Keeping cool
5 out of 5 stars
Keeping cool
These fans do a good job of moving the air. They are fairly quiet on low. I don't use the thermostat at all on it. They seem to be built fairly well and only time will tell how long they last. If you have vinyl windows here is a trick to putting the fans in: I used the the two feet that came with the fans and put them inside the sill of the window. I then put the fan in on top of the feet and expanded the panels. After that I lifted the fan and took out the feet and put a 3/4" x 3/4" x 16" piece of wood and lowered the fan onto the wood. This way it keeps it off the horizontal piece of the window. I like these window fans a lot and if I had to buy them again I would.

    The media could not be loaded.
    I wanted a decent window fan for the fall and especially the spring to draw the cool air in at night when there is no breeze. I have only used this fan a few times, but it seems to be doing that job so far.

    I have enjoyed using the temperature settings so that my room doesn’t get too cold at night. I have noticed that if I set the temperature to 60 degrees, it really means 65. In my video, you can see when I use the temperature settings, the fan runs at 60 and shuts off at 65 even though the temperature in the room was about 67. I also noticed that the fan shut off one night when I had it set to 60 but the room temperature was about 67, and I think it was because it was so cold outside at 30 degrees. I imagine the fan can’t read the temperature inside the room when it is significantly colder on the windowsill where it sits. I don’t really mind this discrepancy, though, because I like my room close to 65 degrees at night, and I can still achieve this so far by setting the temperature at 60.

    I love that it is so easy to change the direction of each individual fan with the flip of a switch, as you can see in my video, and I have been running it with one fan blowing in and one blowing out. I personally don’t find the noise from the fan irritating, though to be fair, I have another fan in the room that drowns out the noise of this fan somewhat. It isn’t the most powerful fan by any means, but for a smallish window fan, I think it has decent power, enough that it has affected the temperature of my room. As other reviewers have made clear, this fan does not come with a remote, and while that would be a lovely perk, I won’t count it against the fan since it was not promised to me and it is not a necessity for my needs.

    I am happy so far. Based on reviews of these double window fans in general, I am a bit worried about durability, so if this fan stops working in some way or otherwise disappoints, I will try to return to edit my review.

    I bought this fan around 10 years ago. This page says when I last bought this item, so I know this. Otherwise, I wouldn't know when I bought it. I do know it is still working as if it were new, except the sliders that reverse the direction of the blades have fallen off. I can still reverse the blades but its not as easy i need to use a butter knife or something. I don't remember losing them. I have just been turning the fan around. Maybe they fell off during storage and I didn't notice. I've been using it every summer and it shows no signs of failing.

    I received the much needed window fan today. The durability is spot on.l love the clean , sleek lines that accommodate both vertical and horizontal windows. I love the powerful breeze that it provides going out / and or coming into your space. To set a temperature on thermostat it will only operate on high speed until the desired temperature is reached. But you can manually control the speed settings if you do not use the temperature control.There is a hum as I have read in other reviews. Only my fan is humming in intervals . The best way to describe it is , it sounds like gears switching. I did call the company about this odd sound. Unfortunately it has progressed and I must return the fan . I am not sure if this is part of the motor function or just what I figure is a defective unit. It’s unfortunate, however because it really is a nice looking window fan. It comes in the actual manufacturer box. I did not try the accordion on each side so I can’t comment on that feature. The fan has a slide button for each separate fan so you may have air going out or coming in. Very nice for the price but I am afraid to replace it with another as this may be the product’s built -in sound system.Humming in intervals?

    ***UPDATE after one month of use*** I stand by all the details in my review below...but just want to add: I could not be happier with this fan. It appears to move more air--with less noise and more speed--than my old work horse Honeywell fan that I was replacing. If I had the choice to repurchase this fan...or my old Honeywell...I would choose this fan.
    ***********************************************

    This fan replaces my inherited Honeywell dual fan (it was at least 30 years old...probably older). It was powerful...and was made when most fans were still made with metal blades. Consequently, it was very powerful for its size. As far as I'm able to tell fans of this style are no longer made with metal blades. The modern version of this fan appears to have been discontinued. I used my fan mostly to cool my bedroom by setting it for exhaust in the window of another room... with the windows in my bedroom open. It was very effective for this and on all but the hottest nights allowed me to turn my A/C off. Using a fan to draw air in this way requires a fan with a high CFM rating.

    I looked at a lot of the fans of this style that are being made today. None have all the significant features of my old fan. This fan had most of them...reversible (with the ability to have one fan exhausting with the other drawing), locking expandable side panels to give a good fit (important if you are using for exhaust), and a high cfm capacity. Many of the fans now made don't even list their cfm rating...this one is listed at over 700. (By comparison the new Vornado Transom fan--that many sources are rating as the best window fan--only moves a measly 80 cfm. I have one of these...and I love it for certain things. But it is completely unable to move enough air to cool a room as I describe above.)

    The main thing this fan doesn't have is the ability--when using for intake--to direct the airflow for each of the fans with rotating grills. I LOVED this feature on my old Honeywell. No fan currently being made--as far as I could discover--has it.

    I would prefer that it didn't have the bright LED lights. But I can live with this. If I were keeping the fan in my bedroom, this would bother me.

    In the comments for this...and similar fans...there are a lot of complaints about the "cheap plastic." Fans are plastic now. This will always feel flimsy and insubstantial...particularly in one that is supposed to be light enough to sit in a windowsill. This one feels pretty normal in that regard.

    The comments about noise level are all over the map. Fans are noisy. I didn't see a decibel rating on this one...but I found this one to be less noisy than most.

    There are also complaints that it "doesn't cool." Fans don't cool. They move air. This one excels at moving large volumes of air. If you are trying to get cool air in...or hot air out... it does the job well.

    5.0 out of 5 stars GREAT for 3D printing ventilation
    Reviewed in Canada on July 28, 2023
    First impressions are good. I bought this to ventilate my room while I 3D resin print. Although my 3D machine has a built in ventilation tube (as shown in pictures), the room still builds up fumes when printing, while i’m cleaning the prints and when I haven’t poured out the resin into it’s containers.

    This fan works great as it can suck out air in the room. I will eventually make use of it during the summer if rooms need to be cooled, since it works well with bringing in air from outside. The design could be tweaked, very minor but I wish that the temperature on the fan was displayed in Celsius too, only Fahrenheit temperatures are shown.

    I especially liked how it fits vertical and the extenders stretches enough to fit snug on my windows. In the pictures I have to make room at the bottom for the ventilation tube for my 3D printer, but the fan does stretch all the way down.

    As for sound, it’s comparable to a normal fan even on high.

    As for sound, it’s comparable to a normal fan even on high.

    Lots of people are complaining about noise here... I don't get it. I've had it a month and it sounds like a fan. Some of the new tower fines are more silent but if you've grown up with fans you know what a typical fan sounds like. And this fan is no different.

    I bought it because of the legs option. My exterior walls are floor to ceiling windows with a single small slider window in the middle that's around 30" wide and 16" tall. I figured I could use a table in front of the slider window if I couldn't get it to fit. It fit perfectly.

    Although I have central air conditioning, I really like fresh air and with the ability to set one or both to push air outward or inward it has been terrific.

    With all the wildfire smoke this year I have been using it 24hrs a day to clear the air out and bring none in. It's been awesome.

    Got my fan today in preparation for summer and installed it into my window. The accordion wing 'tabs' that lock it are very difficult to open, I had to pry them to expand the wings to fit the window but it fits great. The second issue I noticed as I turned it on (low setting) was that it is extremely loud. I put it down to the 'turbo velocity' in the description?! I don't know, I'm not in any way an expert on what size motor runs what and the expected decibels would be. But I have purchased and used a lot of these types of fans in the past because I do not have air conditioning to rely on to stay cool during the hot summer months. I have tried Bionaire and Comfort Zone window fans, and they are quieter running on 'high' than this fan is running on 'low'. I chose this fan because of the price difference, this one was cheaper by about 30-80$ than the others that I was looking at.

    On the good side...I have noticed that this fan pushes much more air than previous ones I've used. It is more powerful. I have a large living room and can feel that it is much cooler in here after 15 minutes of use on the low setting in exhaust mode. It works in all functions and the buttons seem sturdy as this one does not have a remote. The colour is a bright white which looks nice in the window and fits in place even with my screen still in; so no bugs. So if you need it in an area where you won't be sitting right beside it like me, I would recommend this purchase as it does as it is supposed to very efficiently.

    5.0 out of 5 stars Cool Air And Coloured Indicator Lights. What More Could I Want ?

    I got this fan to replace a faithful servant of far too many years. Plastic doesn't last forever. :-) This is an upgrade in ever way.
    I can't compare this to any other fan available but I can say, I'm completely happy with the form and the function of the Genesis fan which does everything such a product should do and does it effortlessly.
    Finally cool air without any intermittent sounds of distress as from my old fan, :-)
