DREO HM735S 11L Smart Cool Mist Humidifier, 700 ft² Coverage, App Control

For households looking to manage humidity across a larger room, the DREO HM735S pairs an 11L tank with cool mist coverage for areas up to 700 ft². Its top-fill design makes refilling part of the regular routine more straightforward.

Choose a compact humidifier for a single bedside spot, or a larger-capacity model when you want coverage for a shared living area. The HM735S is designed for the latter, with app, remote, touch and voice control for convenient adjustments around the home.

For bedrooms and nurseries, its sleep mode, 26–32 dB noise range and adjustable RGB night light add practical comfort features. An aroma box provides another way to tailor the room’s atmosphere.

What to know

This ultrasonic humidifier produces cool mist and is rated for rooms up to 700 ft². Its 11L capacity and maximum runtime of 100 hours can help reduce how often you need to refill during ongoing use. Actual runtime will vary with settings and conditions, so the stated maximum is best understood as a reference rather than a fixed schedule.

Set humidity and schedules through the DREO app, or use the remote, touch controls or voice control. Auto mode helps manage operation around your chosen humidity settings, while cleaning reminders and a 12-hour timer support a more organized routine. The mist outlet adjusts through 360°, giving you flexibility in directing mist within the room.

The top-fill tank is useful when you want to refill without making the process a bigger household task. For nighttime use, sleep mode and the adjustable RGB light let you adapt the sound and ambience to the room. A child lock and automatic shut-off are also among its listed features. Buyers often praise the quiet operation, refill convenience and room coverage, opinions on humidity output and durability are more mixed.

Tips for day-to-day use

Place the humidifier where its mist can circulate through the space, then use the adjustable outlet to direct it as needed. Top-fill access helps make routine refills simpler, while the water-level window and low-water indicator make it easier to keep track of the tank. Use the app or controls to adjust humidity, set a timer or schedule operation, and follow cleaning reminders as part of regular care.

In a bedroom, sleep mode and the night light can suit evening use, in a living room or other shared space, the larger stated coverage and adjustable mist direction are the more relevant features. The aroma box offers an additional option when you want to add fragrance to the room.

Getting the most from it

Think about the space you want to humidify and how you prefer to manage a home appliance. This model brings room coverage, a large water capacity and several control methods together, so you can make adjustments from the unit or remotely rather than relying on touch controls alone. App scheduling and humidity settings are especially useful for fitting operation around a daily routine, while the remote offers a direct alternative.

Its rectangular shape and dimensions of 26D × 22.5W × 78.5H centimetres give you practical details for choosing a spot before filling the tank. The unit is suited to a range of spaces, including bedrooms, living rooms, nurseries, offices and study rooms. For smaller, localized use, a more compact approach may be preferable, the HM735S is intended for broader room coverage.

Should you buy it?

The DREO HM735S is a strong match for households that want cool mist for a larger room, fewer routine refills and flexible control options. Its 11L tank, coverage up to 700 ft², top-fill design and app, remote and voice controls support everyday use across shared spaces as well as bedrooms. Sleep mode, an adjustable night light and the aroma box add useful touches when a humidifier is part of your evening routine.
