Let customers speak for us
Was a little skeptical when this product appeared in my feed, but the purchse was seemless, shipped from Canada, and was delivered quickly, thanks!
It's working well, I will buy a second for another problem room.
Id love a way to control led brightness through the app
Also, when pairing with ecobee, it would be great if you could designate which room sensor covers the smart fan.
But overall I am very happy with the device.
Great Product .It worked as claimed. Also support team is also amazing quickly reply and solved my issue . This product is way ahed then any other competition.
Immediately our room felt cooler. Finally solved the problem in our 3 storie townhouse where it never was cool enough. I might need more of these. So easy to install and the app is simple to control and program the fan. I was very happy to discover that the speeds were also adjustable. Love love love it.
It’s been one week but the difference is significant. I am currently using 2 x 4 inch and 2 x 3 inch units. The fans can be scheduled to operate in various modes and fan speeds based on time of day. The ability to control and adjust remotely is important. I look forward to the evolution of future products
3rd fan, and now we have all 3 rooms on the upstairs level of our home synced with our nest thermostat. Hot days are cool, cold days are warm! Awesome, thanks Smart Cocoon👏
The booster fans made a definite difference in the comfort level of our upstairs rooms. They are much more effective when the room doors are kept closed. They definitely brought more cool air to the 2nd floor. Closing the doors helps keep the cool air from settling down the stairs. I order more for two other family members with similar issues.
Bought two Smart Cacoons as the bedrooms on the second floor never really cooled down during the summer. They work exteremly well and now the bedrooms and the main floor are about the same temperature.
They are Awesome and wish I had them for many years.
Excellent service and communications. I had no problem with communicating with staff and they responded very fast. Smart Cocoon works really well winter and summer for us.
Great booster fan, can be controlled by phone.no more hot or cold upstairs room.
During this extreme heatwave (June 2025) I was a bit skeptical—but compared to how my 3rd floor felt before I easily installed and synced the Cocoon booster— I’m convinced! I felt an immediate difference in temperature and humidity. I especially like the app and that I can control the fan speed and temperature from my phone. If it works during these extreme temperatures I’m confident it’ll work all the time. Great product 👍🏻
I find it very suitable for small rooms such as bedrooms
I’m so surprised at how well this works, we have an upstairs south facing bedroom that is easily 15 degrees hotter than the rest of the house, and unbearable to sleep in. This little fan has reduced the temp by a good 10 degrees, during the peak heat of the day and helps to cool the room off quicker at night. We have a standard thermostat and the systems were fast and easy to set up.
