Last summer, we went hands-on with the Dreo Polyfan 513S, and it immediately went into regular use in our home. Well, it’s a year later, and we all know Dreo is constantly iterating on their fan lineup. So, we’ve been spending time with the Dreo Polyfan 704S, and have some thoughts.
Dreo Polyfan 704S: what’s different?
In that gallery just above, we’ve got the Dreo Polyfan 704S (left) next to the 513S (right). As you can see, there’s definitely some styling updates. On the main upright stem, the large LCD display is gone, replaced by the touch-sensitive controls (these were on the fan unit on the 513S). So, how can you tell how fast the fan is spinning? There’s a hidden display just above the rotation pivot point. They’ve also included a nice remote holder, so you’ll always know where it’s at.
How is it a smart fan?
That’s the big question, right? For one, the fan connects to your wifi network, and you can control the unit directly from your phone. Above, you can see some screenshots of what the app allows you to control. You’ll notice in that first one it’s reporting the temperature in the room. With that sensor, you can have the fan work almost like it’s on a thermostat, kicking into higher speed when it’s too hot, and slowing down once it hits a set temp.
You can also setup schedules, adjust what mode the fan is moving air in, and adjust how you want the oscillation (side-to-side and/or up-down) to behave, setting the limits of both. This is great, because you may have it in a room where it ends up oscillating and blowing air just into a wall or bookcase. With this control, you can stop it before it swings to that, getting it back to moving the air in the room.
What it’s like using the Dreo Polyfan 704S
In a word? Simple. Once you’ve got the fan plugged in and on your network, adjusting things from your phone is a breeze (or even checking to see if you forgot to turn it off before you left the house). Don’t have your phone handy? There’s that handy wireless remote that can control it. And you know what? If you have other Dreo units around, the same remotes will work across the devices. Maybe not for all the features, but to turn it on or off, or adjusting the fan speed? Yup, that works.
We’ve had it setup in the bedroom for a bit now, and it’s been great to keep the room cool. The oscillation works, but we often just have it angled up towards the ceiling (stationary) and circulating the air that way. Even at a level where it keeps the room cool on the 90+ degree days, it’s not over-bearingly noisy.
Wrapping things up
When it came to fans, I had a certain brand I’d always default to when it came to setting things up to cool rooms down in the house. Now, I think Dreo is moving into the top spot for consideration. At $149.99, the Dreo Polyfan 704S is not an inexpensive fan. But it is a fan that can keep a room cooled down, and the ability to control it from your phone, or automate things via schedules or temperatures, are a definite boon. If you want to get one, you can get it directly from Dreo or of course over at Amazon.
