Summary

The DREO 713S is a 6-liter warm and cool mist humidifier with app and voice control, an accurate humidity sensor and a 6L top-fill tank. Check the model number before you buy: DREO sells several 6L units with similar names, and some buyers receive a non-WiFi version.

Strengths

  • Cool mist performance was the strongest in CNET’s 12-humidifier test.
  • The 6L tank was the largest in that comparison and fills easily from the top.
  • Owners report quiet operation and a humidity sensor that holds a set level accurately.
  • Warm mist helps with sinus relief and reaches temperature in about 5 minutes.
  • The app offers cleaning reminders and video maintenance guides.
  • Demineralization cartridges let it run on tap water without white dust.

Weaknesses

  • Warm mist gurgles and boils loudly enough to disturb light sleepers.
  • Hard water leaves calcium buildup unless you use demineralization cartridges.
  • Variant confusion is common: some buyers get a non-WiFi unit despite the listing.
  • Warm mist draws 280 W, so running it overnight costs noticeably more than cool mist.
  • The warranty is only one year, shorter than several rivals.
  • Cartridges need tracking; they last about 40 gallons.

Warm mist, cool mist and noise

CNET tested 12 humidifiers in February 2026 and named the HM713S a runner-up for smart humidifiers, measuring the strongest cool-mist output in the group. Its warm mist was less powerful than the Levoit OasisMist 450S, which gained about 14 humidity points in 10 minutes against Dreo’s 4 fewer. Airflow maxed at 1.2 m/s through a single adjustable nozzle. Owners on Reddit back up the quiet claim and the accurate hygrometer, though several note the warm-mist boiler gurgles.

Filters, water and cleaning

The tank and atomizing sheet need manual cleaning, and DREO recommends distilled water to avoid white powder. Demineralization cartridges, sold separately, handle tap water and last about 40 gallons, so plan on replacing them on a schedule. CNET singled out the app’s cleaning reminders and video guides as more useful than Levoit’s weekly-only reminder.

Is it worth it?

DREO sells the 713S for $89.99, and Kohl’s lists it at $99.99 with a one-year warranty. Below about $80 it is a strong pick for a dual-mode smart humidifier; from $81 to $100 it is fair. Above $100 you can find alternatives with stronger test histories. The main advantages are the dual warm and cool modes, the 6L tank and the low price.

Which model this is

This is the DREO Smart Humidifier 713S 6L. DREO also sells 6L models named 524, 524S and 813S, plus the 8L 717S, so confirm the model number DR-HHM013S before ordering; some retailer listings show DR-HHM003 instead. The Amazon page for this model is ASIN B0D3V9R4RQ.
