Honeywell Twin Window Fan

The Honeywell Twin Window Fan, HW-305 is a small but powerful fan. It doesn’t have a large number of features, but it does have the ones that really matter. The blades are reversible for switching from intake to exhaust with just the flip of a button, and it has a manual thermostat that will automatically turn the fan on and off for your perfect level of comfort.

Installation is a bit more painful with this fan that it would be with most others. The extender panels don’t include an accordion style extender that is easily adjustable to any length. Instead, the plastic is rigid, and one of the panels must be adjusted and then held into place with a pair of small screws. This does make the panels easier to clean than the accordion style, since they don’t collect as much dust and can just be wiped off with a cloth, and they also look nicer, but it takes more than a few minutes to get it installed.

There is a built-in carrying handle at the top of the fan to make it easy to carry and store when you want to move the fan. A great bonus for this fan is that it is built with a rain resistant motor so owners don’t have to fret as much about forgetting to take it out of a window during wet weather, even though it’s easy to move.

The control panel is very easy to use, with only two knobs for temperature and speed, and one switch for intake/exhaust. The manual thermostat has no temperature readout makes for a bit of guess-work when setting the fan to the desired room temperature, but the dials are self-explanatory. The thermostat is also less sensitive because it’s manual and therefore less likely to cycle on and off several times a minute, which can be annoying with digital models and there is no lit LED screen to cast an annoying light in a dark room while trying to sleep if extra light could potentially be a bother.

It’s difficult to clean the fan as the front grills collect a lot of dust and dirt and it doesn’t disassemble very easily for washing. But overall it’s a good no-frills fan that will do the job that matters. The power of the HW-305 is great. It trades all the extra functions and knobs for what really matters–air movement.

  • Included additional side panels will fit most slider and double hung windows
  • Electrically reversible blades for intake or exhaust with just the switch of a button

Optimus F-5285 8-Inch Electrically Reversible Twin 3-Speed Window Fan

A great feature of the Optimus F-5285 8-Inch Electrically Reversible Twin 3-Speed Window Fan with Thermostat is that each blade has its own control, not just for intake and exhaust, but also for power and speed. If two fans are too much, one can be turned off. The fans can also be set to circulate air with intake blowing harder than output or intake blowing softer than output. This is great for exhausting rooms with uneven heating in the winter, while still leaving the option to bring in a little air without over cooling.
The built-in adjustable slide screens with locks work very well, stay in place and snap into the window with ease. It has a very sleek appearance, with clearly marked controls that really don’t need any explanation at all to make use of every feature this fan has to offer. It also has a rain resistant motor, which is very useful if this fan is being used in a humid climate that sees a lot of rain. The fan won’t need to be taken out and reinstalled every time a slight drizzle occurs.
The Optimus F-5285 has removable feet, so if it won’t fit in front of your window screen, it can still be used by placing it on the window sill with the screen in to keep bugs and dirt out of the room. The feet also come in handy for windows that are slightly too small for window fan installation.

The manual thermostat works well, and gives the option to maintain comfort in the room without the annoying constant on and off of digital fans. There is no lit screen or LED read out for nighttime use, but this is nice if the light of an LED screen would otherwise disturb light sleepers. Low and medium settings and quiet enough not to interrupt sleep as well. In fact, the low setting is so quiet it can barely be heard at all.

The fan trades quietness for power. It’s more suitable for smaller rooms because it doesn’t blow as strong as other window fans with 8-inch blades. But the fact that it has removable feet also makes this fan perfect for desktop use where heavy blowing power isn’t needed. The airflow won’t be so strong as to overwhelm the user, and can be tailored with the individual power, speed and intake/exhaust buttons for a very comfortable desktop environment.

Product features

  • Independently reversible blades for intake, exhaust or air exchange
  • Independent power and speed controls for each side
  • Rain resistant motor
  • Three speeds for perfect comfort
  • Manual thermostat to maintain room temperature
  • Expandable screens on both sides of the window for centered placement
  • 8 inch blades for increased air circulation
  • Removable feet for floor, table or window use

Optimus F-5286

The Optimus F-5286 8-Inch Reversible Twin Window Fan with Thermostat and LED has almost every feature that should be expected in a higher model window fan. Easy to install with adjustable expanders on both sides of the unit, this fan will be out of the box and cooling a room to perfect comfort in no time.

Window grabbers at the front and back of the top hold to the window very well without being obvious in appearance. The sliders work well for fitting to the sides of the window. There is a small gap at the bottom and top of each side that could sometimes let small bugs and dirt in, but it’s not an overtly large problem. The fan also has removable feet that are very stable for use as a desk fan or floor fan, or placement on a window sill without removing the screen.

There are a lot of buttons on the Optimus F-5286, and they are not quite as self explanatory as they should be. A quick review of the instruction manual will add a little time to the initial installation and use. The blades can be individually set to intake or exhaust, or one each for circulating stale air out of a room while bringing fresh air in. They can also be individually set to run on high, medium and low settings. The ability to independently control each fan is very nice.

The thermostat can be set to cycle the fan for a comfortable room setting. It can only be adjusted by five degree increments between 65 and 80 degrees, and the highest setting is labeled as MAX on the thermostat section, so users have to punch the temperature adjustment button up to five times to get to that setting. The LED light also blinks, which is can be annoying at night time, but other than that it is quiet enough not to disturb nighttime sleep, or conversations and television use during the daytime.

The rain resistant motors allow the Optimus F-5286 to be used in a window that might be exposed to some moisture at times without having to uninstall it every time it rains. The rain resistant motors along with this fan’s ability to control intake and exhaust individually as well as speed, the adjustable timer, adjustable thermostat and quiet operation make this fan ideal for small to medium rooms that need extra cooling or circulation with just the programming of a few buttons and no further thought.

Product features

  • Adjustable extenders on both sides for the perfect fitting in slider, double hung and casement windows
  • Rain resistant motor for use in a humid environment
  • Adjustable thermostat in five degree increments for perfect comfort
  • Electronically reversible blades for intake, exhaust or circulate
  • Independent speed controls for both sets of blades
  • Programmable timer
  • 3 speeds on each fan for optimal circulation

Comfort Zone CZ309

If all you need is a very basic fan to either bring air in or exhaust air out of a stuffy room, the Comfort Zone CZ309 9-Inch Portable Twin Window fan will do the job. It’s a very basic, inexpensive fan so it doesn’t come with all of the bells and whistles that more expensive models have. It’s lightweight, at just 6.4 pounds, and has a very convenient carrying handle, so moving it from room to room is easy even if you have trouble lifting most things.

The accordion style extender panels lock in place well and are located on both sides of the fan, which gives you the ability to center the fan exactly as it’s needed. The portability features also make it a bit less of a hassle to reverse, since this has to be done manually by taking the fan out of the window and flipping it around. The placement of the cord is a bit awkward and causes the fan to sit a little less flush against the window’s frame than it should so it may take a little moving around to get it to set right.

This fan has two speeds, which are controlled by its only knob located at the very top of its frame where the bottom of the window rests on the fan, but you can access this button whether the fan is placed for intake or exhaust.

The fans 9 inch blades are larger than what is found with most window fans and usually good for moving more air, but when combined with the lighter weight materials used for its construction, they result in a little more vibration than would be experienced with a heavier fan. It will move plenty of air for a small room, but won’t produce a strong air flow feel in medium or larger rooms. It’s fairly good for use as an exhaust fan to take cooking fumes out of a kitchen, exhaust fumes out of a garage or excess humidity out of a bathroom. It’s also great to double as a desk fan with its included removable feet, and will produce a very nice flow of air for that use.

Overall, the Comfort Zone CZ309 is a basic, no-frills window or desk fan that will add a little extra air flow where you need it most.

Product features

  • Adjustable to fit most windows with built-in extender panels on both sides
  • 9-Inch blades for higher volume of air flow
  • Carrying handle and lightweight construction for portability
  • Manually reversible for intake or exhaust
  • Two speeds
  • Simple to use and install
  • 1 year manufacturer’s warranty

Optimus F-5280 7-Inch Twin 2-Speed Window Fan

The Optimus F-5280 7-Inch Twin 2-Speed Window Fan is a completely basic fan. It’s ideal for use as a back up fan where a box fan just wont do by itself, or use in a small room to bring in extra cool air. It also has a lot of nice features despite its simplicity.

The extender panels built into both sides are easy to use so that the fan can be perfectly centered in double hung windows. It’s smaller, at 22.6 inches, and not as tall as many window fans, so can be fitted for more narrow bathroom and kitchen windows. The motor is rain resistant so it will not die at the first sign of humid weather, and it handles continuous use on high speed very well. These design features make the fan especially ideal if it is being used for ventilation to remove excess humidity from a bathroom.

For windows that cannot fit a traditional window fan, the removable feet can be used to place it on a window sill instead. This also allows the fan to double as a desk fan or a floor fan for smaller rooms. Moving it around isn’t a problem as it is light and fairly easy to handle, although it should have a proper carrying handle for this purpose. The plastic seems a bit flimsy, and it looks a little cheaper than other window fans do, but it holds up to being moved around a lot. The feet are rubberized as well, which keeps it from getting knocked around while it is being used as a desk fan.

The Optimus F-5280 only has one knob for power and its two speed settings, so there won’t be any fiddling with controls or worrying about lights that interrupt sleep. It would be nicer if the fan had controls to reverse airflow, rather than having to take the fan out and flip it around, but the controls are on both sides of the unit, so once it is placed, it can be turned off and on with ease. It will also have to be turned off in the middle of the night if it gets too cold since there is no thermostat.

This fan is definitely powerful for its price, even more so than some fans with larger blades, but it’s also much noisier than many window fans. This is good if the white noise is useful for drowning out background sounds, but bad for use in rooms where the extra sound might interfere with conversations or watching television. This fan is absolutely great for use in a garage or shop where it can be run continuously on exhaust mode to draw out fumes and odors.

Product features

  • Two speeds, high and low
  • Speed controls on both sides make the fan manually reversible for exhaust or intake
  • Rain resistant motor for operation in humid environments
  • Removable feet for table, floor or window use
  • Adjustable screens on both sides of the fan for easy fitting
  • Fully assembled for quick installation

The extender screen makes the Bionaire BWF0522M Thin Window Fan very easy to install and set up in your home. This model is 3.4 x 25.2 x 7.7 inches and weighs 5.1 pounds. Even with its smaller design, this window fan is more powerful than previous models and can cool any room down quickly and efficiently.

Powerful and Compact

The Bionaire BWF0522M Thin Window Fan has three speeds for maximum comfort. Its manual controls are easy to use and adjust to get just the right amount of air flow into a room.

The Bionaire BWF0522M Thin Window Fan is also designed to be quiet while still moving a large amount of air through any room in your house.

Conclusion

Most customer reviews highlight the Bionaire BWF0522M Thin Window Fan for its quiet, efficient, and easy-to-use attributes and rave about its overall functionality. The smaller design also impressed many customers as well as its easy installation and flexibility when fitting into windows. Even lighter than its predecessors, weighing in at about five pounds, the BWF0522M model packs a punch that can fit vertically or horizontally in almost any window of the house. The manual thermostat also is a well renowned feature that does not have the bright display of digital displays, but is still responsive and easy to set.

The low and medium settings turn off a couple fans in the unit, rather than making them spin slower, as in previous models. This means your window essentially becomes open when running the fan on lower settings. The fan is so quiet on high, however, that most customers concerned with bugs entering the house through the window simply run the fan on high. Some previous models have been difficult to install in certain windows, but the new BWF0522M model improves on this design and makes it easy to install and get up and running quickly and quietly. Overall, customers are satisfied with this wall fan due to its air speed, size, and quietness.

Lasko 2138

The powerful motors of the Lasko 2138 8-Inch Electrically Reversible Twin Window Fan make this fan perfect for use in any room. It will even cool down large rooms with reasonable efficiency. The independent controls for both blades allow this fan to be tailored to any situation, whether cooling, exhaust or circulation is needed, and it can be adapted even for desk or floor use with the removable feet.

This fan is nicely quiet for the power and seems able to run non stop without many problems, but it does come with a manual thermostat that allows the fan to turn off once the room reaches the desired temperature. Setting the temperature is a bit of guesswork since there are no readings on the knob, just low to high, but turning it down a bit once the room is cool enough will adjust it to the right setting. The manual thermostats are much less sensitive than the digital type, which is a plus if you don’t like for the fan to circle on and off too often.

There are only two speed settings to this fan, and it would be nice if there were three since high has such a powerful blow but low may not be enough for some comfort levels. There is definitely a very detectable difference between the two speeds.

Window installation is a bit more of a hassle, as the E-Z-Click extender panels may take a bit more work and fuss than the name implies, the problem being that they don’t always stay in place. A pair of screws are included, but they are small and difficult to work with and turning them too hard can easily strip the plastic. This makes installation into windows larger than 30 inches a bit of a headache, but if the fan isn’t moved much then the individual intake/exhaust/circulate buttons for each side make this a one time hassle since the fan doesn’t need to be manually flipped. It also lacks a groove on the top and bottom that make other fans fit more tightly to the window and sill, but this is surprisingly less of a problem than it appears to be at first notice since the fan sits well enough once the window’s edge is placed on the top.

If a kitchen only has one window, the fans can be set to circulate, with one blowing in and one sucking the odors out. It clears the room just as fast as opening a second window and brings plenty of cool air in while it works because the airflow is much stronger than most window fans.

Another great use for the Lasko 2138 is to keep computers cool while working at a desk. The exhaust function is strong enough to pull plenty of hot air away from the back of the computer and keep it purring along. Also, one side of the fan can be set on exhaust to pull away the hot air while the other side is set to intake to provide a little relief for the user. The power, durability and versatility of this fan definitely make up for the small design flaws with the extender panels.

Product features

  • 8-inch blades for strong air movement
  • Fans can be independently reversed for intake, exhaust or circulate
  • Adjustable to fit most slider and double hung windows 25 to 35 inches wide
  • Manual thermostat for perfect comfort control
  • Removable feet for floor, desk or window use
  • Quiet operation
  • Two speed settings

Lasko Twin Window Fan 2137 Review

Lasko Twin Window Fan, 2137

The biggest advantage of the Lasko Twin Window Fan 2137 is that it will actually fit into the smaller windows, even down to 22 inches and is unbelievably easy to install. It’s adjustable, accordion style side panels will fit windows up to 34 inches without the need for extra panels or adapters.

Get more information and buy now on Amazon.com >>>
This fan is thin enough to be used with the window screen still installed, which it recommended since there is no built-in dust screen to block dirt and bugs from entering the home through the grills. The window grabbers built into the top give a secure fit for the fan to the bottom of the window. It is very light and weighs only 5.8 pounds so it’s easy to move, but it would be nice if there was a carrying handle or a built-in carrying groove.
The plastic that the housing it’s made of is not very expensive looking, and somewhat thinner than the plastic used with other models. It also bends a little too easily at the touch. It looks fine despite this, with a simple white color, and the adjustable extenders on both sides of the fan to make it possible to center the fan in the window for a nicer visual appeal, which fans with rigid side panels can’t do.

The fan’s only knob is at the top, flush with where the window sill fits against the top of the fan. This makes it very difficult to turn the knob when you want to turn it off or change the speed because it’s just too tall and bumps the bottom of the window. But the knob can be accessed from both the front and the back to make it manually reversible, just pull it out of the window and turn it around to change from intake to exhaust.

The Lasko 2137 can also be used as a desk fan or floor fan with the removable feet. It won’t produce as much air movement as a typical box fan, but it still comes in handy, especially as a desk fan, for which it provides plenty of power.

Bionaire BWF0910AR-WCU Remote Control Window Fan Review

The Bionaire BWF0910AR-WCU Remote Control window fan is definitely solidly built for such a light fan, weighing in at only 8 pounds, and well worth the price. It’s larger blades move much more air than most window fans and are comparatively whisper quiet.

The electronically reversible blades can be set to intake, exhaust or circulate with just the push of a button to create the perfect environment in your room. Additionally, the power of this fan makes the circulate mode much more effective than most dual fans. It is rare to still feel a very nice, powerful breeze while a dual fan is in circulate mode.

This  Bionaire BWF0910AR-WCU Remote Control window fan has a digital thermostat that can be programmed to turn on or off for the desired temperature in your room. In addition, it has a separate button for auto mode vs. manual mode which saves the trouble of going through six settings to switch between manual and auto functions, unlike some other digital models. Users can tell that the fan is in auto mode by the red indicator light at the top of the control panel.

The included remote control can be used to turn the fan on and off or change the temperature setting without getting up. Unfortunately, the mode button is not on the remote, so switching the fan from automatic to manual mode will have to be done from the button on the control panel.

I found 51 customer reviews at the time of writing and they had awarded the Bionaire BWF0910AR-WCU Remote Control window fan 4.4 stars out of a possible 5 on average.
See all customer reviews >>>

Conclusion

One other small drawback is that it’s larger size of 25.5 inches won’t allow the fan to fit some smaller vertical windows, but it will fit most standard windows with the included extender panels and adjustable extender screen.

Like other models of Bionaire fans, the BWF0910AR might have some issues with the thermostat as some unit’s heat sensing wires are placed a bit too close to the motor, but the remote makes it so easy to program that the room temperature can be adjusted with a little guesswork.

A very nice bonus is that the brightness of the temperature display can be dimmed to prevent it’s light from interfering with your sleep if you are sensitive to that. This fact, coupled with the very quiet operation and remote control makes this fan absolutely ideal for nighttime bedroom use.

Holmes HAWF3095-U twin window fan

Holmes HAWF3095-U twin window fan

This fan may be a bit too deep at 5.5 inches to allow some users to keep their window screens in, and the expandable adapter doesn’t sit quite evenly with the rest of the unit. There is a small gap between the bottom of the adapter and where it is supposed to meet the window. It also doesn’t have a built-in dust filter or closable vent, so it’s best to make sure that this fan will fit in front of the window screen or take it out when it’s not in use.

Get more information and buy now on Amazon.com >>>

Easy Installation

Installation is very easy. It includes adjustable and snap on extender panels and has a very secure fitting design. Fan dimensions are 25 inches by 13 inches, so it won’t fit  the smaller windows, but it will fit even many types of casement windows with a specifically designed bracket that the manufacturer can provide.

The mode button turns the fan on and cycles through three automatic temperature settings. The temperature can be further fine tuned in one degree increments with the two additional temperature buttons. There is no remote with the holmes HAWF3095-U twin window fan, so you have to rely on the thermostat if you want the fan to turn off at night when it gets too cool. When it cycles on and off, the noise is not too disturbing as this is definitely one of the quieter fans on the market.

You can’t just run one fan at a time or individually control their speed, but you can adjust the  fans individually with slider switches to intake, exhaust or one fan doing each for air circulation. This mode is very nice for cooling off a room while removing stuffy air and odors, especially in a hot kitchen while cooking on the stove or using the oven. For bedroom use, it’s good to have the fan on intake at night, and exhaust mode during the day if it’s much hotter outside than it is inside.

  • Adjustable to fit most double hung and slider windows

Conclusion

Sometimes, when the room temperature reaches close to the desired setting, this fan’s digital thermostat can cause the fan to cycle on and off rapidly, as often as two or three times a minute. If this becomes annoying, the timer function can be used instead. For instance, if you want the room cooled when you first go to bed, but you know that the temperature is going to become too cold to keep running the fan around midnight and don’t want the chill to wake you up, you can simply set the timer for it to turn off. The timer can also be set to turn the fan on a couple of hours before you return home without having to run it for the entire day. This makes a nice feature to get a house ready for the owners to return without wasting electricity.
