Easy to install, fan is quiet and powerful. This was perfect solution to a kitchen where externally venting exhaust fan had been replaced by an over-stove microwave with internally filtering fan--useless for serious cooking. Better looking than the usual two-fan window unit and easier to keep out bugs. Foam blocks included to fit unit to window.

4.0 out of 5 stars Great looking design works well.
Reviewed in the United States on September 24, 2023
Color: WhiteStyle: PORTALVerified Purchase
Airflow into the room works great and is nice and quiet. I don't understand from other reviews people struggling with the foam spacers. Just put the first spacer in place and push the unit up next to it to hold it in place. The air shutter mechanism was jostled a bit in shipping and the unit made clacking noise when first turned on. This was easily fixed by sticking a screwdriver through the air holes and pushing the shutter up and down until it's aligned again. Works perfect now no noise. Fits great in window with built-in screen. It's nice to know that I can still use the screen to keep bugs out with the unit in the window. My only negative is the suck air out of the room mode does not have a lot of air flow. It's nowhere near as strong as the blowing the air into the room.

3.0 out of 5 stars You’re Paying For Design, Not Fan Blow/Exhaust
Reviewed in the United States on May 24, 2022
Color: WhiteStyle: PORTALVerified Purchase
I did read all reviews. And I hesitated to make this purchase simply due to cost. But I was hopeful. And knowing some negative reviews are written due to not reading directions or just to be negative I took a leap and bought 2.

We need 2. We have wide open air flow in all 4 sides of the home due to being on a 100 acre grape farm. And we live on a huge lake, reviving west winds daily without fail. But we do have an older home where air flow was not considered back in the 50s. Having 2 fans to pull in cool air in the am and exhaust warm air late afternoon/evening is essential to keep the house in our comfort zone.

Those $25 box fans at Walmart are excellent due to force of air movement. But they don’t fit in windows and they are beyond tolerable with noise. The $50 dual window fans are ideal as they exhaust and pull in air but not with a switch - you have to manually reverse them, they take up 2/3 of window view and allow rain to enter the home thru the vent. Yes, we can use AC but in our state, the first $100 of the bill is all the fees and the companies have elevated their pricing over 30% in last 2 years. So, we need two fans that bring in the air but also exhaust it to stay within our budget.

1- These fans DO work. We can’t find anything negative to say about that. During a warm day I reversed 1 fan facing west to exhaust warm air and pull in the cool AM air. It was 82 outside, 68 inside. Very comfortable. By midday, it was warming up inside so I started the 2nd fan. It was 86 outside, 72-74 inside. Still very comfortable. In the evening as the sun set, we reversed the air flow of both fans to bring in cool air from the outside. It was 76 outside by 9pm, 68 inside. And by midnight, it was 72 outside, 65 inside.

2- Noise is minimal. You can hear the fan when on. There are 2 settings - low, mid and high. At the highest level the fan is at a comfortable noise level. Can’t hear it throughout the house. Hubby likes it because it’s subtle white noise that helps him sleep.

3- Installation is a beast. The installation of the foam side pieces included with the fan is the worst brain idea of any human I’ve seen in a long time. One would think a designer/manufacturer would incorporate the slide left/right shields to fill the gaps on the sides we see in other larger fans. Nope. It’s multiple sided poorly made foam pieces. And if you ever played with the toy that has shape holes and plastic shapes to fit inside - or the game Perfection - this install process takes you right back there. Inserting the fan into the window takes less than 30 seconds. Installing the foam inserts so they fit right and actually stay in place takes the better part of a half hour. And if you remove the fan completely due to a cold spell for a few days, you will dread having to reinsert it. Hubby got scolded for removing the fan I spent an hour installing. He is now ordered to put a pillow in front of the fan if he doesn’t want the cool air to enter the room.

4- The cost is absurd for this unit. This is a $25 to $30 fan. Not $70plus. You are paying for the slim low sitting profile. There is no remote or Bluetooth option. We are ok with that. But given the force of air flow in and out as far as the motor is concerned, it equates to a small $20 desk fan.

We aren’t sure if we are keeping. We need to give it another week or two when the summer weather is at its truest level in temperature. I should also note we bought new but received used, too. Since these do not come from an Amazon warehouse but from a private seller, shame on the seller for passing off used items as new at new cost. Just my opinion.

I agree with most of the reviews about the awkwardness of the foam spacers and the gaps along the top and bottom. But, my review for the fan itself is great. Love the low profile and short depth. It fits in my window without having to take out the screen. And it is very quiet. I can leave it on the 2nd setting and I barely hear it. It keeps the air in my room from getting stale. If I need extra ventilation for smoke or whatever, the 3rd setting purges the air quickly. Absolutely love this fan.

Surprised how this is holding up. I'm using it to replace a header about a door in a small outdoor garden studio and it's fantastic. The reverse airflow means it can help to dry out the space during times of high humidity and also provides some cooling when its hot. I'm impressed. Not loud at all.

I love this fan. We have no vent for our stove so we thought we'd give this a try. It is great. It sucks out all smoke, smells, etc. I use it to bring in fresh air as well.
The ease at which I can change vent direction is so useful. We had it in all winter and it doesn't let in too much cold air. Highly recommended.
