How this humidifier scores for different use cases
Full WiFi connectivity with AiDot app, Alexa and Google Home compatibility, real-time humidity monitoring, scheduling, and remote control make this a top smart home pick at its price point.
Noise as low as 23dB in sleep mode, adjustable night light, 90-hour runtime on 6L tank, and auto shut-off make this excellent for overnight bedroom use. Timer options (1, 2, 4, 8 hours) add convenience.
BPA-free materials, cool mist only, 23dB sleep mode, and auto shut-off check all the critical nursery safety boxes. App control lets parents monitor and adjust without entering the room.
505 sq ft coverage and 550mL/h BoostMist output handle large rooms well. However, it lacks dual mist or warm mist options that whole-home units often provide for winter use.
At 6.3 x 10.31 x 13.64 inches and 4.36 lbs, this is too large for most desks. It requires a wall outlet and is designed for room-level use, not personal desktop humidification.
At 4.36 lbs with a 6L tank and no USB power option, this is not designed for travel. It is a full-size room humidifier that requires AC power.
Our Verdict
The WELOV H600 Pro packs serious mist power into a mid-price smart humidifier. Its 550mL/h output covers rooms up to 505 sq ft fast.
You get full app control through AiDot. Alexa and Google Home work too. Set schedules, check humidity, or adjust mist from your phone.
The 6L tank lasts up to 90 hours on low settings. That means fewer trips to the sink. Top-fill design makes refills quick and mess-free.
Sleep mode drops noise to 23dB. That is quieter than a whisper. The adjustable night light adds a gentle glow for nurseries.
BPA-free materials and auto shut-off keep your family safe. The built-in humidistat tracks room humidity and adjusts automatically.
You do lose out on warm mist. If you want steam for cold relief, look elsewhere. But for cool mist with smart features, this delivers strong value at $58.99.
What We Like
- BoostMist puts out 550mL/h, raising humidity 20% in just 10 minutes
- 6L tank runs up to 90 hours so you refill less often
- Sleep mode drops noise to just 23dB for quiet nights
- WiFi app plus Alexa and Google Home let you control it from anywhere
- Top-fill design with wide opening makes cleaning and refilling simple
What Could Be Better
- No warm mist option for cold and flu season relief
- No dual mist mode to combine warm and cool output
- No physical remote control included in the box
- Essential oils go in a tray only, not in the water tank
- Coverage tops out at 505 sq ft, not enough for very large open spaces
