Is the Dreo HM713S worth it at $89.99?

At $89.99 at Amazon as of November 4, 2026, it is a reasonable buy for a quiet 6 L humidifier with warm mist and app control. Comparable smart humidifiers often cost more, though simpler models cost less.

How long does the tank last?

Up to 60 hours on the lowest setting. At the full 0.5 L/h output, a 6 L tank lasts about 12 hours, so expect one fill per night on high.

Does it work with Alexa or Google Home?

Dreo's smart humidifiers typically pair with the Dreo app and support voice assistants. Check the listing for the exact assistants supported on the HM713S.

What size room does it cover?

Dreo rates it for rooms up to 550 square feet. In very dry or open spaces, expect to run it on high and refill more often.

Does it leave white dust?

Ultrasonic humidifiers can leave mineral dust when filled with hard tap water. Use distilled or filtered water, or a demineralization cartridge, to reduce it.

Typically the humidifier, a power adapter and a manual. Check the listing for any included cleaning brush or filter.

Our take on the Dreo HM713S Smart Humidifier

The Dreo HM713S is a 6-liter ultrasonic humidifier that runs up to 60 hours on a fill and covers rooms up to about 550 square feet. It adds a warm mist mode that heats water to roughly 56 °C, plus touch controls and app-based smart features. Output is 0.5 liters per hour, so a full tank lasts about 12 hours on high and much longer on low. At $89.99 at Amazon as of November 4, 2026, it sits at the low end of its recent price range.
