DREO Tower Fan 519S Review: Smart 42-Inch Bladeless DC Fan

Updated October 22, 2026
The DREO Tower Fan 519S is the smart version of DREO’s popular 42-inch DC tower. It pairs 28 ft/s winds and 1397 CFM of air with Alexa, Google Assistant and the DREO app, and its listing has a 4.6 out of 5 average from 22,279 ratings. It is our top bladeless pick on our list of tower fans.
Our Verdict
The 519S is built for large bedrooms and living rooms in a smart home. Auto mode senses your cooling needs during the hottest hours and adapts the wind speed, Sleep mode lowers the speed and dims the display, and voice control means you never need to find the remote. The DC brushless motor draws 30 watts.
It has 9 speeds and a 90 degree sweep, fewer than the Pilot Max, and it costs more than the non-smart 519. Pay for the Wi-Fi only if you will use it.

Airflow and Coverage
DREO built the 519S for large spaces, with 28 ft/s fast winds and a massive 1397 CFM of air volume. That cools a large bedroom or living room quickly, and 90 degree oscillation spreads the air across the room.
Smart Features
Alexa and Google Assistant let you control the fan with a few words, and the DREO app gives you full control even when the remote is out of reach. Auto mode senses the room during the hottest part of the day and adapts the wind speed, so you stay cool without touching anything.
Setup takes a few minutes in the app on a 2.4 GHz network.
Noise and Sleep
The DC brushless motor is optimized for silent performance, with a 25 dB low setting in the specifications. One touch of Sleep mode adjusts the wind speed and dims the display lights for bedtime.
Energy Use
At 30 watts, the 519S is one of the most efficient 42-inch towers we cover, so it costs very little to run for hours.
How It Compares
Against the non-smart DREO 519, the 519S is the same fan with Wi-Fi and voice control added. Against the DREO Pilot Max, it has fewer speeds and a narrower sweep but a larger ratings base and a lower price.
Against the PELONIS smart bladeless tower, the DREO moves more air and has a much bigger ratings record, while the PELONIS is rated a little quieter at 22 dB.
Setup and Everyday Use
Setup is simple: assemble the base, plug the fan in and pair it with the DREO app on a 2.4 GHz network. Once linked, you can add it to Alexa or Google Assistant and control it by voice from any room.
Many owners will lean on Auto mode during the day and Sleep mode at night. Between the two, the 519S can run for weeks with almost no manual adjustment, which is the real benefit of paying for the smart version.
