The 6 Best slim Window Fans (2023 reviews)

Holmes has been making great fan for years, thanks to a combination of clever design and high-end materials. It cools the house so nicely at night. It is not real strong but brings outside air in and cools the room. The twin fans are very powerful and being able to switch between intake and exhaust is great. When using this as intake, in the bedroom, or alone in the kitchen, during warmer days, it actually keeps the apartment cool. It is designed to fit windows with minimum openings of 25 in wide and 12 inches to hide. The three speeds work very well.

This fan is easy to clean, quiet, and never any rattling because Holmes products are well built to last. The thermostat and reversible motors make it a must-have for summer time. It takes longer for it to cool off the room.

Two 6 blade fans, independent speed & directional controls & a thermostat

Best For small room: Vornado slim Window Fan

The vornado slim window fan's material feels more premium than its price would suggest. This fan brings fresh air in, pulls stale air out when you set it to exhaust. The air flows fast, cool and constant to create a cooling experience unlike any other. It measures the inside air temperature, so it can be set to run until a temperature is met. It will also display the room temperature, and the thermometer icon in the fan will be illuminated green.

The built-in Alexa feature is incredibly convenient. The foam blocks included to shrink the window opening to snuggly fit the fan are also sturdy, easy to install, and well made. It is great for cooling air in the summer.

Best For Window sill: sharper Image slim Window Fan

Buy on Amazon

The sharper image slim window fan should be able to handle its purpose and duties with ease. The fan itself is decent and looks a lot more stylistic and modern than most basic window fans you normally see. It provides good air flow and is relatively quiet. It’s relatively quiet and even on the highest setting, it’s not overly loud. The edges of the fan unit are not square therefore when the butt the inserts up against the side you have a very nice bug doorway all you need is a little food for them and you can take some nice pictures.

This is easy to install in a window and it blows air fairly well in both directions, into the room and as an exhaust from the room. The LED lights are bright so you can see what speed you are running. The power cord is a good length if there happens to be a plug under the window.

Why We Like This:

Serves to both pull air in and as an exhaust fan
You can adjust the speed of the fan by pushing
One of the new comers and featured product

Best For putting Air: sharper Image Window Fan

Buy on Amazon

You will love this fan when it’s in use on those nice summer nights when it’s between 65 and 72 degrees with low humidity. The button activated exhaust function is the best. It has a very nice style and functions great. It has three fan settings that are all quiet. There’s no refrigerant or anything remotely close inside of it that’s going to have your room bone-chilling cold in 90 degree hazy, hot and humid weather.

The fan moves plenty of air as a fan or as an exhaust fan. The controls are easy to use with push buttons. This is chunkier and heavier.
