, but I made it work. My room is so much cooler now. I'm so glad I made this purchase!"

"This fan works perfectly for steam in the shower."

"I just installed it as a bathroom exhaust fan, and I have a good feeling about it. The solid build quality and impressive packaging really stood out to me. I recommend it!"

"The exhaust function is great, but it doesn't circulate air effectively in larger spaces, which was disappointing for the price."
