Review: Reversible electric window fan, works well, intake and exhaust, does the job! - I purchased this for a bedroom window after our heat pump went out and we can't get anyone out to the boonies to fix it so have no air conditioning. This fit perfectly, comes with little legs you can use to just set it on the floor or where ever you want. It only has high or low for settings which is perfect for us as by morning the air gets pretty cold from outside and the window where we put this is right above our head. It is doing a good job bringing in cool air on high during the day and at night we either set it on low or just off since the air can come in any way. It has both intake for cool air and exhaust for getting stale air out and you can set one side for intake and the other for exhaust if you want. Just make sure to shut both fan off before you change the switch to help on wear and tear of the motor on each fan. It does have a button to adjust the comfort levels. The side slider things are a little hard to get adjusted where you want them and to keep them that way or were for me any way. If you need a good window twin blade fan to help keep you cool I recommend this one.
Review: The accordion extenders are garbage, and I ended up cutting them out completely - The fan itself is okay, the reverse buttons work. But I don't believe the potentiometer is connected correctly because if you turn it down between 80% the speed of the fans doesn't change, below 80% the fans cut out entirely. The accordion extenders are garbage, and I ended up cutting them out completely, as another reviewer noted, they are riveted in so I had to use tin-snips and a drill to remove them. I also have a window air conditioner, and I wanted to be able to alternate between using this in the winter (socal) and the ac in the summer. I didn't think my needs were all that specialized when I started this project, and I still don't think they are, but this fan came closest to suiting my needs and I still had to modify it substantially. First problem I had was that there is no way to seal off the fan so that I can use my ac. For this I had to bend some cabinet hinges to shape, and attach them with machine screws to the housing just behind the electronics. Then I cut some acryllic sheets to size, and attached some stick on air conditioning foam to it to make the seal. The next mod I made was to filter the air and keep the rain out. I used the same strategy I've used on other fans in the past. I drilled a few holes in the corners for zip ties, and wrapped the back in foam air conditioner filter: https://www.desertcart.com/gp/product/B00LU28PRW/ref=oh_aui_detailpage_o05_s02?ie=UTF8&psc=1 This stuff has the added advantage of keeping the interior of the fan clean. Once I started using this stuff on house fans several years ago, I never had to clean out the grill on a fan again. Bottom line is I want to see someone release a better product with the following features: 1. Working potentiometer 2. Built in / removable filters 3. Seal-able door 4. Working accordian extenders. This still gets 4/5 stars though because it's a better fan than all the others I researched.

### ⭐⭐⭐⭐⭐ Smokers Porch exhaust for 7 years
*by B***N on November 27, 2021*

Recently ordered my 2nd Lasko twin fan to replace the previous one. Previous one lasted 7 years while running 50% of that time. It was used on an enclosed porch window where my wife smoked. The fan, located in southern Indiana porch, 150 sq. ft. in size, in a eastward facing window, exposed to an average of 40" of rainfall a year. The fan had to be cleaned every year from the dust and elements of weather exposure. The construction is plastic and stainless screws holding the body together. The screws are phillips. One can remove around 10 screws and open the fan to expose its inners. I eventually modified the fan controls. That is because the fan would not turn during cold or cooler days. Apparently the fan is setup to run when the temperature is warm or hot. Making the purpose of this fan to cool a room. Even dialing the thermostat all the way down was not enough during winter months. I eventually removed the temperature rheostat and hot wired it across because we wanted the fan to turn regardless of the temperature on the porch. This thermostat removal worked well for us for many years and smokers could smoke and the porch be clear of smoke in an hour or so. The plastic is tough enough for a fan that will probably fail in less than 10 years. The accordion slides on both sides seem a little cheap but they lasted the 7 years while being exposed to rain and sun weather. The fan seems to make very little noise on low. However on high, there are significantly more noticeable sound of fan blades cutting through the air. I have seen comments about the sound and the volume of air movement. It does not move a lot of air. The Cubic Foot per Minute is not listed anywhere. But it is enough for us. After 7 years, the main Low/High/Off switch failed. One fan barely turned, the other was significantly slow. It was time to be replaced.
